It is commonly called ST, and it is Europe's largest semiconductor chip maker based on revenue. While STMicroelectronics corporate headquarters and the headquarters for EMEA region are based in Geneva, the holding company, STMicroelectronics N.V. is registered in Amsterdam, Netherlands. The company's US headquarters is in Coppell, Texas. Headquarters for the Asia-Pacific region is in Singapore whilst Japan and Korea operations are headquartered in Tokyo. The company headquarters for the Greater China region is in Shanghai. ==History== STMicroelectronics was formed in 1987 by the merger of semiconductor companies SGS Microelettronica (Società Generale Semiconduttori) of Italy and Thomson Semiconducteurs, the semiconductor arm of France's Thomson. At the time of the merger the company was known as SGS-THOMSON but took its current name in May 1998 following the withdrawal of Thomson SA as an owner. SGS Microelettronica and Thomson Semiconducteurs were both long-established semiconductor companies. 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 the Abruzzese city of l'Aquila, which in 1961 changed its name to ''Azienda Tecnica ed Elettronica del Sud'' and relocated its manufacturing plant to the outskirts of the Sicilian city of Catania * Società Generale Semiconduttori (founded in 1957 by Adriano Olivetti). Thomson Semiconducteurs was created in 1982 by the French government's widespread nationalisation of industries. It included: * the semiconductor activities of the French electronics company Thomson. * Mostek, a US company founded in 1969 by some ex-employees of Texas Instruments. * 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, founded in 1977. * SESCOSEM, founded in 1969. After its creation by merger in 1987, SGS-Thomson 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: * In 1989, British company Inmos known for its transputer microprocessors from parent Thorn EMI. * In 1994, Canada-based Nortel's semiconductor activities. * 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-based Genesis Microchip.〔http://www.st.com/stonline/press/news/year2007/c2554c.htm〕〔http://www.st.com/stonline/press/news/year2008/c2560c.htm〕 Genesis Microchip is known for their strength in video processing technology (Faroudja) and has design centres located in Santa Clara, Toronto, Taipei City, Taiwan R.O.C. and Bangalore. 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 Borsa Italiana in Milan. Buy-out of ''VLSI Vision Ltd''. In 2002, Motorola and TSMC joined ST and Philips in a new technology partnership. The Crolles2 Alliance was created with a new 12" wafer manufacturing facility located in Crolles (France). By 2005, STMicroelectronics was ranked fifth, behind Intel, Samsung, Texas Instruments and Toshiba, but ahead of Infineon, Renesas, NEC, NXP, and Freescale. The company was the largest European semiconductors supplier, ahead of Infineon and NXP (see Semiconductor sales leaders by year). Early in 2007, NXP (formerly Philips Semiconductors) and Freescale (formerly Motorola Semiconductors) decided to stop their participation in Crolles2 Alliance. Under the terms of the agreement the Alliance came to an end on December 31, 2007.〔By Anne-Francoise Pele, EE Times Asia. “(Freescale eases out of Crolles2 alliance ).” June 26, 2007. Retrieved July 15, 2013.〕 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. In 2011, STMicroelectronics announced the creation of a joint lab with Sant'Anna School of Advanced Studies. The lab will focus on research and innovation in bio-robotics, smart systems and microelectronics.〔Nicolas Mokhoff, EDN. "(ST Micro opens lab for humanoid robot research )." July 27, 2011. Retrieved July 27, 2011.〕 Past collaborations with Sant'Anna School of Advanced Studies included DustBot, a platform that integrated self-navigating "service robots" for waste collection.〔 ST Ericsson was a multinational manufacturer of wireless products and semiconductors, supplying to mobile device manufacturers.〔(【引用サイトリンク】 title=About us – General Information – ST-Ericsson )〕 ST-Ericsson was a 50/50 joint venture of Ericsson and STMicroelectronics established on 3 February 2009 and dissolved 2 August 2013. Headquartered in Geneva, Switzerland, it was a fabless company, outsourcing semiconductor manufacturing to foundry companies. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「STMicroelectronics」の詳細全文を読む スポンサード リンク
