Abstract:
1. A method of manufacturing a flip-chip light emitting diode, comprising: forming a light emitting diode epitaxy structure on a substrate, the light emitting diode epitaxy having a lower surface facing toward the substrate and an upper face opposite the lower surface; bonding a temporary substrate to the upper face of the light emitting diode epitaxy structure; removing the substrate to expose the lower surface of the light emitting diode epitaxy structure; bonding a transparent substrate to the lower surface; removing the temporary substrate; etching the light emitting diode epitaxy structure to partially remove the light emitting diode epitaxy structure to a depth, whereby the light emitting diode epitaxy structure includes a first upper surface and a second upper surface, the first upper surface and the second upper surface are of different doped types; forming a metal reflective layer on the first upper surface and the second upper surface of the light emitting diode epitaxy structure; and fabricating a first electrode and a second electrode on the metal reflective layer respectively, wherein the first upper surface of the light emitting diode epitaxy structure is underneath the first electrode and the second upper surface of the light emitting diode epitaxy structure is underneath the second electrode respectively.
