Abstract:
1. A method for fabricating a light emitting diode, comprising: forming a mask layer on a surface of a substrate; forming a conductive semiconductor layer on the mask layer, wherein the conductive semiconductor layer is formed on the surface of the substrate to have a side surface having a tilt angle with respect to the surface of the substrate, and wherein the tilt angle is configured to improve the light extraction efficiency of the diode; forming a semiconductor structure comprising a first-type semiconductor layer, an active layer, and a second-type semiconductor layer on the conductive semiconductor layer, wherein the conductive semiconductor layer is thicker than the semiconductor structure to serve as a template for growing the semiconductor structure; forming a first electrode on the semiconductor structure; forming a support layer on the first electrode; separating the substrate; and forming a second electrode on a surface of the conductive semiconductor layer.
