Abstract:
1. A method of manufacturing a Light Emitting Diode (LED) device, comprising: (a) forming a buffer layer on a silicon substrate, and then forming a template layer on the buffer layer; (b) forming a superlattice structure directly on the template layer, wherein the superlattice structure includes a plurality of periods, and wherein each period of the superlattice structure includes an aluminum-gallium-nitride sublayer and a gallium-nitride sublayer; (c) forming an n-type layer over and directly on the superlattice structure; (d) forming an active layer over the n-type layer, wherein the active layer includes an amount of indium; (e) forming a p-type layer over the active layer such that the silicon substrate, the buffer layer, the template layer, the superlattice structure, the n-type layer, the active layer, and the p-type layer form a first structure; (f) bonding a conductive carrier to the first structure thereby forming a second structure; (g) removing the silicon substrate from the second structure thereby forming a third structure.
