1. A method comprising:
- providing a multilayer stack including a substrate, a semiconductor layer, and a quantum well containing region;
etching at least a portion of the quantum well containing region to provide an etched multilayer stack including a plurality of free-standing mesas supported by the substrate;
bonding the etched multilayer stack including the plurality of free-standing mesas to a submount; and
removing the substrate, in part, by exposing the semiconductor layer to electromagnetic radiation to partially decompose the semiconductor layer, wherein the electromagnetic radiation includes an absorption wavelength of the semiconductor layer;
patterning a surface of at least one of the mesas; and
forming a light emitting device from the at least one of the mesaswherein at least one of the plurality of mesas is at least about 1 mm on a side.
