Abstract

PURPOSE:To obtain an I<2>L which prevents shortcircuit of collector and base employing impurity-containing polycrystalline layer for collector diffusing source and collector wiring, oxidizing and insulating the surface of the polycrystal and then forming a hole with a base electrode by a self-aligning process. CONSTITUTION:An N type high impurity density layer 2 and an N type epitaxial layer 3 are formed on a P type silicon substrate 1, is selectively oxidized, and a field oxide film 4 is formed. Then, with a dielectric layer 8 as a mask injector and base P type layer 5 is selectively diffused. Subsequently, an As-doped polycrystalline seilicon layer is selectively formed, and is oxidized on the surface. Then, the collector is diffused. Thereafter, an oxide film is etched, a hole is opened by self-aligning method only on the thin P type layer 5 of oxide film thick, and aluminum metal wiring 10 is formed thereon. Since the base electrode can the be thus formed by self- aligning method, it can prevent the shortcircuit of the base electrode and the collector region of the I<2>L.
