Patent ID: 8866167

Claim:
A manufacturing method of a nitride semiconductor light emitting device comprising: forming an n-type nitride semiconductor layer on a substrate; forming an active layer on the n-type nitride semiconductor layer; and forming a p-type nitride semiconductor layer 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; wherein a V-shaped distortion structure is formed at the n-type semiconductor layer and the active layer and the p-type semiconductor layer, the V-shaped distortion structure adjacent to the n-type nitride semiconductor layer is sharper than the V-shaped distortion structure adjacent to the p-type nitride semiconductor layer, upper and lower surfaces of the active layer in the V-shaped distortion are bent towards the n-type nitride semiconductor layer, respectively, a lower surface of the p-type contact layer is flat, and a growth temperature of the p-type contact layer is higher than that of the n-type nitride semiconductor layer.
