Abstract:
1. A flip-chip light emitting diode (LED), comprising: a substrate; a p-region metal portion and an n-region metal portion over a surface of the substrate and separated from each other; a p-type epitaxial layer, an active layer, and an n-type epitaxial layer successively laminated over the substrate; a reflection layer disposed between the substrate and the p-type epitaxial layer; a current blocking layer disposed between the reflection layer and the p-type epitaxial layer, and positioned so as to prevent current from concentrating on an edge of the LED; an insulating protection layer, cladding a side wall of the LED and exposing a portion of a side wall of the n-type epitaxial layer; a P electrode coupling the reflection layer and the p-region metal portion of the substrate; and an N electrode coupling the side wall of the n-type epitaxial layer and the n-region metal portion of the substrate.
