TriQuint Semiconductor was a semiconductor company that designed, manufactured, and supplied high-performance RF modules, components and foundry services. The company was founded in 1985 in Beaverton, Oregon before moving to neighboring Hillsboro, Oregon. In February 2014, Greensboro, North Carolina-based RF Micro Devices and TriQuint announced a merger in which the new company would be Qorvo, Inc., with the merger completed on January 1, 2015.〔(【引用サイトリンク】url=http://www.triquint.com/newsroom/news/2014/rfmd-and-triquint-unveil-new-company-name-qorvo )〕 ==History== TriQuint Semiconductor began its life in the mid-1980s as a subsidiary of Tektronix. In 1985 the founders held a contest to come up with a name for the company. The winning entry paid homage to the gallium arsenide on which the company was founded. *Tri, from the Greek for “a prefix meaning three, thrice, threefold”, and quint, from the Latin for “a set or sequence of five” literally means 3-5. 3-5 refers to the location of the elements gallium and arsenic on the periodic table. The elements on the third and fifth columns of the periodic table, including nitrogen found in GaN, are known to have special conductive properties, great for producing compound semiconductors. Alan Patz was the first chief executive officer (CEO) of the company, serving from 1985 until 1991. In 1988, the core group working in the spin-off had to decide if they wanted to continue to work under Tektronix as the GaAs SBU or if they wanted to venture out on their own. This core group met in a hotel room at the Greenwood Inn in Beaverton, Oregon, and decided that they were going to use their experience to start the company that would eventually become TriQuint. In 1991, Gazelle Microcircuits, Gigabit Logic, and TriQuint all merged under the TriQuint name. The focus of the merged company was to produce components for mobile phones and other communication devices. On May 15, 2001, TriQuint and Sawtek Inc. announced that the two companies would merge.〔(TriQuint Press Release ), 2001-05-15. Retrieved on 2008-02-26.〕 Sawtek made products based on surface acoustic wave, and with the merger, TriQuint was able to incorporate their technology into its products. Patz left the CEO position in 1991 and Bert Moyer took over in May as the interim CEO, serving until September when Steve Sharp became the permanent leader of the company. In 2002, TriQuint acquired Infineon's GaAs semiconductor business as a part of a partnership between the two companies to create products together,〔(EE Times Asia Article ), 2002-05-03. Retrieved on 2008-03-06.〕 followed in late 2002, with the acquisition of a large portion of Agere Systems' optoelectronics business.〔(Compound Semiconductor Article ), 2002-10-22. Retrieved on 2008-03-07.〕 Also in 2002, Steve Sharp stepped down as CEO and Ralph Quinsey took over the position. TriQuint later sold the TriQuint Optoelectronics Business Unit created from this acquisition to CyOptics in 2005.〔(TriQuint Press Release ), 2005-04-14.

Retrieved on 2008-03-06.〕 TriQuint acquired the company to incorporate their work on bulk acoustic wave (BAW) products into their own work. On September 4, 2007, TriQuint completed the purchase of Peak Devices Inc. in order to incorporate their work on wide band bandwidth into its products.〔(TriQuint Press Release ), 2007-08-21.

Retrieved on 2008-08-27.〕 The company settled an investor lawsuit in 2009 over allegations of improper backdating of stock options. TriQuint agreed to pay nearly $3 million in plaintiff's attorneys fees to settle the case, but maintained the company did nothing wrong.〔 Also that year, the company began a patent dispute with rival Avago Technologies over acoustic wave filters, which was eventually settled in 2012 with the companies agreeing to cross-license patents between the companies. Overall, TriQuint spent around $20 million in the case.〔 For fiscal year 2010, the company's revenues had grown to $878.7 million, with about 25 percent of revenues coming from Apple Computer's contract manufacturer Foxconn. After several quarters of losses, the company posted a profit for its third quarter in 2013. TriQuint announced in February 2014 that it would merge with RF Micro Devices. The merger was completed on January 1, 2015, with the new company called Qorvo.〔 TriQuint had traded on the NASDAQ as TQNT prior to the merger. 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「TriQuint Semiconductor」の詳細全文を読む スポンサード リンク
