Patent ID: 8440996

Claim:
A semiconductor light emitting device comprising: an n-type semiconductor layer; an active layer formed on the n-type semiconductor layer; a p-type semiconductor layer formed on the active layer, the p-type semiconductor layer comprising a p-type cladding layer formed on the active layer and a p-type contact layer formed on the p-type cladding layer; an n-type electrode formed on the n-type semiconductor layer; and a p-type electrode formed on the p-type semiconductor layer, wherein a V-shaped distortion structure is formed at the n-type semiconductor layer and the active layer and the p-type semiconductor layer, 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, 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 bended toward the n-type semiconductor layer, respectively.
