Abstract

PURPOSE:To prevent the deterioration of a reverse withstanding voltage between the collector and the base of a semiconductor device when applying reverse voltage thereto and the increase of a leakage current thereof and to eliminate the occurrence of an improper mode thereof by forming a conductive ring region on the surface of a collector region through an insulating layer. CONSTITUTION:A p-type base region 2 is brought into contact with a collector region 1 made of an n-type semiconductor substrate, and an n-type emitter region 3 is formed further therein. Then, an insulating layer such as, for example, a silicon dioxide layer 4 is selectively etched to form electrodes 5-7. Thereafter, one or more concentric conductive ring-like regions 11 are so formed on the layer 4 as to surround the electrode 6. The region 11 thus formed isolates movable ions existed on the surface of the layer 4 via the region 11 when applying a reverse voltage thereto so as to eliminate the elongation of a space charge layer 9 to the vicinity of the electrode 7.
