Abstract

A substrate-free LED device is provided. The LED device comprises a substrate, an epitaxial layer disposed on the substrate, a first electrode disposed on a portion of the epitaxial layer, a second electrode disposed on another portion of the epitaxial layer, and a protection layer, disposed over the epitaxial layer. It is noted that in the LED device, the substrate comprises, for example but not limited to, high heat-sink substrate, and the protection layer comprises, for example but not limited to, high heat-sink, high transparent material.
