Chiplet

A chiplet is a small, modular semiconductor die optimized for a specific function, such as processing, memory, or input/output, that can be interconnected with other chiplets to form a larger system-on-chip (SoC) or multi-die package.^[1]^[2] This disaggregated approach enables heterogeneous integration, where components manufactured on different process nodes are combined using advanced packaging techniques like 2.5D interposers or 3D stacking.^[3]^[4] The concept of chiplets builds on earlier multi-chip module technologies from the 1980s and 1990s, evolving to address the slowing pace of Moore's Law by fragmenting complex SoCs into reusable, specialized blocks.^[1] Key milestones include the U.S. Defense Advanced Research Projects Agency (DARPA) Electronics Resurgence Initiative's CHIPS program launched in 2017, which aimed to create modular design flows and a catalog of interoperable chiplets, involving partners like Intel and Cadence.^[2] The Universal Chiplet Interconnect Express (UCIe) standard, first established in 2022, was advanced with version 2.0 in 2024 to further facilitate high-speed die-to-die communication and promote ecosystem-wide compatibility, including support for 3D stacking.^[1]^[3]^[5] Chiplets offer significant advantages in cost, performance, and scalability, particularly for high-performance computing, AI, and data centers. By producing smaller dies, manufacturers achieve higher yields and reduce design costs by up to 70%, as smaller components are less prone to defects during fabrication.^[2] They also enable power efficiency by minimizing data movement— which can consume over 50% of a chip's energy—through closer integration of processors and memory.^[3] Additionally, chiplets support customization, allowing companies to mix legacy nodes for I/O with cutting-edge nodes for compute-intensive tasks.^[4] Despite these benefits, chiplet adoption faces challenges in interconnect density, thermal management, and standardization. High-speed links require pitches below 1 µm, often using hybrid bonding for 3D stacking at 200–700 nm resolutions, but this introduces latency, power overheads, and complexities in power delivery.^[1]^[4] Research efforts, such as those at IMEC, focus on advanced interposers with integrated capacitors and low-pitch redistribution layers to mitigate these issues.^[4] Major semiconductor firms have embraced chiplets for commercial products, driving innovation across industries. AMD pioneered widespread use in its EPYC processors starting in 2017, while Intel's Ponte Vecchio GPU and Apple's M1 Ultra employ multi-chiplet architectures for AI and high-performance computing.^[1] More recently, in 2025, Google introduced the Ironwood TPU employing multi-chiplet architecture for advanced AI inference. IBM is advancing 3D chiplet integration with through-silicon vias, and companies like NVIDIA and Google are integrating them into data center and automotive applications, signaling a shift toward modular ecosystems.^[3]^[4]^[6]

Fundamentals

Definition

A chiplet is a small, modular integrated circuit (IC) designed to perform a specific function, such as computation, memory access, or input/output operations, and is interconnected with other chiplets to form a larger system-on-chip (SoC) or multi-die package.^[7]^[8] This approach allows for the assembly of complex systems from specialized building blocks, mimicking the performance of a monolithic chip while leveraging modularity.^[9] Key characteristics of chiplets include their compact die sizes, often ranging from 50 mm² to 100 mm² or slightly larger depending on the function, which contrasts with the larger monolithic dies exceeding 500 mm² in high-performance applications.^[10] These smaller dies are optimized for targeted tasks, enabling heterogeneous integration where chiplets fabricated on different process nodes—such as advanced nodes for compute logic and mature nodes for I/O—can be combined within a single package.^[11]^[12] This modularity supports the use of diverse semiconductor technologies, including silicon, III-V compounds, or even non-silicon elements like photonics, to enhance overall system efficiency.^[13] While the term "die" refers broadly to any individual piece of processed silicon from a wafer, a chiplet is a specialized subset: a functional, unpackaged die engineered explicitly for interconnection and collaboration with other chiplets in a multi-die system, rather than standalone operation.^[2]^[12] For instance, in AMD's EPYC processors, a central I/O chiplet handles connectivity and memory interfaces, while multiple compute chiplets each containing CPU cores and cache are tiled around it to scale core count and performance.^[11]^[14] These interconnections, often via high-bandwidth interfaces like UCIe, ensure seamless data flow across chiplets.^[10]

