ABSTRACT:
A semiconductor sensor having a semiconductor sensor chip with a diaphragm on which a bridge circuit is formed with piezoresistances has a resistor for adjusting an offset of the bridge circuit wherein an adjustment is done to equalize an output voltage of the sensor at the upper operating limit temperature to that at the lower operating limit temperature by trimming the resistor.
