March 31, 2010 - Hsinchu, Taiwan － Asia Pacific Microsystems, Inc. (APM) announces today that it has shipped over 2 million MEMS pressure sensor elements to a leading global automotive electronic company. APM provides MEMS foundry services for the piezoresistive sensor elements which are key components for the pressure sensor business. With intensive engineering development and product qualification work with this customer, the first production has been launched in May 2009, and so have the additional product families in early 2010. APM is shipping the sensor elements to this first tier customer’s plant for module assembly and calibration. Dr. YH Tsai, President of APM, commented,”We are really proud of passing the tough quality requirement of automotive industry and being a supplier to a leading automotive technology company. This qualification is a major recognition of APM’s advanced technology, superior quality and cost leadership.”

APM is also a key partner to the same customer for the MEMS pressure sensor development roadmap. Early collaboration between the customer’s design group and APM’s process experts facilitates the turn-key proto-type fabrication and a true “design for manufacturability” model. This type of relationship aids in launching cost efficient, high quality, and high yield products.

APM is a pure-play MEMS wafer foundry founded in 2001. It is one of the leading MEMS wafer foundry service providers with a 27,000 square foot 6-inch MEMS fab comprised of a broad range of MEMS fabrication capabilities. This combination of automotive grade quality, competitive price and high volume capacity makes APM especially attractive to both the automotive and consumer electronics industries. APM, an affiliated company of United Microelectronics Corporation, is ISO 9001, ISO14001 and TS16949 certified.
