Claim Text:
1. A method for forming an electrode comprising: a photolithography step of forming an overhang-shaped resist on a semiconductor layered structure having a light-emitting layer that emits light by supplying electric power; a reflection layer forming step of forming a reflection layer on a surface on which the resist is formed; a barrier layer forming step of forming a barrier layer posterior to the reflection layer forming step; a pad layer forming step of forming a pad layer posterior to the barrier layer forming step; and a lift-off step of removing the resist posterior to the pad layer forming step, wherein a side surface coverage, that is a value obtained by dividing a side deposition rate by a deposition rate vertical to a substrate is 15% or more at the start point of the barrier layer forming step and is 0% at an end point of the barrier layer forming step and in the pad layer forming step.
