'''STMicroelectronics [[Naamloze vennootschap|NV]]''' (commonly referred to as '''ST''' or '''STMicro''') is a European [[multinational corporation|multinational]] [[semiconductor]] contract manufacturing and design company. It is the largest of such companies in [[Europe]]. It was founded in 1987 from the merger of two state-owned semiconductor corporations: ''Thomson Semiconducteurs'' of [[United States]]/[[France]] and ''SGS Microelettronica'' of [[Italy]]. The company is incorporated in [[the Netherlands]] and headquartered in [[Plan-les-Ouates]], [[Switzerland]]. Its shares are traded on [[Euronext Paris]], the [[Borsa Italiana]] and the [[New York Stock Exchange]].<ref>{{cite web |title=Stock data - STMicroelectronics |url=https://investors.st.com/stock-and-bond-information/stock-data |publisher=STMicroelectronics}}</ref>

== History ==
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 SA|Thomson]].

SGS Microelettronica originated in 1972 from a previous merger of two companies:
* ATES (Aquila Tubi e Semiconduttori), a vacuum tube and semiconductor maker headquartered in [[L'Aquila]], the regional capital of the region of [[Abruzzo]] in [[Southern Italy]], which in 1961 changed its name to Azienda Tecnica ed Elettronica del Sud and relocated its manufacturing plant in the Industrial Zone of [[Catania]], in [[Sicily]];
* [[Società Generale Semiconduttori]] (founded in 1957 by Italian engineer, politician, and [[industrialist]] [[Adriano Olivetti]]).

Thomson Semiconducteurs was created in 1982 by the French government's widespread nationalization of industries following the [[1981 French presidential election|election of François Mitterrand to the presidency]]. It included:
* the semiconductor activities of the French electronics company [[Thomson SA|Thomson]];
* in 1985 it bought [[Mostek]], a US company founded in 1969 as a spin-off of [[Texas Instruments]], from [[United Technologies]];
* Silec, founded in 1977;
* Eurotechnique, founded in 1979 in [[Rousset, Bouches-du-Rhône]] as a [[joint-venture]] between [[Saint-Gobain]] of France and US-based [[National Semiconductor]];
* EFCIS (Étude et la Fabrication de Circuits Intégrés Spéciaux), founded in 1972 at [[CEA-Leti: Laboratoire d'électronique des technologies de l'information|CEA-Leti]];
* SESCOSEM, founded in 1969.

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.<ref name=WSJ>{{cite news |title=STMicro Names CEO to Succeed Retiring Pistorio |url=https://www.wsj.com/articles/SB107934421459755360 |newspaper=Wall Street Journal |date=16 March 2004 |access-date=7 December 2023 |last1=Faucon |first1=Benoit |last2=Newswires |first2=Gren Manueldow Jones }}</ref> 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.

STMicroelectronics participated in the consolidation of the semiconductor industry from the start; it bought the following companies between 1989 and 2007, for instance:
 
* in 1989: British company [[Inmos]], known for its [[transputer]] [[microprocessor]]s, from parent [[Thorn EMI]];
* in 1994: Canada-based [[Nortel]]'s semiconductor activities;
* in 1999: UK-based VLSI-Vision CMOS Image Sensor research & development company, a spin-out of Edinburgh University.  Incorporated on 1 January 2000, the company became STMicroelectronics' Imaging Division, currently part of the Analog MEMS and Sensors business group;
* in 2000: WaferScale Integration Inc. (WSI, [[Fremont, California]]), a vendor of EPROM and flash-memory-based programmable system chips;<ref>{{Cite web|url=https://www.eetimes.com/stmicroelectronics-buys-waferscale-integration//|title=STMicroelectronics buys WaferScale Integration|first=Peter|last=Clarke|date=2000-07-28|website=[[EE Times]]|language=en-US|access-date=2020-12-09}}</ref>
* in 2002: Alcatel's Microelectronics division, which along with the incorporation of smaller ventures such as UK company Synad Ltd helped the company expand into the Wireless-LAN market;
* in 2007: US company [[Genesis Microchip]].<ref>{{cite web |url=http://investors.st.com/news-releases/news-release-details/stmicroelectronics-acquire-genesis-microchip |title=STMicroelectronics To Acquire Genesis Microchip |access-date=2018-06-27 |archive-date=2018-06-27 |archive-url=https://web.archive.org/web/20180627144523/http://investors.st.com/news-releases/news-release-details/stmicroelectronics-acquire-genesis-microchip |url-status=live }}</ref> Genesis Microchip is known for their strength in video processing technology ([[Faroudja]]) and has design centres located in [[Santa Clara, California|Santa Clara]], [[Toronto]], [[Taipei|Taipei City]] and [[Bangalore]].

