Patent ID: 8455914

Claim:
A light emitting device comprising: a second metal layer; a second conduction type semiconductor layer on the second metal layer; an active layer on the second conduction type semiconductor layer; a first conduction type semiconductor layer on the active layer; a first metal layer on the first conduction type semiconductor layer; an insulating layer being disposed on a peripheral portion of an upper surface of the second metal layer and being disposed under a lower surface of the second conduction type semiconductor layer; and a passivation layer on lateral surfaces of the insulating layer, the second conduction type semiconductor layer, the active layer and the first conduction type semiconductor layer, the passivation layer being on an upper surface of the second metal layer, wherein the insulating layer is disposed between the second metal layer and the second conduction type semiconductor layer at the peripheral portion of the upper surface of the second metal layer, wherein the upper surface of the second metal layer contacts to the lower surface of the second conduction type semiconductor layer at a central portion of the upper surface of the second metal layer, wherein a lateral surface of the insulating layer is adjacent to a lateral surface of the second metal layer, and wherein the insulating layer and the passivation layer are formed of a different material.
