Abstract:
1. A semiconductor light emitting device comprising: a substrate; a first semiconductor layer on the substrate, wherein a side surface of a lateral periphery of the first semiconductor layer comprises a recessed portion; an active layer on the first semiconductor layer; a second conductive semiconductor layer on the active layer, wherein a portion of the recessed portion is recessed with respect to a side surface of a lateral periphery of the substrate and a side surface of a lateral periphery of the second conductive semiconductor layer; and an oxide layer disposed on a side surface of the recessed portion around the first semiconductor layer, wherein the oxide layer is provided between the substrate and the active layer, wherein a portion of a top surface of the oxide layer is in contact with a bottom surface of the active layer, wherein the oxide layer is on a top surface of the substrate, and wherein the first semiconductor layer comprises a buffer layer and a first conductive semiconductor layer.
