Abstract:
A semiconductor light-emitting element comprising:a semiconductor substrate;a light-emitting region grown on said semiconductor substrate and including an active layer having a p-n junction;a transparent electrode formed to cover the entire light-emitting surface of said light-emitting region and containing oxygen for a light output side electrode;a bonding electrode formed on said transparent electrode; anda current blocking layer formed under said transparent electrode and located immediately below said bonding electrode,wherein said current blocking layer consists of a semiconductor having a bandgap not less than an emission wavelength and containing Al, andsaid current blocking layer is located immediately below said bonding electrode with the center thereof matching the center of said bonding electrode, and a difference between diameters of said current blocking layer and bonding electrode is not less than three times a distance from said current blocking layer to said active layer.
