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. Both Ericsson and STMicroelectronics appointed four directors to the board with Hans Vestberg, President and CEO of Ericsson, serving as the chairman of the board and Carlo Bozotti, President and CEO of STMicroelectronics, as the vice-chairman. == History == ST-Ericsson was formed on 3 February 2009 when STMicroelectronics and Ericsson completed the merger of Ericsson Mobile Platforms and ST-NXP Wireless into a 50/50 joint venture. On 20 August 2008, STMicroelectronics and Ericsson announced their interest to merge their wireless semiconductor businesses. ST contributed its multimedia and connectivity products as well as their 2G/EDGE platform and 3G offering. Ericsson contributed its 3G and 3GPP Long Term Evolution (LTE) platform technology. The merger followed an existing strategic co-operation between Ericsson Mobile Platforms and ST-NXP Wireless. Ericsson also had a venture with Sony called Sony Ericsson during 2001–2012. On 11 December 2012, ST-Ericsson was on the brink of shutdown after its parent company STMicroelectronics decided to move out of the JV, citing loss of market share due to ST-Ericsson failing to attain Break-even. Since ST-Ericsson came into being in 2009, STMicroelectronics has slipped from 5 to 7 in global semiconductor firms' rakings. On 18 March 2013, the parent companies announced that the joint venture was to be closed down, with the parent companies taking over parts, but not all, of its operation and products.〔(【引用サイトリンク】 title=Ericsson and STMicroelectronics agree on strategic way forward for ST-Ericsson )〕 On 28 May 2013, ST-Ericsson announced that they would sell the assets and intellectual property rights for its mobile connectivity Global Navigation Satellite System (GNSS) to Intel for $90 million. On 5 August 2013 Ericsson (NASDAQ:ERIC) and STMicroelectronics (NYSE:STM) announced the closing of the transaction for the split up of ST-Ericsson. This follows the announcement the companies made on 18 March 2013 on the chosen strategic option for the future of the joint venture. Effective 2 August 2013 Ericsson has taken on the design, development and sales of the LTE multimode thin modem solutions, including 2G, 3G and 4G interoperability. ST has taken on the existing ST-Ericsson products, other than LTE multimode thin modems, and the GNSS (Global Navigation Satellite System) connectivity solution sold to a third party, and related business as well as certain assembly and test facilities. 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「ST-Ericsson」の詳細全文を読む スポンサード リンク
