Patent ID: 7825006

Claim:
A method for fabricating a high light extraction photonic device, comprising: growing a lift-off layer on a substrate, wherein said lift-off layer comprises a material from the group InGaN, AlInGaN and AlInGaAs; providing an epitaxial semiconductor device structure on said lift-off layer by growing thin doped layers suitable for a resonant cavity light emitting diode, comprising growing a first epitaxial semiconductor layer on said substrate and growing a second epitaxial semiconductor layer on said first epitaxial semiconductor layer, such that said first semiconductor layer is sandwiched between said lift-off layer and said second semiconductor layer, wherein said lift-off layer is sandwiched between said device structure and substrate, said epitaxial semiconductor structure comprising an emitter adapted to emit light in response to a bias; flip-chip mounting said device structure, lift-off layer and substrate on a submount such that said epitaxial semiconductor device structure is sandwiched between said submount and said lift-off layer, and separating said substrate from said device structure.
