Abstract

See full text

A semiconductor element includes a collector contact layer of a high concentration N-type semiconductor layer. An N-type collector layer, a base layer, being a high concentration P-type semiconductor layer with a top surface, laminated on the collector layer, and an N-type emitter layer laminated on a part of the top surface, are laminated on the collector contact layer. A base-collector layer junction is located on a bonded surface, between the base layer and the collector layer. An inactive portion is located outside an outside end of a base electrode on the top surface, in a plan view. The inactive portion is formed by implanting ions of one of helium and argon into the first and second semiconductor layers. The inactive portion extends from the top surface to a position below the base-collector layer junction.
