METHOD FOR PRODUCING LIGHT-EMITTING DEVICE

A sacrificial layer is formed on a region for forming the reflective electrode later on the p-type layer, Subsequently, a part of the p-type layer is dry etched to expose an n-type layer. Then, a resist layer having an opening is formed through photolithography on the p-type layer and the n-type layer exposed in the previous step. The opening has a pattern to enclose the sacrificial layer in a plan view. Next, the sacrificial layer is wet etched using a buffered hydrofluoric acid to remove the entire sacrifice layer. Subsequently, a reflective film is formed by sputtering on the p-type layer and the resist layer. Next, the resist layer is removed using a resist stripper, and only the reflective film on the p-type layer is left to form the reflective electrode.
