Abstract:
1. A semiconductor light emitting device comprising: a conductive substrate, a first electrode layer, an insulating layer, a second electrode layer, a second semiconductor layer, an active layer, and a first semiconductor layer which are sequentially stacked, and an electrode pad unit disposed on an upper surface of the second electrode layer, wherein the second electrode layer includes at least one region where a portion of an interface in contact with the second semiconductor layer is exposed, the first electrode layer penetrates the second electrode layer, the second semiconductor layer, and the active layer and is electrically connected to the first semiconductor layer by being extended to predetermined regions of the first semiconductor layer through a plurality of contact holes which penetrate the predetermined regions of the first semiconductor layer, the insulating layer insulates the conductive substrate and the first electrode layer from the second electrode layer, the second semiconductor layer and the active layer by being formed between the first electrode layer and the second electrode layer and on side surfaces of the contact holes.
