摘要: A method for manufacturing a light-emitting device includes steps of: providing a substrate comprising an upper surface and a lower surface opposite to the upper surface; processing the upper surface to be an uneven surface; forming a light-emitting structure on the upper surface of the substrate; and forming a hole through the substrate by radiating a coherent laser beam to the lower surface of the substrate for a predetermined time; wherein the band gap energy of the coherent laser beam is higher than the band gap energy of the substrate thereby the substrate is etched away by the laser beam.
