Patent ID: 8889449

Claim:
A method for producing a group III nitride semiconductor light-emitting device having a part of a region of a light-emitting layer as a non-light-emitting region, the method comprising: sequentially laminating an n-type layer, a light-emitting layer and a p-type layer comprising a group III nitride semiconductor on a growth substrate; activating the p-type layer to p-type activation by heat treatment and then forming a p-contact electrode on the p-type layer; applying a metal paste comprising conductive metal particles dispersed in a solvent comprising a material containing hydrogen as a constituent element, to a desired region on the p-contact electrode; and solidifying the metal paste by heat treatment to form a part of a region of the p-type layer into a high resistance region, thereby forming a region overlapping a region having the metal paste applied thereto in a planar view, of the light-emitting layer into a non-light-emitting region.
