Claim 0:
1. A method for manufacturing a light emitting diode based display panel device, the method comprising:
providing at least one carrier wafer;
providing a first substrate having a first surface region;
forming a first release material overlying the first substrate;
forming a first gallium and nitrogen containing epitaxial material overlying the first surface region, the first gallium and nitrogen containing epitaxial material comprising at least an n-type gallium and nitrogen containing region, a light emitting gallium and nitrogen containing region configured to emit electromagnetic radiation at a first blue wavelength, and a p-type gallium and nitrogen containing region;
patterning the first gallium and nitrogen containing epitaxial material and forming mesas to form a first plurality of dice arranged in a first array, each die corresponding to at least one light emitting diode device and being arranged by a first pitch between adjacent die in the first array;
forming a first interface region overlying the first gallium and nitrogen containing epitaxial material, the first interface region comprising a metal, a semiconductor, a dielectric, an oxide, a glass, or a polymer;
subjecting the first release material to a first energy source to fully or partially remove the first release material, the first release material disposed between the first substrate and the first gallium and nitrogen containing epitaxial material;
bonding the first interface region to the at least one carrier wafer to form a first bonded structure, while maintaining the first release material fully or partially removed from the first bonded structure;
releasing at least a first fraction of the first plurality of dice provided on the first substrate to transfer the first fraction of the first plurality of dice to the at least one carrier wafer; wherein each pair of the transferred dice is configured with a second pitch between each pair of the transferred dice, the second pitch being equal to or greater than the first pitch; and
processing the at least one carrier wafer with at least the first fraction of the first plurality of dice to form the light emitting diode based display panel device operable at least at the first blue wavelength, the first blue wavelength having a range of range of about 420 nm to 480 nm.
