AMS AG History


In 1981, American Microsystems Inc. and Voestalpine AG formed a joint venture. The company was named Austria Mikro Systeme International Gesellschaft m.b.H. with HQs in Unterpremstaetten near Graz, Austria.


In 1983 the Austrian chancellor Fred Sinowatz officially opened the first 100mm Wafer factory in Austria, where production began with 300 employees.


In 1989, the first sales office was established in San Jose, California.


In 1991 ams was seen as one of the 25 fastest growing businesses in Europe.


In 1992, Semiconductor International Magazine, USA named Austria Mikro Systeme International Aktiengesellschaft as (the/a) Top Fab of 1992 in Europe.


In June 1993, Austria Mikro Systeme International Aktiengesellschaft was the first Semiconductor Company in Europe to go public at the at the Vienna stock exchange.


Austria Mikro Systeme International Aktiengesellschaft opened the first sales office in Asia in 1995 the company also received ISO 14001: 1996 and EMAS certification. In 1997, AMS achieved first successes in the area of Deep Submicron technologies.


In 1998, the NASAs "Deep Space 2" mission took off with 2 chips developed by Austria Mikro Systeme International Aktiengesellschaft and Boeing. These chips were designed to manage the power supply of the space probe. In the same year the company was accredited according to the American and German Automotive industry, QS 9000 and VDA 6.1 respectively.


In 1999, Austria Mikro Systeme International Aktiengesellschaft was designated preferred global foundry partner for CMOS and BiCMOS by Europe's leading design houses.


In 2000, the foundation stone for the first 200 mm wafer fab was laid at the headquarters in Unterpremstaetten, Austria. Also Austria Mikro Systeme International Aktiengesellschaft opened Design Centers in Rapperswil (Switzerland) and Pisa (Italy).


The new 200mm production line starts its trial run. At the same time a license agreement has been reached between austriamicrosystems AG and TSMC (Taiwan Semiconductor Manufacturing Company Ltd.), the largest global IC Foundry. After the successful trial run the new 200mm Wafer factory goes ahead with the mass production in 2002. New sales offices in Singapore were opened in the same year, furthermore an expansion of locations in Hong Kong, Japan and the USA was carried out.


Silicon Strategies listed austriamicrosystems as the only European company under the top ten 2003 Foundries worldwide. austriamicrosystems AG decided to continue its policy of expansion with new sales offices in South Korea, China (Suzhou), Finland and Sweden. Additionally, a design center for multimedia playback applications was set up in Bangalore, India.


2004 was the year austriamicrosystems AG found its way back to the stock exchange. Since 17 May that year austriamicrosystems AG is listed on the Swiss Stock exchange, short SIX, in Zürich.


In 2005 the standard products as well as the capacity of the 200mm Wafer factory were expanded to compensate for the shut down of the old 100mm factory which played a main part in the success of austriamicrosystems AG.


In 2006, the year of the 25th anniversary, a new test centre in the Philippines and a new design centre in India were built. The 200mm Wafer factory was also expanded further.


In 2007 austriamicrosystems AG stepped into new business segments in the form of a partnership with the micro motor manufacturer New Scale Technologies. In the same year the new cafeteria & conference centre (CCC) was built by the architect DI Tinchon.


AG reduced emissions and plans in the mid term to produce CO2-free. Nevertheless, austriamicrosystems AG reached revenues amounting to EUR 209.4 in 2010.


In 2011 austriamicrosystems acquired 100% of the shares in Texas Advanced Optoelectronic Solutions, Inc., ("TAOS") for about US$320 million (about EUR 220m). TAOS works in the area of light sensor technologies.


In May 2012 austriamicrosystems rebrands to "ams". The new brand name ams conjoins austriamicrosystems and the brand of TAOS, a supplier of intelligent lights sensors, acquired in 2011. Furthermore, ams AG acquired IDS Microchip AG in the same year.
