ABSTRACT:
A high-breakdown-voltage semiconductor device wherein a resistor body made of a P-type impurity region is disposed in a surface region of an N-type semiconductor body so as to form a resistor element, a P-type low doped region is disposed around the resistor body, and a plate layer which extends from a high potential electrode of the resistor body covers a main part of the P-type low doped region.
