Patent ID: 8658441

Claim:
A manufacturing method of a flip-chip nitride semiconductor light emitting element including: a nitride semiconductor light emitting element structure having an n-type nitride semiconductor layer and a p-type nitride semiconductor layer, which are laminated on a substrate, and an n-side electrode connecting surface of the n-type nitride semiconductor layer and a p-side electrode connecting surface of the p-type nitride semiconductor layer, the n-side electrode connecting surface and the p-side electrode connecting surface being formed on the same plane side of the substrate, an n-side electrode being connected to the n-side electrode connecting surface and a p-side electrode being connected to the p-side electrode connecting surface, the method comprising sequential steps of: a pad electrode layer forming step of forming a pad electrode layer that becomes the n-side pad electrode and the p-side pad electrode on the nitride semiconductor light emitting element structure; a resist pattern forming step of forming a resist pattern that coats regions where the n-side pad electrode and the p-side pad electrode are formed on the pad electrode layer; a pad electrode layer etching step of etching the pad electrode layer using the resist pattern as a mask to form the n-side pad electrode and the p-side pad electrode; a protective layer forming step of forming an insulating protective layer on a surface of the nitride semiconductor light emitting element structure and the resist pattern without removing the resist pattern; and a resist pattern removing step of removing the resist pattern.
