发明名称 Semiconductor light emitting device
摘要 A semiconductor light emitting device which can suppress the self-absorption of light propagating in a semiconductor film without hindering current spread therein. A reflecting film provided between a support substrate and the semiconductor film of the device includes reflecting electrodes that are in ohmic contact with the semiconductor film and that form current paths between the reflecting electrodes and surface electrodes in the semiconductor film. The reflecting electrodes are in contact with the semiconductor film at such positions that the surface electrodes, provided on the light-extraction-surface-side surface of the semiconductor film, are not over the reflecting electrodes along a direction of the thickness of the semiconductor film. The semiconductor film has reflecting-surface-side recesses made in regions containing regions directly under the surface electrodes and recessed toward the light-extraction-surface side, and reflecting-surface-side protrusions provided in regions containing parts of the semiconductor film in contact with the reflecting electrodes and bonded to the support substrate via the reflecting film.
