Patent ID: 7964889

Claim:
A nitride-based light-emitting device comprising: an n-type clad layer; a p-type clad layer; an active layer disposed between the n-type clad layer and the p-type clad layer; a transparent oxide layer disposed in direct contact with the p-type clad layer, and made of a transparent conductive oxide selected from the group consisting of a first transparent conductive oxide comprising gallium, indium, and oxygen as main components thereof, a second transparent conductive oxide comprising gallium, indium, tin, and oxygen as main components thereof and a third transparent conductive oxide comprising zinc, indium, tin, and oxygen as main components thereof; and a metal capping layer made of at least one selected from the group consisting of Ni, NixOy, Au, Pt, Pd, Mg, Cu, CuxOy, Zn, Ag, Sc, Co, CoxOy, Rh, Li, Be, Ca, Ru, Re, Ti, Ta, Na, and La on the transparent oxide layer.
