Abstract:
1. A method for manufacturing a light emitting diode, comprising: forming an epitaxial layer structure comprising a light emitting region, a first epitaxial layer and a second epitaxial layer, wherein the second epitaxial layer is a p-type epitaxial layer; and depositing a first electrode and a second electrode on the epitaxial layer structure, the second electrode formed of a metal, the depositing comprising depositing the first electrode and the second electrode so that the first epitaxial layer is coupled between the first electrode and the second epitaxial layer, and the second epitaxial layer is between the second electrode and the first epitaxial layer, wherein the second epitaxial layer of the epitaxial layer structure has a root-means-square (RMS) roughness less than about 3 nm at a surface whereon the second electrode is formed.
