摘要:
There is provided a semiconductor light emitting device having a patterned substrate and a manufacturing method of the same. The semiconductor light emitting device includes a substrate; a first conductivity type nitride semiconductor layer, an active layer and a second conductivity type nitride semiconductor layer sequentially formed on the substrate, wherein the substrate is provided on a surface thereof with a pattern having a plurality of convex portions, wherein out of the plurality of convex portions of the pattern, 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.
