Abstract:
1. A method of manufacturing a nitride semiconductor based light-emitting device comprising: an epitaxial multilayer formation process for stacking an N-type conductive nitride semiconductor layer, an active layer made of a semiconductor and a P-type conductive nitride semiconductor layer in this order on a semiconductor wafer; a metal film formation process for forming a first metal film on the P-type conductive nitride semiconductor layer; a film formation process for forming a film made of tungsten oxide on the first metal film; an annealing process for subjecting the semiconductor wafer after the film formation process to annealing; a film removing process for removing the film made of the tungsten oxide; and an electrode formation process for forming an electrode capable of achieving an ohmic contact with each of the N- and P-type conductive nitride semiconductor layers.
