A distance between an end portion on a longer side closest to a thermal oxide film of the diffused layer and an end of the thermal oxide film is apart from each other by a predetermined value determined by stress distribution in the semiconductor region or by at least 4 .mu.m or more, the longitudinal direction of the diffused layer portion formed from the end of the thermal oxide film over to a stress distribution (gradient) forming region in the semiconductor region is parallel to the forming direction of the stress gradient, and resistance value distribution is formed parallel to the stress gradient in the diffused layer formed from the end of the thermal oxide film over to the stress distribution forming region in the semiconductor region.
