Abstract

PURPOSE:To accelerate an I<2>L circuit by commonly using a base and an emitter, the collector and the base of pnp type load transistor and a pnm switching transistor respectively with an n<3> buried layer as an emitter and using the collector of the pnm type switcing transistor as a Schottky metallic electrode. CONSTITUTION:When an n<+> type buried layer 2 is formed on a p type substrate 1, B is doped on the surface to form an n<-> type epitaxial layer 3, a p type layer 4 is formed thereon. Then, an n<-> type layer 3 is isolated by a p type layer 5, and an n<+> type layer 6 is formed thereon. An oxide film 7 is selectively removed and is anisotropically etched to form a V-shaped groove 8 reaching the buried layer 2, an oxide film 7B is formed on the groove surface, openings are perforated thereat to selectively form electrodes 9A-9E thereat to allow the electrodes 9D, 9E to form a Schottky junction. Since the npn type element can have a thin base and a large collector area in longitudinal shape, it provides high injection efficiency, and the pnm type element has high current amplification factor and low minority carrier storage. Accordingly, said I<2>L accelerates its operation and enhances its integrity.
