ST was formed in 1987 by the merger of two government-owned semiconductor companies: Italian SGS Microelettronica (where SGS stands for Società Generale Semiconduttori, "General Semiconductor Company"), and French Thomson Semiconducteurs, the semiconductor arm of Thomson.
SGS Microelettronica originated in 1972 from a previous merger of two companies:
Thomson Semiconducteurs was created in 1982 by the French government's widespread nationalization of industries following the election of socialist François Mitterrand to the presidency. It included:
At the time of the merger of these two companies in 1987, the new corporation was named SGS-THOMSON and was led by chief executive officer Pasquale Pistorio. [3] The company took its current name of STMicroelectronics in May 1998 following Thomson's sale of its shares. After its creation ST was ranked 14th among the top 20 semiconductor suppliers with sales of around US$850 million. The company has participated in the consolidation of the semiconductor industry since its formation, with acquisitions including:

On December 8, 1994, the company completed its initial public offering on the Paris and New York stock exchanges. Owner Thomson SA sold its stake in the company in 1998 when the company also listed on the Italian Bourse in Milan. In 2002, Motorola and TSMC joined ST and Philips in a new technology partnership. The Crolles 2 Alliance was created with a new 12" wafer manufacturing facility located in Crolles, France. In 2005, chief executive officer Pasquale Pistorio was succeeded by Carlo Bozotti, who then headed the memory products division and had been with the company’s predecessor since 1977.[3] By 2005, ST was ranked fifth, behind Intel, Samsung, Texas Instruments and Toshiba, but ahead of Infineon, Renesas, NEC, NXP Semiconductors, and Freescale. The company was the largest European semiconductors supplier, ahead of Infineon and NXP.
Early in 2007, NXP Semiconductors (formerly Philips Semiconductors) and Freescale (formerly Motorola Semiconductors) decided to stop their participation in Crolles 2 Alliance. Under the terms of the agreement the Alliance came to an end on December 31, 2007.[6] On May 22, 2007, ST and Intel created a joint venture in the memory application called Numonyx: this new company merged ST and Intel Flash Memory activities. Semiconductor market consolidation continued with ST and NXP announcing on April 10, 2008, the creation of a new joint venture of their mobile activities, with ST owning 80% of the new company and NXP 20%. This joint venture began on August 20, 2008. On February 10, 2009, ST Ericsson, a joint venture bringing together ST-NXP Wireless and Ericsson Mobile Platforms, was established.[7]
ST Ericsson was a multinational manufacturer of wireless products and semiconductors, supplying to mobile device manufacturers.[8] ST-Ericsson was a 50/50 joint venture of STMicroelectronics and Ericsson established on February 3, 2009, and dissolved on August 2, 2013. Headquartered in Geneva, Switzerland, it was a fabless company, outsourcing semiconductor manufacturing to foundry companies.

In 2011, ST announced the creation of a joint lab with Sant'Anna School of Advanced Studies. The lab focuses on research and innovation in biorobotics, smart systems and microelectronics.[9] Past collaborations with Sant'Anna School of Advanced Studies included DustBot, a platform that integrated self-navigating "service robots" for waste collection.[9]
In 2018, chief executive Carlo Bozotti was succeeded by Jean-Marc Chery.[10] In 2023, STMicroelectronics partnered with Synopsys to design a working chip on Microsoft Corp’s cloud, marking the first time AI software had been utilized for chip design. [11]
As of December 31, 2014, the shareholders were:[12]
Unlike fabless semiconductor companies, STMicroelectronics owns and operates its own semiconductor wafer fabs. The company owned five 8-inch (200 mm) wafer fabs and one 12-inch (300 mm) wafer fab in 2006.[citation needed] Most of the production is scaled at 0.18 μm, 0.13 μm, 90 nm and 65 nm (measurements of transistor gate length). STMicroelectronics also owns back-end plants, where silicon dies are assembled and bonded into plastic or ceramic packages.[13]
Major sites include: [citation needed]
Grenoble is one of the company's most important R&D centres, employing around 4,000 staff. The Polygone site employs 2,200 staff and is one of the historical bases of the company (ex SGS). All the historical wafer fab lines are now closed but the site hosts the headquarters of many divisions (marketing, design, industrialization) and an important R&D center, focused on silicon and software design and fab process development.[14]
The Crolles site hosts a 200 mm (8 in) and a 300 mm (12 in) fab and was originally built as a common R&D center for submicrometre technologies as part of the 1990 Grenoble 92 partnership between SGS-Thomson and CNET, the R&D center of French telecom company France Telecom.[15] The 200 mm (8 in) fab, known as Crolles 1, is the company's first and was built as part of a 1991 partnership between SGS-Thomson and Philips to develop new manufacturing technologies. Crolles 1 was opened on September 9, 1993 by Gérard Longuet, French minister for industry, and Alain Carignon, mayor of Grenoble.
