VTI makes consumer-grade MEMS

VTI Technologies Oy enters the consumer market for gyroscopes and silicon-MEMS oscillators.

"We are leveraging our experience in high-performance automotive MEMS gyroscopes to give our consumer gyros a competitive advantage," said Markku Hirvonen, president and CEO of VTI.

The company is known for its combo MEMS chips that combine an accelerometer die and a gyroscope die in the same package for automotive stability control. The chips propelled VTI Technologies into an over 50 percent market share for automotive stability control systems.

VTI says its consumer gyro will be smaller in size, have lower power consumption and be higher performance than other consumer gyroscopes which are not based on automotive-grade designs.

The company also says that its entry into the silicon MEMS timing chip market was motivated by its high-performance automotive-grade vibratory gyros in which the Coriolis force can be detected by a transducer as the plane of oscillation is rotated.

VTI maintains its own fab for its automotive and medical MEMS chips, where it pioneered what it calls "chip on MEMS," a process that flip-chips an ASIC with solder bumps onto a MEMS die. For its consumer MEMS gyros and oscillators, however, the company has transferred its chip-on-MEMS process to a Chinese foundry for mass production.
