Patent ID: 8243767

Claim:
A Vertical-Cavity Surface-Emitting Laser (VCSEL) device comprising: a substrate; a first semiconductor multi-layer film of a first conductive type formed on the substrate; an active layer; a second semiconductor multi-layer film of a second conductive type; an electrode pad electrically coupled to the second semiconductor multi-layer film; a post structure formed on the substrate, the post structure comprising a light emitter, and a wiring electrode extracted from the post structure, the electrode pad being coupled to the wiring electrode, the post structure being continuously surrounded by a first groove, and a second groove being continuously formed outside of the first groove with respect to the post structure and along with a dicing surface of the substrate, the first groove being formed along an outer periphery of the post structure, the wiring electrode, and the electrode pad, the first and second grooves being formed simultaneously to have the same depth respectively, a part of the post structure and the first groove being covered with a first insulating protection film, and the second groove being covered with a second insulating protection film separated from the first insulating protection film by a gap between the first groove and second groove.
