Abstract
A light emitting diode (LED) with metal reflector and the method of making the same is disclosed. The metal reflector is composed of at least two layers with one transparent conductive oxide layer and a highly reflective metal layer. The former allows most of the light passing through without absorption and then reflected back by the latter metal layer. The transparent conductive oxide layer can prevent the highly reflective metal layer from reaction with light emitting epi-layers even in high temperature to avoid the reflectivity degradation during the chip processing.