Comparison to Traditional Designs

Traditional monolithic system-on-chip (SoC) designs integrate all functional components, such as processors, memory controllers, and I/O interfaces, onto a single large silicon die fabricated in one process.^[11] These designs are constrained by the semiconductor reticle size limit, typically around 800 mm², which restricts the maximum achievable die area and complicates scaling for increasingly complex systems.^[15] As die size grows to accommodate more transistors, manufacturing yields decline significantly due to the higher probability of defects occurring within the larger area.^[11] In contrast, chiplet-based designs disaggregate the SoC into multiple smaller, specialized dies that are subsequently packaged together, enabling the creation of larger effective systems without the reticle constraint. This modular approach contrasts with the all-in-one fabrication of monolithic dies, where every component must be produced on the same silicon substrate using identical process technology.^[11] Packaging techniques such as 2.5D integration with silicon interposers or 3D stacking via through-silicon vias allow these smaller dies to be interconnected at the package level, facilitating heterogeneous integration across different process nodes if desired.^[11] The yield advantages of chiplets stem from the exponential relationship between die area and defect probability, as described by the Poisson yield model: Y = e^{-D \cdot A}, where Y is the yield, D is the defect density (typically in defects per cm²), and A is the die area in cm². In this model, yield decreases rapidly with increasing area because a single defect anywhere on the die renders the entire monolithic chip unusable; partitioning into smaller chiplets isolates defects to individual modules, allowing the overall system yield to be the product of individual chiplet yields, which is substantially higher for large-scale designs. This evolution from single-die monolithic packages to multi-die chiplet systems addresses the limitations of traditional fabrication by prioritizing modularity and yield optimization, ultimately contributing to cost reductions in high-performance computing applications.^[11]

Historical Development

Early Concepts and Precursors

In the early 1990s, Japanese semiconductor pioneer Tsugio Makimoto proposed "Makimoto's Wave," a theory observing cyclical shifts in the electronics industry between periods of integration (customization, such as application-specific integrated circuits) and disaggregation (standardization, such as microprocessors), occurring roughly every decade due to technological maturity and economic factors.^[16] This framework anticipated a move toward modular designs as integration reached limits, influencing later explorations of disaggregated silicon architectures like chiplets by highlighting the benefits of standardization for reusability and cost efficiency.^[17] Early precursors to chiplet-based systems emerged through multi-chip modules (MCMs), which integrated multiple dies into a single package to overcome yield issues in large monolithic chips, particularly in high-performance computing. In the 1970s and 1980s, IBM pioneered MCMs for mainframe systems, initially for memory applications and later for thermal management, using ceramic substrates to house dozens of chips with dense interconnections.^[18] A notable example was IBM's Thermal Conduction Module (TCM) in the 3081 mainframe (introduced in 1980), which packed up to 133 chips per module with multilayer ceramic wiring, enabling over 370,000 circuits in uniprocessor configurations while supporting water cooling for reliability.^[19] By the 1990s, this evolved in the ES/9000 series, where MCMs facilitated up to six-way multiprocessing with 20 processor units, demonstrating modular scalability for enterprise computing without full monolithic integration.^[19] The term "chiplet" first appeared in patent literature in 1969, though initially in contexts unrelated to modern heterogeneous integration, such as LCD drivers.^[20] Practical application in integrated circuits began in the 1980s with IBM's modular processor designs, where smaller "chiplets" were assembled on shared substrates in MCMs to form complex systems, as seen in mainframe processors that divided functionality across dies for improved yield and repairability.^[20] During the 1990s and early 2000s, U.S. Defense Advanced Research Projects Agency (DARPA) programs advanced modular silicon concepts through initiatives like the Very Large Scale Integration (VLSI) project (1978–1980s, extending into the 1990s) and the MOSIS service (1981–1998), which decoupled chip design from fabrication to enable reusable intellectual property (IP) blocks and rapid prototyping.^[21] These efforts funded university research and provided standardized access to foundry capacity, fostering an ecosystem of fabless design and modular components essential for heterogeneous integration.^[22] Concurrently, initial 3D IC stacking concepts gained traction, with IBM developing wafer-level schemes in the late 1990s and early 2000s using layer transfer, oxide fusion bonding, and high-density vias (over 10^8/cm²) to stack functional dies vertically, addressing planar scaling limits while laying groundwork for chiplet-like vertical modularity.^[23]

