Abstract

PURPOSE:To form a low resistance electrode pattern by a method wherein an insulation detachment is performed on a polycrystalline wiring layer and the surface of a semiconductor substrate opening which is formed in self-matching using a stepped section and in that state of condition they are converted into a metal silicide. CONSTITUTION:The first silicon layer 201 is formed on one main surface of a semiconductor substrate. The layer 201 is formed into a polycrystalline silicon layer 203 through an intermediate of an insulation film 202 and a patterning is performed in self-matching way on the insulation film 202 using the polycrystalline film 203 as a mask. Then, metal is evaporated on the surface of said film 202 and a metal silicide is obtained by reacting it to silicon with heat treatment. After that, unnecessary metal on the insulation film is removed by performing an etching. Consequently, an electrical separation is maintained easily by increasing the thickness of the insulation film and this is especially useful in the formation of a base electrode and an emitter electrode of a bipolar transistor.
