Patent ID: 8299492

Claim:
A light-emitting device, comprising: a light-emitting structure layer including a first conductive layer, a light-emitting layer, and a second conductive layer sequentially stacked on a first side of a substrate; a plurality of seed layer patterns spaced apart each other in the first conductive layer; a plurality of first electrodes extending through the substrate, wherein each of the first electrodes extends from a second side of the substrate to each of the seed layer patterns, the second side opposing the first side; and a plurality of via holes extending in a direction from the second side of the substrate through the substrate to each of the seed layer patterns, wherein one of the first electrodes entirely fills each of the via holes, wherein the seed layer pattern is composed of a metal, and each of the plurality of first electrodes are filled from the seed layer pattern by filling the via hole using electroplating.