The 300 mm (12 in) fab was inaugurated by French president Jacques Chirac, on February 27, 2003. It includes an R&D center which focuses on developing new nanometric technology processes for 90-nm to 32-nm scale using 300 mm (12 in) wafers and it was developed for The Crolles 2 Alliance. This alliance of STMicroelectronics, TSMC, NXP Semiconductors (formerly Philips semiconductor) and Freescale (formerly Motorola semiconductor) partnered in 2002 to develop the facility and to work together on process development.[16] The technologies developed at the facility were also used by global semiconductor foundry TSMC of Taiwan, allowing TSMC to build the products developed in Crolles on behalf of the Alliance partners who required such foundry capacity. A new fab is under construction since 2015.
Employing around 3,000 staff, Rousset hosts several division headquarters including smartcards, microcontrollers, and EEPROM as well as several R&D centers. Rousset also hosts an 8-inch (200-mm) fab, which was opened on May 15, 2000 by French prime minister Lionel Jospin.[17][18]
The site opened in 1979 as a 100 mm (3.9 in) fab operated by Eurotechnique, a joint venture between Saint-Gobain of France and National Semiconductor of the US. Rousset was sold to Thomson-CSF in 1982 as part of the French government's 1981–82 nationalization of several industries. As part of the nationalisation, a former Thomson plant in the center of Aix-en-Provence operating since the 1960s was closed and staff were transferred to the new Rousset site. The original 100 mm (4 in) fab was upgraded into 130 mm (5 in) and later 150 mm (6 in) fab in 1996. It is now being shut down. The site also has a "Wafer Level Chip Scale Packaging" accreditation for eSIM ICs.[19]
In 1988, a small group of employees from the Thomson Rousset plant (including the director, Marc Lassus) founded a start-up company, Gemalto (formerly known as Gemplus), which became a leader in the smartcard industry.
Employing 1,500 staff, this site hosts a fab and R&D centers.[20]
Employing 6,000 staff, the Milan facilities match Grenoble in importance. Agrate Brianza employs around 4,000 staff and is a historical base of the company (ex SGS). The site has several fab lines (including a 300 mm (12 in) fab) and an R&D center.[21] Castelletto, employs 300 to 400 staff and hosts some divisions and R&D centers.
Update-2012: Numonyx JV (with Intel) is acquired by Micron. As such, R2 Fab (Agrate previous R&D 200-mm Fab) is currently a Micron entity
The Catania plant in Sicily employs 5,000 staff and hosts several R&D centers and divisions, focusing on flash memory technologies as well as two fabs. The plant was launched in 1961 by ATES to supply under licensing to RCA of the US and initially using germanium. The site's two major wafer fabs are a 200 mm (8 in) fab, opened in April 1997 by then-Italian Prime Minister Romano Prodi, and a 300 mm (12 in) fab that has never been completed and which was transferred in its current state to "Numonyx" in 2008. A new manufacturing facility for silicon carbide (SiC) substrates of 150 mm should open here in 2023.[22]
In October 2022, the EU supported STMicroelectronics for the construction of a silicon carbide wafer plant in Catania with €293 million through the Recovery and Resilience Facility to be completed in 2026, and in line with the European Chips Act.[23]
STmicro eSIM and SIM production facility for embedded form factor eSIM.[24]
As of 2010, ST employed some 1,500 people in Kirkop, making it the largest private sector employer, and the country's leading exporter.[25]
In 1970, SGS created its first assembly back-end plant in Singapore, in the area of Toa Payoh. Then in 1981, SGS decided to build a wafer fab in Singapore. The Singapore technical engineers have been trained in Italy and the fab of Ang Mo Kio started to produce its first wafers in 1984. Converted up to 200 mm (8 in) fab, this is now an important 200 mm (8 in) wafer fab of the group. Ang Mo Kio also hosts some design centers.[26] As of 2004, the site employed 6,000 staff.[27]
Update-2012: Numonyx JV (with Intel) is acquired by Micron in 2010. As such, AMK8 Fab (200mm HVM Fab) is currently a Micron entity. AMK5 and AMK6 remains to be STM entities. Update-2019: AMK8 has been reacquired by STM from Micron.
