Abstract:
1. A method comprising: providing a semiconductor structure grown on a growth substrate, the semiconductor structure comprising a light emitting layer disposed between an n-type region and a p-type region, wherein a plurality of vias are etched through the p-type region and light emitting layer to expose portions of the n-type region, a plurality of metal n-contacts are disposed in the plurality of vias, and a metal p-contact is disposed on at least a portion of the p-type region disposed between two of the plurality of vias; attaching the semiconductor structure to a carrier by at least one interconnect; introducing an underfill in a cavity between the semiconductor structure and the carrier, wherein the underfill provides a rigid support for the semiconductor structure; and removing the growth substrate; wherein the underfill provides a rigid support for the semiconductor structure during removal of the growth substrate.
