Multilayer ohmic contact for P-type semiconductor and method of making same.

摘要

An ohmically conductive contact for a thin film p-type semiconductor compound formed of at least one of the metal elements of Class IIB of the Periodic Table of Elements and at least one of the non-metal elements of Class VIA of the Periodic Table of Elements comprises a first layer of copper (14) contiguous with said p-type semiconductor compound (13) and having a layer thickness of from about 5 Angstroms to about 50 Angstroms and a second layer (15) thereon comprising at least a second conductive metal. The layer (14) forms a stable ohmic contact with film (13) and layers (14) and (15) form a stable current collector.
