Knowles, austriamicrosystems Team for Surface Mount Microphone Technology

12/6/2004 - Knowles Acoustics, the leading provider of microacoustic technology, and austriamicrosystems, one of the leading analog semiconductor designers and manufacturers, announced they have signed a strategic agreement detailing their shared vision for the advancement of surface mount microphone technology. As part of the agreement, austriamicrosystems will be a preferred silicon provider for Knowles Acoustics’ SiSonic microphone.

The SiSonicTM microphone takes advantage of semiconductor manufacturing processes that result in a robust microphone that yields a high degree of repeatability, stable acoustic performance, and flexibility for future design enhancements. SiSonic microphones are ideally suited for high volume applications associated with automatic pick-n-place surface mounting such as Cell Phones and PDAs.

"austriamicrosystems is one of the few semiconductor suppliers with unique capability to meet our demanding requirements," stated Jeff Niew, Vice President and General Manager of Knowles Acoustics. "With the record-breaking growth in consumer electronics products, securing partners who can accommodate this expansion is a critical factor in the success of our SiSonic microphone."

With over 20 years experience in chip design and fabrication, austriamicrosystems delivers highly competitive integrated analog and mixed signal solutions worldwide. austriamicrosystems is strongly positioned in the analog semiconductor market providing industry-leading design capabilities and well-established RF CMOS, high-voltage CMOS and BiCMOS processes.

"Knowles' global presence and emergence as the leading provider of MEMS acoustic components make them a strong partner," said John Heugle, Chief Executive Officer at austriamicrosystems. "The analog expertise and process know-how we offer and Knowles' acoustic heritage are a powerful combination. Together we are well-positioned to meet the worldwide surge in MEMS microphone technology."
