Abstract

PURPOSE:To form an electrode pattern of an excellent superposing accuracy by forming an emitter size with reactive sputtering etching and by isolating an emitter electrode and a base electrode with an inverted pedestal structure of a nitriding film and an oxidized film. CONSTITUTION:An oxidized film 9 and a nitriding film 10 are formed on the surface of the semiconductor substrate 1 having a base layer 2. Then, the films 9 and 10 are etched with the same etching speed with hydrogen and Freon using a reactive sputtering device, and a window 11 is opened. Next, a polycrystalline Si film 6 containing the impurities to be used for the emitter region formation, is formed on the emitter contact window only, the impurities are pushed in by heat diffusion and an emitter layer 3 is formed. Next, the oxidized film on the surface of the layer 6 is removed, the film 9 under the film 10 is etched at the same time and an inverted pedestal structure is formed. Then, the emitter electrode 7 and the base electrode 8 are formed separately by sputtering an electrode metal on the substrate 1 from the vertical direction.
