Patent ID: 7973330

Claim:
A substrate-free light emitting diode (LED), comprising: an epitaxy layer, comprising: a first type doped semiconductor layer having a first surface and a second surface, wherein the first type doped semiconductor layer comprises a first contact layer and a first cladding layer disposed on the first contact layer; a light emitting layer, disposed on the first surface of the first type doped semiconductor layer and exposing a portion of the first surface of the first type doped semiconductor layer; and a second type doped semiconductor layer, disposed on the light emitting layer, wherein the second surface of the first type doped semiconductor layer is exposed and serves as an outer surface of the substrate-free LED; and a conductive supporting layer having high reflectivity for an emitted light of the light emitting layer, disposed on the second type doped semiconductor layer; and a first contact pad, disposed on the first type doped semiconductor layer exposed by the light emitting layer and electrically connected to the first type doped semiconductor layer.
