PIEZORESISTIVE SENSOR WITH EPI-POCKET ISOLATION

摘要

A semiconductor sensor with epi-pocket isolation is described. In one embodiment, the semiconductor sensor comprises a deformable member which includes a first silicon region of a first conductivity type and a second silicon region of a second conductivity type surrounding the first silicon region. The semiconductor sensor further comprises a stress-sensitive diffused resistive element disposed on the deformable member in the first silicon region.
