Patent ID: 8071408

Claim:
A method of manufacturing a semiconductor light emitting element, comprising: a growing step of sequentially growing a first semiconductor layer of a first conductivity type, an active layer, and a second semiconductor layer of a second conductivity type on a growth substrate to form a layered structure; a separating step of separating said growth substrate from said layered structure to expose said first semiconductor layer; a depression forming step of performing wet etching on an exposed surface of said first semiconductor layer to form defect depressions deriving from crystal defects; an insulating layer forming step of forming an insulating layer on the exposed surface of said first semiconductor layer; a polishing step of polishing portions of said insulating layer and of said first semiconductor layer to flatten the surface of said first semiconductor layer; and a surface roughening step of performing wet etching on the surface of said first semiconductor layer to form protrusions deriving from a crystal structure.
