Abstract:
A semiconductor light-emitting device capable of improving current distribution, and a method for manufacturing the same is disclosed, wherein the semiconductor light-emitting device comprises a substrate; an N-type nitride semiconductor layer on the substrate; an active layer on the N-type nitride semiconductor layer; a P-type nitride semiconductor layer on the active layer; a groove in the P-type nitride semiconductor layer to form a predetermined pattern in the P-type nitride semiconductor layer; a light guide of transparent non-conductive material in the groove; and a transparent electrode layer on the P-type nitride semiconductor layer with the light guide.
