Abstract

A gate pad and a source pad are disposed on a semiconductor layer. The gate pad is disposed at the center portion of the semiconductor layer and has the shape of a circle centered on the center of the semiconductor layer as viewed in plan. The source pad is disposed so as to surround the gate pad, and has the shape of a circular ring centered on the center of the semiconductor layer as viewed in plan. A plurality of unit cells that compose a trench type MOSFET element are formed in the semiconductor layer.
