Abstract
The present invention relates to a method of fabricating a patterned substrate for fabricating a light emitting diode (LED), the method including forming an aluminum layer on a substrate, forming an anodic aluminum oxide (AAO) layer having a large number of holes formed therein by performing an anodizing treatment of the aluminum layer, partially etching a surface of the substrate using the aluminum layer with the large number of the holes as a shadow mask, thereby forming patterns, and removing the aluminum layer from the substrate.