Modern Milestones and Adoption

In 2015, AMD announced its Zen architecture, adopting a chiplet-based design to address the limitations of monolithic scaling at advanced process nodes, enabling modular construction of high-performance processors. This approach materialized in 2017 with the launch of AMD's EPYC server CPU, the first major commercial product featuring multiple Zen core chiplets integrated via Infinity Fabric, marking a pivotal shift toward scalable multi-die systems in data centers.^[24] Intel incorporated chiplet designs into its Xeon processors with the Sapphire Rapids generation in 2023, leveraging its Embedded Multi-Die Interconnect Bridge (EMIB) technology for hybrid integration, and extended this to the Ponte Vecchio GPU announced in 2019 for a 2022 release, which utilized EMIB to connect diverse compute tiles for high-performance computing.^[25] A landmark for industry-wide adoption came in 2022 with the announcement of the Universal Chiplet Interconnect Express (UCIe) standard, developed by Intel, Arm, TSMC, AMD, Samsung, Qualcomm, and others to enable interoperable chiplet ecosystems through standardized die-to-die interfaces.^[10] In August 2025, the UCIe Consortium released version 3.0 of the specification, supporting 64 GT/s performance and improved manageability features.^[26] Leading the charge in chiplet adoption are companies like AMD, which pioneered the approach in consumer and server CPUs; Intel, with its EMIB for heterogeneous integration; TSMC, via CoWoS advanced packaging for multi-chip modules; Samsung, advancing 4nm chiplet platforms for AI; and Broadcom, deploying chiplet architectures in AI networking switches like Tomahawk 6.^[27]^[28] From 2023 to 2025, Huawei's chiplet-related patents surged, including filings for quad-chiplet designs in AI accelerators like the Ascend 910D, reflecting accelerated innovation amid global supply constraints.^[29]^[30] This period also saw a consolidation wave, exemplified by Tenstorrent's 2025 acquisition of Blue Cheetah Analog Design to bolster interconnect IP for scalable AI chiplets, alongside strategic buys in die-to-die technologies across the ecosystem.^[31] By 2025, the chiplet market had reached approximately $52 billion in revenue, driven by rapid growth in AI and high-performance computing applications, with projections indicating continued expansion through modular designs.^[32]

Technical Aspects

Architecture and Components

Chiplet-based systems are composed of modular, function-specific dies that together form a larger integrated circuit, with core components including compute chiplets, accelerator chiplets, memory chiplets, and I/O chiplets. Compute chiplets typically house CPU or GPU cores optimized for general-purpose processing or parallel workloads, such as AMD's Zen CPU cores.^[11] Accelerator chiplets handle specialized tasks like AI/ML operations or custom arithmetic, offloading from main compute units to enhance efficiency.^[11] Memory chiplets integrate high-bandwidth memory (HBM) or other storage solutions, such as DRAM or emerging non-volatile types like MRAM, to support data-intensive applications with caching and coherency mechanisms.^[33] I/O chiplets manage external interfaces, including networking, analog connections, and memory controllers, serving as the system's boundary to the outside world.^[11] The modular design principles of chiplets emphasize independent optimization of intellectual property (IP) blocks, where each chiplet is developed and fabricated separately to leverage the most suitable technology for its function. This approach allows mixing process nodes across chiplets—for instance, advanced 5nm nodes for high-performance logic in compute chiplets alongside more mature 7nm or older nodes for I/O or analog functions—reducing overall design complexity and enabling reusability.^[4]^[34] At the system level, chiplet architectures rely on interconnect frameworks to enable communication, such as active interposers or direct die-to-die (D2D) connections, which facilitate high-speed data transfer between components. The Universal Chiplet Interconnect Express (UCIe) provides an open standard for these D2D interfaces, supporting interoperability across vendors with specifications for physical layer, protocol stack, and compliance testing.^[35] An active interposer, often a silicon-based layer with embedded logic, routes signals and manages connectivity in multi-chiplet packages, as demonstrated in early integrations achieving functional testing of heterogeneous dies.^[36] AMD's Infinity Fabric exemplifies a proprietary D2D interconnect protocol that provides scalable, coherent communication across chiplets, supporting bandwidths up to hundreds of GB/s in systems like the EPYC processors.^[11] Heterogeneity in chiplet designs extends to integrating diverse technologies, allowing analog and digital chiplets to coexist alongside specialized ones for photonics or sensors. Analog chiplets, often on mature nodes, handle signal processing or RF functions, while digital chiplets focus on logic; this combination requires compatible D2D interfaces for seamless operation.^[34] Photonic chiplets incorporate optical elements for high-speed data transmission, and sensor chiplets enable environmental or actuation capabilities, broadening applications in areas like imaging or quantum systems.^[37]^[38]

