ABSTRACT:
A semiconductor device, e.g. a photoelectric converter, comprises a semiconductor transistor having a semiconductor controlling electrode region of one conductivity type resettable at a desired stage, an element isolation region of the same conductivity type, and an insulated gate type switching transistor for making the controlling electrode region and the element isolation region electrically conductive with each other. The element isolation region is preferably formed by at least two impurity injections with lamination or superposition. A peripheral element may be provided in the same substrate simultaneously with the formation of the semiconductor transistor and the element isolation region.
