Freescale Semiconductor offers MEMS bulk micromachining. MEMS bulk micromachining involves a process whereby the single crystal silicon is etched to form three-dimensional MEMS devices. This is a subtractive process in which the silicon in the wafer is specifically removed using antisotropic chemistry. Using this bulk micromachining method, sensors such as piezoresistive pressure sensors have been manufactured in high volume.

Keller America is the world's largest independent manufacturer of media-isolated, piezoresistive pressure sensors. Keller sensors are produced in three basic configurations: gauge pressure sensors, absolute pressure sensors, and sealed gauge pressure sensors. Keller's designs cover a broad spectrum of applications, from medical vascular intervention systems to down hole oil tools.