Manufacturing and Integration Methods

Chiplet fabrication leverages standard semiconductor foundry processes, such as TSMC's 3nm node, to produce smaller individual dies that can be later integrated into larger systems. These smaller dies typically exhibit significantly higher manufacturing yields compared to monolithic chips of equivalent total area, as defects are less likely to affect the entire component. For instance, yields exceeding 90% are achievable with smaller dies, in contrast to around 50% for large monolithic designs, due to the reduced impact of random defects across a smaller silicon area.^[39]^[40] Integration of chiplets primarily occurs through advanced packaging techniques, including 2.5D and 3D methods, to enable high-bandwidth communication between dies. In 2.5D integration, chiplets are mounted on a silicon interposer using microbumps for interconnections, as exemplified by TSMC's CoWoS (Chip on Wafer on Substrate) technology, which supports heterogeneous integration of logic, memory, and I/O components on a shared interposer for applications like high-performance computing.^[41]^[42] For 3D stacking, through-silicon vias (TSVs) provide vertical electrical connections between stacked chiplets, allowing denser packing and shorter signal paths without an interposer. Intel's Foveros technology advances this approach with direct face-to-face die stacking using hybrid bonding or microbumps, enabling vertical integration of compute and I/O chiplets to minimize latency in multi-die processors.^[43]^[44] A key challenge in chiplet packaging is ensuring reliability during assembly, addressed through known good die (KGD) testing, where individual chiplets are rigorously probed and validated for functionality and performance before integration. This pre-assembly testing mitigates risks of defective components propagating errors in the final package, thereby enhancing overall system yield and longevity.^[45]^[46] As of 2025, emerging trends in chiplet integration emphasize hybrid bonding, which directly joins copper pads and dielectrics between chiplets or wafers without solder, achieving interconnect pitches below 10 μm for higher density and reduced latency. This technique, already in high-volume manufacturing at 9 μm pitch, supports finer interconnections that improve signal integrity and power efficiency in advanced multi-chiplet designs.^[47]^[48]

Benefits

Economic and Yield Advantages

One key economic advantage of chiplet-based designs lies in improved manufacturing yields compared to monolithic integrated circuits. In traditional large-die production, yield decreases exponentially with increasing die area due to higher defect probabilities, following models such as the Poisson yield equation Y = e^{-D \cdot A}, where D is defect density and A is die area. By partitioning a system into smaller, independent chiplets, the overall system yield approximates the product of individual chiplet yields (Y_{total} = \prod Y_i), as each chiplet can be tested and only known-good dies (KGDs) are assembled. This multiplicative approach mitigates the yield penalty of scaling.^[49] This yield enhancement directly translates to cost reductions, as smaller dies utilize wafer real estate more efficiently, minimizing waste and lowering per-unit production expenses. Studies indicate that multi-chiplet integration can reduce die costs by up to 50%, particularly for advanced nodes where large monolithic yields are low. Additionally, chiplet reusability across product lines—such as AMD's Zen cores employed in both consumer and server processors—significantly cuts non-recurring engineering (NRE) costs by amortizing design and validation expenses, with potential savings of 75% in chip NRE for scaled systems. Smaller dies also enable higher throughput from the same fabrication capacity, further compressing recurrent engineering costs.^[49] Chiplet architectures enhance supply chain flexibility by allowing components to be sourced from multiple foundries, reducing dependency on a single supplier and mitigating risks from capacity constraints or geopolitical disruptions. For example, logic chiplets can be fabricated at TSMC on leading-edge nodes, while memory or I/O chiplets are produced at Samsung or other partners, enabling optimized cost and performance per module. This disaggregated approach supports heterogeneous integration without full redesigns. Market analyses show that such modularity shortens overall development timelines by 12-18 months, from traditional 24-36 months for monolithic SoCs, accelerating time-to-market and enabling faster iteration in competitive sectors.^[50]^[51]

