Monolithic multi-functional integrated sensor and method for fabricating the same

摘要

A monolithic multi-functional integrated sensor and method for making the monolithic multi-functional integrated sensor. The monolithic multi-functional integrated sensor includes: a pressure sensor including a plurality of piezoresistors having resistance values which vary with a change in external pressure, the piezoresistors being disposed in a direction so as to be subject to a piezoresistive effect produced by the external pressure at or beyond a predetermined first level; and a temperature sensor including a resistor having a resistance value which varies with a change in temperature, the resistor being disposed in a direction so as to be subject to a piezoresistive effect produced by the external pressure below a predetermined second level.
