History
Founding and Early Development
STMicroelectronics originated from the 1987 merger of two European semiconductor firms: Italy's SGS Microelettronica and France's Thomson Semiconducteurs, both initially government-controlled entities seeking to consolidate strengths amid global competition from U.S. and Japanese rivals.[4][5] The resulting company, initially named SGS-Thomson Microelectronics, was incorporated as a Dutch holding company with joint Italian-French ownership, reflecting the strategic alliance between the two nations to build a competitive pan-European player in discrete and integrated circuits.[9] SGS Microelettronica traced its roots to Italy's post-World War II industrial efforts, emerging in 1957 as the semiconductor arm of Olivetti, the typewriter and computing pioneer led by Adriano Olivetti, to supply components for internal electronics needs.[10] In 1972, it merged with ATES (Aquila Tubi e Semiconduttori), a vacuum tube and early semiconductor producer established in the 1950s, forming SGS Microelettronica with facilities in Agrate Brianza and sites producing diodes, transistors, and rudimentary ICs by the 1970s.[4][11] Thomson Semiconducteurs, meanwhile, was established in 1982 through the French government's nationalization under President François Mitterrand, consolidating the semiconductor operations of Thomson-CSF—a defense and electronics conglomerate with origins in the 1968 merger of CSF (Compagnie Générale de la Télégraphie Sans Fil) and Thomson-Brandt—along with other assets like those from Eurotechnique.[4][5] This entity focused on power devices, bipolar ICs, and consumer electronics chips, leveraging France's state-backed R&D amid the era's industry consolidations.[10] Post-merger, under CEO Pasquale Pistorio—who had led SGS since 1979 and orchestrated the union—the company prioritized technology transfer, joint investments in fabrication plants, and diversification into CMOS and bipolar processes, achieving early scale with revenues exceeding $1 billion by the early 1990s through sales in automotive, telecom, and computing sectors.[11][12] This foundation enabled survival in the cyclical semiconductor market, though initial challenges included integrating disparate cultures and aligning production amid European economic pressures.[5]Mergers, Acquisitions, and Expansion
STMicroelectronics originated from the 1987 merger of Italy's SGS Microelettronica and France's Thomson Semiconducteurs, both state-backed entities, forming SGS-Thomson Microelectronics to consolidate European semiconductor capabilities amid global competition.[10] The combined entity was renamed STMicroelectronics in 1998 following its listing on the New York and Paris stock exchanges, marking a shift toward independent operations with equal Italian and French government stakes initially.[10] This foundational merger integrated complementary technologies in microelectronics and discrete components, enabling scale in analog and digital IC production.[11] Subsequent acquisitions targeted diversification and market leadership. In 1993, ST acquired U.S.-based TAG Semiconductors to bolster American operations and assembly capabilities.[10] The late 1990s saw purchases of Metaflow Technologies in 1997 for processor expertise and Arithmos in 1999 for digital display chips, alongside Adaptec's hard disk controller division to dominate that segment.[10] Early 2000s deals included Nortel Networks' semiconductor unit in 2000 (later divested due to overcapacity) and Alcatel's microelectronics division for $345 million in 2002, securing DSL modem leadership.[10] [13] More recent strategic buys emphasized power electronics and edge computing. ST took a majority stake in Sweden's Norstel AB, a silicon carbide (SiC) wafer maker, on February 6, 2019, to advance high-voltage applications.[14] In March 2020, it acquired a majority in Exagan for gallium nitride (GaN) tech to accelerate power device innovation.[15] July 2020 acquisitions enhanced STM32 microcontroller wireless features, including Bluetooth and Zigbee IP.[16] The 2021 purchase of Cartesiam for $138 million integrated machine learning for industrial edge AI.[17] On July 24, 2025, ST agreed to acquire NXP's MEMS sensor business for up to $950 million ($900 million base plus $50 million in milestones), focusing on automotive and pressure sensors to strengthen its analog portfolio.[18] Expansion efforts centered on advanced manufacturing capacity. In the early 1990s, ST built a state-of-the-art fab in Grenoble, France, for 8-inch wafers to modernize production.[10] The 2005 Crolles2 alliance established a 12-inch wafer facility in Crolles, France, for collaborative R&D in advanced nodes.[4] Recent investments prioritize SiC for electrification: In October 2022, the EU granted €293 million for a SiC wafer plant in Catania, Italy; this expanded in May 2024 to a full 200mm SiC device, module, test, and packaging site. ST is also scaling SiC output in Singapore fabs and its Chongqing, China joint venture.[19] These moves address supply chain resilience and demand in EVs and renewables, with facilities spanning Europe, Asia, and the U.S.[19]Leadership Transitions and Strategic Shifts