Performance and Flexibility Gains

Chiplet architectures enable significant performance enhancements by minimizing inter-die communication latency through advanced interconnect standards like UCIe, which achieves sub-nanosecond die-to-die (D2D) latency for high-bandwidth data transfer.^[52] This low-latency connectivity supports efficient scaling of compute resources, as demonstrated in AMD's EPYC processors, where chiplet designs facilitate core counts exceeding 128, reaching up to 192 cores in the 9005 series for superior multi-threaded workloads.^[11]^[53] Heterogeneous integration in chiplet systems further boosts power efficiency by allowing advanced nodes for performance-critical "hot spots" while using mature processes for less demanding components, resulting in overall improvements in performance per watt. For instance, AMD EPYC processors leverage this approach to deliver higher computational throughput at reduced power consumption compared to monolithic designs.^[54] Such optimizations can yield up to 3x lower power for equivalent bandwidth in on-package memory integrations.^[55] The modular nature of chiplets provides substantial flexibility, enabling designers to upgrade specific components, such as swapping I/O chiplets to support emerging standards without redesigning the entire system. This modularity also accelerates time-to-market for custom system-on-chips (SoCs) by reusing pre-verified chiplet IP blocks, reducing development cycles from years to months in complex designs.^[56]^[57] Beyond traditional scaling limits, chiplets extend system capabilities post-Moore's Law by enabling 10x or greater integration density through heterogeneous packaging, circumventing the physical constraints of single-die fabrication. This approach has driven industry-wide efficiency gains of up to 12x in high-performance computing and AI applications over recent years.^[58]^[59]

Applications

In Computing Processors

In computing processors, chiplet architectures have enabled significant scaling in core counts for general-purpose central processing units (CPUs), particularly in server and desktop environments. Advanced Micro Devices (AMD) pioneered widespread adoption of this approach with its Ryzen and EPYC processor families, utilizing multiple core complex dies (CCDs)—each containing up to eight Zen cores—interconnected via the high-speed Infinity Fabric protocol. This modular design, first implemented in the second-generation EPYC "Rome" processors launched in 2019, allowed for up to 64 cores per socket by combining CCDs with a central input/output die, facilitating efficient multi-socket configurations for data center workloads while improving yield through smaller, specialized silicon components.^[11]^[60] Intel has similarly embraced chiplets in its Xeon Scalable lineup, transitioning to a tiled architecture in the fourth-generation Sapphire Rapids processors released in 2023. These CPUs integrate up to four compute tiles—each with 16 Golden Cove cores—using Intel's Embedded Multi-Die Interconnect Bridge (EMIB) for low-latency, high-bandwidth connections between heterogeneous components, achieving up to 60 cores per socket in standard configurations and supporting dual-socket systems for enhanced parallelism. The design separates compute, I/O, and accelerator tiles, optimizing for server scalability and incorporating features like DDR5 memory and PCIe 5.0 for demanding enterprise applications.^[61] More recently, as of 2025, Intel's Clearwater Forest Xeon processors utilize up to 12 CPU chiplets on the 18A process node, scaling to 288 E-cores for efficient server workloads with support for DDR5-8000 memory.^[62] Arm-based processors have also incorporated chiplets for data center CPUs, exemplified by Ampere Computing's AmpereOne family, which employs a disaggregated chiplet structure to scale to 192 cores across multiple dies connected via an advanced mesh interconnect. This enables high-performance, energy-efficient computing for cloud-native workloads, with each chiplet handling subsets of cores and I/O resources to support up to 8 TB of DDR5 memory per socket. In consumer applications, chiplet designs have democratized high multi-threading capabilities, as seen in AMD's Ryzen 9 series—such as the 16-core 3950X from 2019—delivering substantial gains in desktop productivity and content creation tasks through affordable scaling of core counts without monolithic die complexity.^[63]

