Patent ID: 8680549

Claim:
A semiconductor light-emitting device comprising: a substrate; a compound semiconductor layer formed on a first surface of said substrate; a metal electrode layer formed on said compound semiconductor layer, a thickness of said metal electrode layer being not less than 10 nm but not more than 50 nm, and said metal electrode layer comprising: a continuous metal part, any two point-positions in said continuous metal part being continuously connected without breaks; and a plurality of openings penetrating through said metal electrode layer and having a circle-equivalent diameter of not less than 10 nm but less than 5 μm; a light-extraction layer formed on said metal electrode layer and including a dielectric film, said light-extraction layer covering at least a portion of said continuous metal part and having a thickness of not less than 20 nm but not more than 120 nm; and a counter electrode formed on a second surface of said substrate.
