Abstract:
1. A semiconductor light-emitting device comprising: a semiconductor substrate containing an n-type impurity and being made of silicon carbide or a nitride semiconductor; an n-type semiconductor layer provided on a main surface of the semiconductor substrate; an active layer provided on the n-type semiconductor layer; a p-type semiconductor layer provided on the active layer; a p-electrode in contact with the p-type semiconductor layer; and an n-electrode in contact with a surface of the semiconductor substrate opposite from the main surface, wherein, the n-electrode includes a first n-electrode which covers the entire surface of the semiconductor substrate opposite from the main surface and a second n-electrode provided on the first n-electrode so as to expose at least a portion of a periphery of the first n-electrode.
