Patent ID: 8207003

Claim:
A method of manufacturing a gallium nitride-based compound semiconductor light-emitting device, in which a transparent conductive oxide film including a dopant is laminated on a p-type semiconductor layer of a gallium nitride-based compound semiconductor device, the method comprising the step of subjecting the transparent conductive oxide film to a laser annealing process using an excimer laser, and the step of subjecting the transparent conductive oxide film to a thermal annealing process at a range of temperature of 200 to 250° C., wherein energy density of the excimer laser in the laser annealing process falls within a range of 150 to 300 mJcm −2 , the p-type semiconductor layer comprises Ga, and the transparent conductive oxide film contains Ga in a concentration of 20 atoms % or below at a location within 1 nm from the interface between the transparent conductive oxide film and the p-type semiconductor layer, and the laser annealing process includes the step of forming unevenness on a surface of the transparent conductive oxide film using an excimer laser.
