Patent ID: 8405093

Claim:
A light emitting device including a light emitting structure, the light emitting structure comprising; a first conductive semiconductor layer, a second conductive semiconductor layer and an active layer between the first and second conductive semiconductor layers, and an intermediate layer interposed between the first conductive semiconductor layer and the second conductive semiconductor layer; wherein the first conductive semiconductor layer is an n-type semiconductor layer including GaN and doped with an n-type dopant; wherein the first conductive semiconductor layer includes a first n-type semiconductor layer and a second n-type semiconductor layer between the first n-type semiconductor layer and the active layer; wherein one surface of the first n-type semiconductor layer contacts the second n-type semiconductor layer; wherein the surface of the first n-type semiconductor layer coming in contact with the second n-type semiconductor layer is formed in an N-phase; and wherein the intermediate layer is an electron blocking layer.