On 8 December 1994, the company completed its initial public offering on the [[Paris Stock Exchange|Paris]] and [[New York Stock Exchange|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 (electronics)|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.<ref name="WSJ" /> 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.<ref>{{cite web|url=http://www.eetasia.com/ART_8800469769_480200_NT_19a4c517.HTM/ |title=Archived copy |access-date=July 15, 2013 |url-status=dead |archive-url=https://web.archive.org/web/20140101095429/http://www.eetasia.com/ART_8800469769_480200_NT_19a4c517.HTM/ |archive-date=January 1, 2014 }}</ref> 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.

Major sites include: {{Citation needed|date=February 2007}}

===Grenoble, France===
[[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 (semiconductors)|fab]] lines are now closed but the site hosts the headquarters of many divisions (marketing, design, industrialization) and a R&D centre, focused on silicon and software design and fab process development.<ref>{{cite web|access-date=2023-11-03 |date=2013-07-24 |title=STMicroelectronics celebrates "Nano2017" R&D program at Crolles facility |publisher=powersystemsdesign.com |url=https://www.powersystemsdesign.com/articles/d-program-at-crolles-facility/36/702}}</ref>

The [[Crolles]] site hosts a {{convert|200|mm|in|0|abbr=on}} and a {{convert|300|mm|in|abbr=on}} fab and was originally built as a common R&D centre for submicrometre technologies as part of the 1990 ''Grenoble 92'' partnership between SGS-Thomson and [[Centre national d'études des télécommunications|CNET]], the R&D center of French telecom company '''France Telecom'''.<ref>{{cite web|access-date=2023-11-03 |date= |title=The Controversy over Offshoring: Power, Resistance and Translations in the French Semiconductor Industry |publisher=strategie-aims.com |url=https://www.strategie-aims.com/conferences/23-xxiieme-conference-de-l-aims/communications/2894-the-controversy-over-offshoring-power-resistance-and-translations-in-the-french-semiconductor-industry/download}}</ref>

The {{convert|300|mm|in|abbr=on}} fab was inaugurated by French president [[Jacques Chirac]], on 27 February 2003. It includes an R&D centre which focuses on developing new nanometric technology processes for 90-nm to 32-nm scale using {{convert|300|mm|in|abbr=on}} 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.<ref>{{cite web|access-date=2023-11-03 |date= |title=Crolles2 Alliance Facility Expansion, Crolles |publisher=semiconductor-technology.com |url=https://www.semiconductor-technology.com/projects/crolles/}}</ref> 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.

===Rousset, France===
Employing around 3,000 staff, [[Rousset, Bouches-du-Rhône|Rousset]] hosts several division headquarters including [[smartcard]]s, [[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]].<ref>{{cite web|access-date= 2023-11-03 |date=2023-04-18 |title=ST's Manufacturing Strategy – the Key to Business Success |publisher=eletimes.com |url=https://www.eletimes.com/sts-manufacturing-strategy-the-key-to-business-success}}</ref><ref>{{cite web|access-date=2023-11-03 |date= |title=STMicroelectronics Inaugurates New 8 in.-200mm- Wafer Fab in Rousset |publisher=wirelessdesignonline.com |url=https://www.wirelessdesignonline.com/doc/stmicroelectronics-inaugurates-new-8-in-200mm-0001 }}</ref>

The site opened in 1979 as a {{convert|100|mm|in|abbr=on}} [[Fab (semiconductors)|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 {{convert|100|mm|in|abbr=on|0}} [[Fab (semiconductors)|fab]] was upgraded into {{convert|130|mm|in|abbr=on|0}} and later {{convert|150|mm|in|abbr=on|0}} fab in 1996. It is now being shut down. The site also has a "Wafer Level Chip Scale Packaging" accreditation for eSIM ICs.<ref>{{cite web|access-date=2023-11-07 |date=2018-06-27 |title=ST Offers eSIMs at Wafer Level |publisher=eetimes.com |url=https://www.eetimes.com/st-offers-esims-at-wafer-level/}}</ref>
