Abstract:
1. A semiconductor light emitting device comprising: a substrate made of a group III-V nitride semiconductor; a first-conductivity-type layer formed on the substrate, the first-conductivity-type layer including a plurality of group III-V nitride semiconductor layers of first conductivity type; an active layer formed on the first-conductivity-type layer; and a second-conductivity-type layer formed on the active layer, the second-conductivity-type layer being made of a group III-V nitride semiconductor layer of second conductivity type; wherein the first-conductivity-type layer includes an intermediate layer made of Ga part of the first-conductivity-type layer, the active layer, and the second-conductivity-type layer form a mesa portion, and the part of the first-conductivity-type layer which forms the mesa portion is a part excepting at least the intermediate layer.
