Patent ID: 6938501

Claim:
A semiconductor dynamic quantity sensor comprising: a semiconductor substrate that has a diaphragm changing a shape thereof in accordance with an application of a dynamic quantity; a bridge circuit that has four gauge resistors formed on the semiconductor substrate, resistances of the four gauge resistors varying based on a stress with respect to changing the shape of the diaphragm, each of the four gauge resistors having a plurality of divisional gauge resistors; a pair of first output terminals connected to a pair of respective first midpoints between the four gauge resistors, a differential electric potential between the first output terminals being used as a sensor output; and a pair of second output terminals connected to a pair of respective second midpoints between the divisional gauge resistors, a differential electric potential between the second output terminals being used as a diagnostic output, wherein at least one of the first output terminals has a plurality of terminals connected to different positions of the respective first midpoints, and at least one of the second output terminals has a plurality of terminals connected to different positions of respective wiring patterns formed between the divisional gauge resistors.
