Patent ID: 7723732

Claim:
A semiconductor light-emitting device comprising: a substrate having two main surfaces; and an active layer forming part, which is made of a compound semiconductor material, formed on one of the main surfaces, and includes an active layer, wherein: a plurality of holes, which pass through the active layer, are formed from the upper surface to the lower surface of the active layer forming part; a plurality of hollow parts, each of which corresponds to each hole, are provided between the active layer forming part and the substrate; the area of each hollow part is larger than that of the corresponding hole in plan view, and spreads on the lower surface of the active layer forming part, so as to expose a part of the lower surface of the active layer forming part, which overlaps the hollow part in plan view; light emitted from the active layer is reflected by a boundary surface between each of the hollow parts and the corresponding exposed part of the lower surface of the active layer forming part; a pad electrode is provided on the upper surface of the active layer forming part; and in plan view, the density of the hollow parts is higher in the vicinity of the pad electrode, in comparison with a peripheral area of the semiconductor light-emitting device.
