Filed: 1982-07-27
Abstract: PURPOSE:To enable yield on assembly with high efficiency without protecting a mesa side surface by an insulating film by a method wherein an oxidation protective film is formed to the surface of a mesa section, the state in which a section is projected from the outer circumference of the surface of the mesa section is brought, the projecting section is etched to an arbitrary shape in order to obtain an extraction electrode, and an electrode metal is formed. CONSTITUTION:An epitaxial growth layer 12 of the same conduction type as a semiconductor substrate 11 of low resistivity is formed onto the substrate, and a reverse conduction type diffusion layer 13 is formed to the growth layer 12. The oxidation protective film 15 is formed onto the diffusion layer 13, and the oxidation protective film 15 is etched through a chemical etching method to an arbitrary shape in order to obtain the extraction electrode. The oxidation protective film 15 is left through the chemical etching method in an arbitrary shape in order to prevent the reduction of yield during an assembly process. The electrode metal 16 is formed to the whole surface of the semiconductor substrate, and the whole side outer than the outer circumference of the oxidation protective film 15 are removed mechanically or chemically. The surface is mesa-etched while using the left electrode metal 16 as a mask. Even when the electrode metal drops to the side surface of the mesa section, a defective short circuit is removed completely during assembly because an insulating film is interposed on the lower side of a drop section.
