Abstract
A semiconductor crystal having a recombination-inhibiting semiconductor layer of a second conductive type that is disposed in the vicinity of the surface between a base contact region and emitter regions and that separates the semiconductor surface having a large number of surface states from the portion that primarily conducts the positive hole electric current and the electron current. Recombination is inhibited, and the current amplification factor is thereby improved and the ON voltage reduced.
