Abstract:
1. A III-nitride semiconductor light-emitting device, comprising: a plurality of III-nitride semiconductor layers including a first III-nitride semiconductor layer having a first conductivity type, a second III-nitride semiconductor layer having a second conductivity type different from the first conductivity type, and an active layer disposed between the first III-nitride semiconductor layer and the second III-nitride semiconductor layer and generating light by recombination of electrons and holes; a bonding pad electrically connected to the plurality of III-nitride semiconductor layers; a buffer pad disposed on the bonding pad, the buffer pad partially exposing the bonding pad; and a protection film disposed over the buffer pad and the bonding pad in a manner that the protection film partially exposes the bonding pad for wire-bonding, wherein the buffer pad is made of a material which makes adhesion between the buffer pad and the protection film stronger than adhesion between the bonding pad and the protection film.
