Abstract:
1. A nitride semiconductor light-emitting element comprising: a nitride-based semiconductor substrate including an n-type dopant; a semiconductor multilayer structure, which is arranged on the principal surface of the semiconductor substrate and which includes a p-type region, an n-type region and an active layer sandwiched between the p- and n-type regions; an insulating film, which has been deposited on the upper surface of the semiconductor multilayer structure and which has an opening; a multilayer p-side electrode, which is arranged over the upper surface of the semiconductor multilayer structure and which makes contact with a portion of the p-type region of the semiconductor multilayer structure at the opening of the insulating film; and an n-side electrode, which is arranged on the back surface of the semiconductor substrate, wherein the multilayer p-side electrode includes a first p-side contact electrode layer that contacts with the portion of the p-type region and a second p-side interconnect electrode layer that has been stacked on the first p-side contact electrode layer, and wherein part of the first p-side contact electrode layer is exposed under the second p-side interconnect electrode layer.
