Patent ID: 8766287

Claim:
A light emitting device, comprising: a light emitting structure including a first conductive type semiconductor layer, an active layer, and a second conductive type semiconductor layer; a second electrode layer formed on an underside of the light emitting structure and electrically connected to the second conductive type semiconductor layer; a first electrode layer that passes through the second conductive type semiconductor layer and the active layer to contact with the first conductive type semiconductor layer; and an insulating layer formed between the second electrode layer and the first electrode layer, between the second conductive type semiconductor layer and the first electrode layer, and between the active layer and the first electrode layer, wherein the first electrode layer includes a first ohmic layer in contact with the first conductive type semiconductor layer and a first reflective layer that passes through the second conductive type semiconductor layer and the active layer to have an extension to the first conductive type semiconductor layer, the first ohmic layer and the first reflective layer being formed of different materials, and wherein the first reflective layer is in direct contact with the first conductive type semiconductor layer.
