    Abstract: The present disclosure provides one embodiment of a method for fabricating light-emitting diode (LED) devices. The method includes forming a nano-mask layer on a first substrate, wherein the nano-mask layer has a randomly arranged grain pattern; growing a first epitaxy semiconductor layer in the first substrate, forming a nano-composite layer; growing a number of epitaxy semiconductor layers over the nano-composite layer; bonding a second substrate to the epitaxy semiconductor layers from a first side of the epitaxy semiconductor layers; applying a radiation energy to the nano-composite layer; and separating the first substrate from the epitaxy semiconductor layers from a second side of the epitaxy semiconductor layers.

    Abstract: A light-emitting diode structure includes an AuSn or AuIn-containing bonding layer over a substrate, a metal layer disposed over the bonding layer, a p-type doped gallium nitride (p-GaN) layer disposed over the metal layer, a n-type doped gallium nitride (n-GaN) layer approximate the p-GaN layer, a multiple quantum well structure disposed between the n-GaN and p-GaN layers, and a conductive contact disposed on the n-GaN layer. The n-GaN layer includes a rough surface with randomly distributed dips. The nano-sized dips have diameters distributed between about 100 nm and about 600 nm, have a dip density ranging from about 107 grains/cm2 to about 109 grains/cm2, and are spaced from each other with an average spacing S, average diameter D, and a ratio S/D that ranges between about 1.1 and about 1.5. The conductive contact is disposed on some of the nano-sized dips of the rough surface.

    Abstract: A Light-Emitting Diode (LED) is formed on a sapphire substrate that is removed from the LED by grinding and then etching the sapphire substrate. The sapphire substrate is ground first to a first specified thickness using a single abrasive or multiple abrasives. The remaining sapphire substrate is removed by dry etching or wet etching.
