Abstract:
1. A method for fabricating a light-emitting device, the method comprising: (a) sequentially forming a first compound semiconductor layer, an active layer, and a second compound semiconductor layer, for inducing light emission, on a high-resistant substrate; (b) forming a light-transmitting conductive layer on the second compound semiconductor layer; (c) forming at least a via hole by dry etching a part of the high-resistant substrate and the first compound semiconductor layer using a reaction gas comprising at least Cl wherein the depth of the via hole is shallower than a sum of the thickness of the high-resistant substrate and the first compound semiconductor layer; and (d) forming a light-shielding conductive layer to cover the exposed region of the first compound semiconductor layer, such that the light-shielding conductive layer reflects the light emitted from the active layer upwardly, wherein the dry etching of portions of the high-resistant substrate and the first compound semiconductor layer is performed in a single process.
