Abstract:
1. A light emitting diode (LED) structure comprising: LED layers, forming an LED die, comprising an n-type layer, an active layer, and a p-type layer epitaxially grown over a growth substrate, the LED layers forming a substantially rectangular surface; a first bonding metal on a back surface of the LED die electrically contacting at least one of the n-type layer and the p-type layer; a second bonding metal on a submount generally corresponding to the first bonding metal, the first bonding metal being bonded to the second bonding metal, with substantially no gaps between the first bonding metal and the second bonding metal; and a dielectric support structure formed on a bottom surface of the LED layers, facing the submount, prior to the first bonding metal being bonded to the second bonding metal, the support structure extending to at least two edges of the rectangular surface, such that at least portions of a perimeter of the rectangular surface are directly supported, in a direction normal to the rectangular surface along the perimeter, by the support structure, the second bonding metal, and the submount, wherein there is no growth substrate attached to the LED die after the LED die is bonded to the submount, and wherein there is no dispensed underfill between the submount and the LED layers to support the LED layers.
