Abstract:
1. A semiconductor light emitting device, comprising: a conductive substrate; a light emitting structure having a second semiconductor layer, an active layer, and a first semiconductor layer sequentially disposed on the conductive substrate, the first semiconductor layer having first and second surfaces, the first surface being adjacent to the active layer and the second surface being opposite to the first surface; a second electrode layer including at least one exposed region formed by exposing a portion of an interface between the second electrode layer and the second semiconductor layer, the exposed region extending toward a side surface of the light emitting structure that is exposed outwardly of the light emitting structure; a first electrode layer penetrating the second electrode layer, the second semiconductor layer, and the active layer and being electrically connected to the first semiconductor layer by being extended toward the second surface of the first semiconductor layer through a plurality of contact holes penetrating predetermined regions of the first semiconductor layer, the first electrode layer being electrically connected to the conductive substrate by being in contact with the conductive substrate; an insulating layer electrically separating the first electrode layer from the second electrode layer, the second semiconductor layer, and the active layer by being disposed between the first electrode layer and the second electrode layer and on side surfaces of the contact holes; and an electrode pad portion disposed on the exposed region of the second electrode layer.
