Patent ID: 8012774

Claim:
A method for fabricating a light-emitting diode (LED) structure, comprising: providing a semiconductor structure disposed on a metal substrate formed by at least one of electrochemical deposition, electroless chemical deposition, chemical vapor deposition (CVD), metal organic CVD (MOCVD), plasma enhanced CVD (PECVD), atomic layer deposition (ALD), physical vapor deposition (PVD), evaporation, or plasma spray, the semiconductor structure comprising: a p-type semiconductor adjacent the metal substrate; an active region coupled to the p-type semiconductor; and an n-type semiconductor coupled to the active region; depositing an n-contact on a surface of the n-type semiconductor; applying a temporary material above the n-contact; applying a wavelength-converting layer above at least a part of the n-type semiconductor, wherein the surface of the n-type semiconductor is roughened before applying the wavelength-converting layer by at least one of wet etching, dry etching, or photolithography with etching; removing the temporary material; and dicing the semiconductor structure and the metal substrate into separate LED structures.
