Technical Examples

In a piezo resistance type semiconductor device, a detecting sensitivity and output linearity are improved without increasing a forming region of a diaphragm. In a piezo resistance type semiconductor device having: a diaphragm; a supporting frame which is connected to an external periphery of the diaphragm, supports the diaphragm, and is formed relatively thicker than the diaphragm; and piezo resistance type stress detectors (4a, 4b) each for detecting a stress caused when the detector is distorted by deformation of the diaphragm by application of an acceleration or a pressure in the direction perpendicular to the diaphragm, at least a part of the diaphragm is cut off in a position where it is come into contact with the piezo resistance type stress detector and a groove is formed.
