Patent ID: 10141478

Abstract:
A light emitting device including a substrate, a first conductive layer on the substrate, a second conductive layer on the first conductive layer, a metal layer on the second conductive layer, a light emitting structure on the metal layer and the second conductive layer, the light emitting structure including a first semiconductor layer containing AlGaN, an active layer, and a second semiconductor layer containing AlGaN, a first electrode on the light emitting structure, and a passivation layer disposed on a side surface of the light emitting structure. Further, the metal layer directly contacts with the light emitting structure, the second conductive layer directly contacts with the light emitting structure, a portion of the passivation layer is disposed on a top surface of the light emitting structure, a width of the second conductive layer greater than a width of the metal layer, and a distance between a top surface of the substrate and a bottom surface of the metal layer at a center portion of the metal layer is different from a distance between the top surface of the substrate and the bottom surface of the metal layer at a side portion of the metal layer.