In Specialized Systems

Chiplets enable modular designs in specialized systems like graphics processing units (GPUs) and embedded applications, allowing tailored integration of compute, memory, and I/O components for domain-specific demands such as AI acceleration and real-time processing. In GPUs optimized for AI and high-performance computing (HPC), AMD's Instinct MI300 series leverages a chiplet-based architecture built on the CDNA 3 compute platform, which combines multiple compute chiplets with stacked high-bandwidth memory (HBM3) for enhanced data throughput and scalability.^[64] The MI300X variant, for example, integrates eight HBM3 stacks in a 3D package with 153 billion transistors across its chiplets, delivering up to 304 compute units and 1,216 matrix cores to support large-scale generative AI training and inference.^[65] This approach addresses the limitations of monolithic dies by enabling higher memory capacity—up to 192 GB—and bandwidth exceeding 5 TB/s, critical for memory-intensive HPC simulations and AI model handling.^[66] NVIDIA's Blackwell GPU architecture represents a shift toward chiplet adoption in high-end graphics accelerators, deployed in AI data centers as of 2025. The B200 GPU employs a dual-die chiplet configuration using NVIDIA's High-Bandwidth Interface (NV-HBI) to link two reticle-sized compute dies, achieving 208 billion transistors on TSMC's 4NP process while supporting up to 192 GB of HBM3e memory.^[67] This design improves energy efficiency by 25 times over prior generations for AI inference tasks and facilitates scaling to superchip configurations like the GB200, which pairs the GPU chiplets with a Grace CPU for exascale computing.^[68] By avoiding full monolithic fabrication, Blackwell reduces yield risks for massive transistor counts and enables flexible performance tuning for AI factories.^[69] In embedded systems, chiplets facilitate heterogeneous integration in automotive system-on-chips (SoCs), where sensor fusion and compute domains require diverse process nodes and reliability standards. Renesas' fifth-generation R-Car SoC, unveiled in 2024, uses 3 nm process technology with chiplet extensions to create multi-domain controllers for advanced driver-assistance systems (ADAS) and centralized electrical/electronic architectures, combining high-performance compute chiplets with sensor interfaces for real-time processing.^[70] This modular approach allows automotive designers to mix legacy-node I/O chiplets for robustness with cutting-edge compute chiplets, improving scalability for autonomous vehicle workloads like object detection and path planning.^[4] Overall, disaggregating SoCs into chiplets enhances customization and yield in safety-critical embedded environments, enabling higher modularity for segment-specific vehicle models.^[71]

Challenges

Technical and Reliability Issues

One of the primary technical challenges in chiplet-based designs arises from thermal management, where the higher integration density of multiple dies on an interposer or substrate leads to localized hotspots and uneven heat dissipation. Heterogeneous chiplets, often fabricated on different process nodes, generate varying power densities, resulting in significant inter-die temperature gradients that can reach 20-30°C under heavy workloads, exacerbating stress on interconnects and reducing overall system performance.^[72]^[73] To mitigate these issues, advanced cooling solutions such as direct-to-silicon liquid cooling have been integrated into platforms like CoWoS, which improve heat extraction from hotspots by minimizing thermal resistance at multiple interfaces. However, inter-die variations continue to complicate uniform cooling, necessitating precise thermal modeling and placement optimization to balance heat flow across the package.^[73] Power delivery in chiplet systems introduces further engineering hurdles due to the need for power delivery networks (PDNs) that span multiple dies, often requiring advanced on-chip regulators to handle dynamic loads. Different chiplets may operate in varied power states, leading to uneven consumption and challenges in dynamic voltage scaling, while shared power rails can couple noise between domains, causing voltage drops and resonance effects that degrade signal integrity.^[74] Low-dropout regulators and isolated power islands are commonly employed to filter high-frequency noise and maintain stability, but limited space for decoupling capacitors at die interfaces heightens the risk of hotspots in the PDN.^[74] Co-simulation of on-die, interposer, and package-level PDNs is essential to address these multi-domain interactions and ensure efficient power distribution without excessive losses.^[75] Testing chiplets presents increased complexity compared to monolithic designs, particularly in validating known good die (KGD) and performing at-speed tests on high-speed die-to-die interconnects like those compliant with UCIe specifications. Pre-assembly KGD testing ensures only functional dies proceed to integration, but the heterogeneous nature of chiplets—spanning diverse process nodes and materials—demands specialized tools for simulating bit error rates, eye diagrams, and forward clocking under operational conditions, amplifying test time and cost.^[76] Interconnect defects, such as opens or shorts in dense bump arrays, can propagate system-level failures if unaddressed, with the large number of inter-die links potentially elevating defect rates by factors of 2-3 times relative to single-die equivalents without robust design-for-test (DfT) structures like IEEE 1838 or 1500.^[77] Built-in self-test (BIST) mechanisms and boundary scan techniques help detect these faults early, but the shift from wafer-level to multi-stage testing workflows remains a key bottleneck.^[76] Reliability concerns in chiplets are prominently driven by electromigration (EM) in interconnect elements like microbumps and through-silicon vias (TSVs), where high current densities induce void formation and phase transformations, accelerating failure under thermal stress. In multi-die configurations, EM effects are amplified by current crowding at bump interfaces and thermal gradients, necessitating materials like nanotwinned copper or nickel barriers to enhance resistance and delay crack propagation.^[78] Mean time between failures (MTBF) models for these systems must be adjusted to account for multi-die interactions, incorporating factors such as interconnect redundancy and stress-induced variations to predict long-term stability beyond monolithic baselines.^[79] Overall, these reliability issues underscore the importance of holistic monitoring and repair strategies, including spare lanes for interconnect failover, to maintain system integrity in operational environments.^[80]

