A method of manufacturing an LED of high reflectivity includes forming a substrate; depositing an n-type GaN layer on the substrate; depositing an active layer on a first portion of the n-type GaN layer; attaching an n-type metal electrode to a second portion of the n-type GaN layer; depositing a p-type GaN layer on the active layer; forming a metal reflector on the p-type GaN layer; attaching a p-type metal electrode to the metal reflector; and attaching the p-type metal electrode and the n-type metal electrode to an epitaxial layer respectively, wherein the metal reflector comprises a transparent layer, an Ag layer, and an Au layer and wherein the transparent layer and the Ag layer are formed by annealing in a furnace, and the Au layer is subsequently coated on the Ag layer.
