Abstract
A method is provided for obtaining one or more Light Emitting Diode (LED) devices reconstituted over a carrier substrate. The method includes providing a silicon-based semiconductor substrate as the carrier substrate; providing, per each of the one or more LED devices, a compound semiconductor stack including an LED layer; applying a SiCN layer to the stack and the substrate, respectively; bonding the stack to the substrate, wherein the SiCN layer applied to the stack and the SiCN layer applied to the substrate are contacted; and annealing, after bonding, the bonded stack and substrate at a temperature equal to or higher than a processing temperature for completing the LED device from the stack, wherein said temperatures are at least 400° C. A semiconductor structure including the one or more LED devices reconstituted over a carrier substrate is also provided.