Standardization and Ecosystem Barriers

One major barrier to widespread chiplet adoption lies in the fragmentation of interconnect standards, which complicates interoperability between dies from different manufacturers. The Universal Chiplet Interconnect Express (UCIe), an open standard released in March 2022 and updated to version 3.0 in August 2025, addresses this by specifying a complete die-to-die interface including physical layer, protocol stack, software model, and compliance testing, with support for data rates up to 64 GT/s per lane across scalable configurations of 16 to 64 lanes or more, along with enhanced manageability features like redundant lanes for failure replacement.^[81]^[35]^[82] However, competing proprietary and alternative standards persist, such as Intel's Advanced Interface Bus (AIB), a high-bandwidth, low-power parallel interface open-sourced in 2018 for die-to-die connections within packages up to 10 mm, and the Bunch of Wires (BoW) specification from the Open Compute Project, a simple, low-overhead interconnect already in use by at least 10 companies including Samsung.^[83]^[84] These alternatives, while effective in specific ecosystems, limit cross-vendor compatibility without additional adaptation. Intellectual property (IP) compatibility further exacerbates ecosystem challenges, as there is no universal marketplace for standardized chiplets, forcing designers to rely on proprietary architectures that restrict mixing components from multiple suppliers. This lack of a plug-and-play environment requires custom coordination for electrical, thermal, and mechanical integration, increasing design complexity and time-to-market.^[85]^[86] Proprietary IP disputes and licensing issues also arise in multi-vendor collaborations, hindering the emergence of a true open chiplet economy despite initiatives like UCIe.^[87] Supply chain dependencies amplify these barriers, with Taiwan Semiconductor Manufacturing Company (TSMC) holding dominant control over advanced nodes and packaging technologies essential for chiplets, contributing approximately 15% of its revenues from chiplet-related production in 2025.^[88] This concentration creates vulnerabilities, as disruptions in TSMC's operations could cascade across the global semiconductor industry. Geopolitical tensions, particularly US export controls on advanced chips to China, add further risks by limiting access for firms like Huawei to critical foundry services and interconnect technologies, reshaping supply chains and accelerating efforts toward regional diversification.^[89]^[90] As of 2025, these standardization and ecosystem hurdles result in slow overall adoption, particularly in consumer electronics where cost sensitivities and yield requirements favor monolithic designs, compared to faster uptake in servers and data centers for high-performance computing.^[88]^[91]

Future Outlook

Market Projections

The global chiplet market is forecasted to expand significantly. According to Marvell, chiplet revenue reached $43.5 billion in 2024.^[92] IDTechEx projects growth to $411 billion by 2035, with a compound annual growth rate (CAGR) of 14.7% over the 2025–2035 period.^[93] As of 2025, MarketsandMarkets estimates the market at $51.94 billion.^[32] This growth is propelled by escalating demands in high-performance computing (HPC) and artificial intelligence (AI), particularly for data center applications requiring scalable, modular designs.^[94] In the compute segment, which encompasses processors for servers and AI accelerators, revenues are expected to reach $144.9 billion by 2030, representing a substantial portion of the overall market driven by advancements in heterogeneous integration.^[92] Adoption of chiplet architectures is accelerating across high-performance applications, with projections indicating full mainstream integration by 2030 as supply chain ecosystems mature. In the server CPU domain, a 2023 projection estimated chiplet-based designs at approximately 24% of units shipped by 2025 (69 million out of 285 million total units).^[95] As of 2025, chiplet-based designs from vendors like AMD and Intel dominate the high-end server market. Regionally, the United States and Europe dominate chiplet design innovation, led by pioneers such as AMD and Intel, which have integrated chiplets into flagship products like EPYC processors and Xeon Scalable families to address complex computing needs.^[94] Conversely, Asia leads in manufacturing, with Taiwan Semiconductor Manufacturing Company (TSMC) commanding approximately 70% of the global foundry market share in 2025, enabling advanced packaging techniques essential for chiplet assembly.^[96] Revenue models in the chiplet ecosystem are evolving toward intellectual property (IP) licensing, allowing providers to monetize reusable modules and fostering a more disaggregated supply chain that reduces development costs for end-users.^[97] This shift is underscored by industry consolidations, including Qualcomm's $2.4 billion acquisition of interconnect specialist Alphawave Semi in June 2025 and Tenstorrent's purchase of analog IP firm Blue Cheetah in July 2025, aimed at securing critical technologies for multi-die systems.^[98]^[99]

