Patent ID: 8440995

Claim:
A light emitting device, comprising: a light emitting structure including a first conductive semiconductor layer, an active layer on the first conductive semiconductor layer, a second conductive semiconductor layer on the active layer, a superlattice structure layer on the second conductive semiconductor layer, and a third conductive semiconductor layer on the superlattice structure layer; a light transmission electrode layer on the light emitting structure; a first electrode connected to the first conductive semiconductor layer; a second electrode electrically connected to the light transmission electrode layer on the light emitting structure; and an insulating layer that extends from a lower portion of the second electrode to an upper portion of the second conductive semiconductor layer, wherein a recess is formed under the second electrode and a portion of the light transmission electrode layer, wherein the recess is formed by removing portions of the third conductive semiconductor layer, the superlattice structure layer, and an upper portion of the second conductive semiconductor layer corresponding to the second electrode, and wherein the insulating layer is disposed in the recess so that the insulating layer contacts the second conductive semiconductor layer.
