Abstract
A light emitting diode and the method of the same are provided. The light emitting diode includes a light emitting structure and a metal reflective layer. The light emitting structure includes two semiconductor layers and an active layer. Oxide elements are added into the metal reflective layer to improve the adhesion between the reflective layer and the light emitting structure. Additionally, a transparent contact layer can be formed between the light emitting structure and the reflective layer in order to enhance the luminance efficiency.