Innovations and Trends

Advanced packaging techniques are evolving chiplet designs toward higher-dimensional integrations, such as 3.5D and 4D architectures, which enable denser stacking and interconnectivity beyond traditional 2.5D and 3D methods. These approaches incorporate photonics chiplets for optical input/output (I/O), addressing the bandwidth and latency limitations of electrical copper interconnects by leveraging light-based signaling. For instance, Ayar Labs' TeraPHY optical I/O chiplet facilitates high-speed data transfer in multi-chiplet systems, supporting applications in data centers and high-performance computing.^[93]^[93] Integration of photonics in chiplet packaging has demonstrated significant power efficiency gains, with glass substrates in advanced 3.5D and 4D configurations reducing power consumption by up to 50% compared to organic alternatives, due to improved signal integrity and lower dielectric loss. This reduction is critical for scaling chiplet-based systems while managing thermal challenges in dense assemblies.^[100]^[100] In the realm of artificial intelligence, domain-specific chiplets tailored for edge AI are emerging as key enablers of low-power, real-time processing. Neuromorphic designs, inspired by biological neural structures, integrate spiking neural networks and event-driven computation to optimize resource usage in resource-constrained environments like mobile devices and IoT sensors. Chips such as Intel's Loihi and BrainChip's Akida exemplify this trend, offering neuromorphic capabilities that reduce latency and energy demands for tasks like pattern recognition and anomaly detection at the edge.^[101]^[102] Chiplets promote sustainability by facilitating modular reuse of components, thereby extending product lifecycles and minimizing electronic waste. For example, AMD's chiplet-based 4th Generation EPYC processors reused existing IP blocks, avoiding approximately 50,000 metric tons of CO₂ equivalent emissions in 2023 through reduced fabrication needs. This modularity allows selective upgrades, discarding only faulty units rather than entire dies, which improves yields from 50% to 90% and cuts silicon waste.^[103]^[104]^[105] Trends in green fabrication facilities (fabs) further align with chiplet adoption, emphasizing shorter interconnects for lower energy use and advanced thermal management to enhance overall efficiency. Amid global e-waste reaching 62 million tonnes in 2022—with only 22.3% recycled—chiplets support circular economy principles by enabling material recovery and reduced virgin resource demands in semiconductor production.^[103]^[106] Looking toward 2030 and beyond, the Universal Chiplet Interconnect Express (UCIe) standard is expanding to foster universal marketplaces, standardizing die-to-die interfaces for multi-vendor interoperability and accelerating chiplet ecosystem growth. The UCIe 3.0 specification, released in 2025, supports data rates up to 64 GT/s, enabling scalable, power-efficient connections across diverse applications.^[82]^[107] Quantum-hybrid chiplets represent a frontier trend, combining classical and quantum processing elements in modular architectures to address complex simulations and optimization problems. As of November 2025, Rigetti Computing remains on track for demonstrations of multi-chip quantum systems targeting 100+ qubit chiplet-based designs with 99.5% fidelity by late 2025.^[108] In automotive and 5G sectors, chiplet adoption is driving growth through specialized components for advanced driver-assistance systems (ADAS) and high-bandwidth connectivity. The chiplet-based automotive components market is projected to expand from USD 6.5 billion in 2023 to USD 148 billion by 2028, fueled by demands for reliable, scalable semiconductors in electric vehicles and 5G-enabled telematics.^[109]
