Patent ID: 8536585

Claim:
A semi-conductor light emitting device comprising: an n-type ZnO substrate having a mounting surface; a light emission layer composed of a p-type GaN film and an n-type GaN film superimposed on said p-type GaN film, said light emission layer being superimposed on said n-type ZnO substrate with said p-type GaN film directly disposed on said mounting surface of said n-type ZnO substrate; an anode disposed directly on said mounting surface of said n-type ZnO substrate in an ohmic contact therewith and in a spaced relation from said light emission layer; and a cathode disposed on said n-type GaN film in an ohmic contact therewith, wherein: said anode and said cathode are of the same structure solely composed of a metallic material, each of said anode and said cathode is made of a metal laminate, and said anode is disposed directly on said mounting surface, and said cathode is disposed on said mounting surface through said light emission layer such that said p-type GaN film of said light emission layer is disposed directly on said mounting surface.
