Abstract

PURPOSE:To prevent the breaking of a stage of an electrode and the fusing of the electrode with drive by large currents by substantially forming the surface of a semiconductor layer and the surface of a protective film in the same plane. CONSTITUTION:A P type base region 11 and an N type emitter region 12 are shaped to an N type collector substrate 10 so that the surfaces are exposed, and a SiO2 film 14 is formed through thermal oxidation, using a nitride film 13 as a mask. The SiO2 film 14 is removed once, and SiO2 films 15 are shaped anew through thermal oxidation. In this case, the thickness of the SiO2 films is controlled so that the surface of the silicon substrate under the nitride film 13 and the surfaces of the SiO2 films 15 molded to sections except the nitride film section are the same height substantially. The nitride film 13 is removed, and an emitter-base electrode forming section is exposed. An aluminum electrode 16 is shaped. Accordingly, the aluminum electrode 16 is formed so as to be substantially extended on the same plane, and functions as an electrode having high reliability.
