Abstract:
1. A method of forming a vertical light-emitting device (LED) structure, comprising: (a) forming a buffering layer over a sapphire substrate; (b) forming a plurality of masks over said buffering layer, wherein said substrate, said buffering layer and said plurality of masks jointly form a substrate unit; (c) forming a multi-layer epitaxial structure over said plurality of masks, wherein said multi-layer epitaxial structure comprises an active layer; extracting said multi-layer epitaxial structure; (d) removing said remaining masks bonding with a bottom side of said multi-layer epitaxial structure after extracting; (e) coating a metal reflector over said bottom side of said multi-layer epitaxial structure; (f) bonding a conductive substrate to said metal reflector; and (g) disposing a p-electrode over an upper surface of said multi-layer structure and an n-electrode over a bottom side of said conductive substrate.
