Patent ID: 8097532

Claim:
A method for manufacturing a semiconductor light emitting device having a p-side electrode and an n-side electrode, comprising: a semiconductor laminating step of laminating a plurality of nitride semiconductor layers to form a semiconductor laminated structure; and an electrode forming step of forming an electrode on at least one of the nitride semiconductor layers, the electrode forming step further including: a first metallic layer forming step of sequentially forming only an Ni layer and an Au layer constituting first metallic layers on a surface of a forming region of the n-side electrode, a first annealing step of annealing the first metallic layers in an atmosphere containing oxygen after the first metallic layer forming step, a second metallic layer forming step of sequentially forming a layer of a first metal and an Au layer constituting second metallic layers on a surface of the first metallic layers after the first annealing step, and a second annealing step of annealing the second metallic layers in a nitrogen atmosphere after the second metallic layer forming step.
