Patent ID: 8372669

Claim:
A method of manufacturing a light emitting device including a substrate, a first conductivity type nitride semiconductor layer, an active layer and a second conductivity type nitride semiconductor layer, the method comprising: forming a pattern having a plurality of convex portions on a surface of the substrate; and growing the first conductivity type nitride semiconductor layer on the substrate where the pattern is formed, wherein the forming a pattern on a surface of the substrate comprises forming the convex portions of the pattern such that a distance between a first convex portion and an adjacent one of the convex portions is different from a distance between a second convex portion and an adjacent one of the convex portions, wherein the first conductivity type nitride semiconductor layer has a locally protruded and depressed structure and the active layer has a three-dimensional geometric curved indentation corresponding to the locally protruded and depressed structure of the first conductive nitride semiconductor layer.
