ABSTRACT:
An FET having a high breakdown voltage comprises a P type semiconductor substrate (5), a plurality of pairs of source regions (S) and drain regions (D) each comprising N.sup.- impurity layers (3) formed in the substrate, gate electrodes (9) each formed through an insulating film over a region interposed between each of the source regions and each of the drain regions, N.sup.+ impurity diffused layers (4) formed, shifted by a constant dimension in the N.sup.- impurity diffused layers, a source terminal (7a) connecting a plurality of source regions and a drain terminal (7b) connecting a plurality of drain regions in the plurality of pairs such that a dimensional error caused by shifting is compensated for.
