Patent ID: 8753911

Claim:
A method of making an LED device, comprising: forming epitaxially a SiC or AlN layer on a substantially single crystal Si wafer; forming epitaxially a substantially single crystal diamond layer on the SiC or AlN layer; doping the diamond layer to form a conductive diamond layer; removing the Si wafer to expose the SiC or AlN layer opposite to the diamond layer; forming epitaxially a plurality of semiconductor layers on the SiC or AlN layer such that at least one of the semiconductive layers contacts the SiC or AlN layer; and coupling an n-type electrode to at least one of the semiconductor layers, such that the plurality of semiconductor layers is functionally located between the conductive diamond layer and the n-type electrode, and where the conductive diamond layer and the n-type electrode are arranged such that there is a substantially linear conductive pathway therebetween.
