Claim 18:
19. The method of claim 18, further comprising:
providing a third substrate having a third surface region;
forming a third release material overlying the third substrate;
forming a third epitaxial material overlying the third surface region, the third epitaxial material comprising at least an n-type gallium, indium, phosphorous, nitrogen, aluminum, or arsenic containing region; a gallium, indium, phosphorous, nitrogen, aluminum, or arsenic containing light emitting region configured to emit electromagnetic radiation at a third wavelength; and a p-type gallium, indium, phosphorous, nitrogen, aluminum, or arsenic containing region;
patterning the third epitaxial material and forming mesas to form a third plurality of dice arranged in a third array, each die corresponding to at least one light emitting diode device and being arranged by a fifth pitch between adjacent die in the third array;
forming a third interface region overlying the third epitaxial material;
subjecting the third release material to a third energy source to completely or partially remove the third release material;
bonding the third interface region to the at least one carrier wafer to form a third bonded structure, while maintaining the third release material completely or partially removed from the third bonded structure;
releasing at least a third fraction of the third plurality of dice provided on the third substrate to transfer the third fraction of the third plurality of dice to the at least one carrier wafer wherein each pair of the transferred dice is configured with a sixth pitch between each pair of the transferred dice, the sixth pitch being equal to or greater than the fifth pitch; and
processing the at least one carrier wafer with at least the first fraction of the first plurality of dice, the second fraction of the second plurality of dice, and the third fraction of the third plurality of dice to form the light emitting diode based display panel device operable at least at the first wavelength, the second wavelength, and the third wavelength;
wherein a repeating pattern of at least one red light emitting diode device operable at the third wavelength, at least one green light emitting diode device operable at the second wavelength, and at least one blue light emitting diode device operable at the first wavelength within the two dimensional matrix of light emitting diode devices forms pixels within the light emitting diode based display panel device.
