Patent ID: 7279347

Claim:
A method for manufacturing a light emitting device of a light-emitting device (LED), comprising: (a) forming a buffer layer over an upper side of a substrate, wherein said substrate comprises sapphire, silicon carbide (SiC) and gallium nitride (GaN); (b) forming an n-GaN based epitaxial layer over said buffer layer; (c) forming an MQW layer over said n-GaN based epitaxial layer, wherein said MQW active layer comprises a material so that said MQW active layer emits a light with a wavelength comprising 380 nm to 600 nm in response to an applied electric power on said light-emitting structure; (d) forming a p-type distributed Brag reflector (DBR) over said MQW active layer; (e) forming a p-GaN based layer over said p-type DBR, etching away a portion of said n-GaN based layer, said MQW active layer, said p-type DBR and said p-GaN based layer whereby said n-GaN based layer has an exposing region and disposing an n-type electrode over said exposing region and a p-type electrode over said remaining p-GaN based layer after said etching; and (f) coating a metal reflector over a bottom side of said substrate.
