Abstract:
1. A method of producing a Group III nitride compound semiconductor device, comprising: forming an n-type layer on a substrate; forming at least one layer including a light emitting layer on said n-type layer; forming a p-type layer doped with a p-type impurity on said at least one layer; etching a portion of said p-type layer, said at least one layer, and said n-type layer, said etching revealing an end surface of said at least one layer; forming a p-electrode on said p-type layer; forming an n-electrode on said portion of said n-type layer; irradiating said p-type layer with an electron beam to reduce resistance of said p-type layer; and acidizing at least said end surface of said at least one layer after said irradiating.
