The microelectromechanical-systems market grew 9 percent last year, to $7 billion, with the top 30 MEMS makers logging a collective $5.6 billion in revenue and growing an average of 7 percent, according to market watcher Yole Développement (Paris). Nine companies tallied sales above $200 million. Hewlett-Packard displaced Texas Instruments as the top-ranked MEMS supplier in 2007 on the strength of its printer sales, which use MEMS inkjet heads, Yole said. Automotive applications continued to drive the MEMS market overall, but consumer products showed the fastest growth rate, with Analog Devices Inc. and STMicroelectronics each recording more than 20 percent growth, largely from accelerometer design wins in Nintendo's Wii (both ST and ADI) and Apple's iPhone (ST). Knowles Acoustics, with its silicon microphone, and Avago Technologies, with its film bulk acoustic resonator (FBAR), achieved the MEMS industry's fastest growth rates, each exceeding 35 percent.
