Abstract:
1. A semiconductor light-emitting device, comprising: a conductive support structure; a semiconductor structure over the conductive support structure, the semiconductor structure having a first surface, a second surface, and two side surfaces in a vertical cross-section, wherein the semiconductor structure comprises a first-type semiconductor layer, an active layer, and a second-type semiconductor layer, wherein the second surface is opposite the first surface, wherein the first surface, relative to the second surface, is proximate to the conductive support structure, and wherein the second surface is a dominant light emitting surface; a first electrode electrically connected to the first-type semiconductor layer, wherein the first electrode is arranged between the conductive support structure and the first surface of the semiconductor structure; a second electrode electrically connected to the second-type semiconductor layer, wherein the second electrode is arranged over a part of the second surface; and a passivation layer contacting the second surface and the two side surfaces of the semiconductor structure, wherein the passivation layer has a first length in contact with the first-type semiconductor layer and a second length in contact with the second-type semiconductor layer, and wherein the second length is greater than the first length, and wherein the passivation layer has an open space on the second surface, and wherein the open space is aligned with the second electrode.
