Patent ID: 8129711

Claim:
A nitride semiconductor light emitting device comprising: a substrate; an n-type semiconductor layer formed on the substrate; an active layer formed on the n-type semiconductor layer; a p-type semiconductor layer formed on the active layer; a transparent electrode formed on the p-type semiconductor layer; an n-type electrode formed on an exposed portion of the n-type semiconductor layer; and p-type bonding electrode formed on the transparent electrode, wherein at least one of the n-type semiconductor layer and the p-type semiconductor layer further includes a super lattice layer or a multi-stacked layer; and a V-shaped distortion structure is formed at least one portion of the active layer and the p-type semiconductor layer with reference to the n-type semiconductor layer, wherein the p-type nitride semiconductor layer comprises a hole injection layer formed on the active layer and a p-type contact layer formed on the hole injection layer, the V-shaped distortion structure is filled in an area between the p-type contact layer and the active layer, so that the lower surface of the p-type contact layer is flat, and the upper and lower surfaces of the active layer in the V-shaped distortion are bent towards the n-type nitride semiconductor layer, respectively.
