Review: Semiconductor Piezoresistance for Microsystems
In this paper, we focus on piezoresistive pressure sensors, which typically measure deflection (deformation) of a thin circular or rectangular membrane (diaphragm) under an applied external pressure (Fig. 22). The membrane may be made from the same material as the wafer substrate (silicon, diamond, etc.) or CVDbased thin films (oxide, nitride, etc.).
