Abstract

Impurity concentration of a second semiconductor region is set such that when a predetermined reverse bias is applied to a heterojunction diode configured by a first semiconductor region and the second semiconductor region, a breakdown voltage at least in a heterojunction region other than outer peripheral ends of the heterojunction diode is a breakdown voltage of a semiconductor device.
