Abstract
A light-emitting diode (LED) and a method for manufacturing the same are described. The method for manufacturing the LED comprises the following steps. An illuminant epitaxial structure is provided, in which the illuminant epitaxial structure has a first surface and a second surface on opposite sides, and a substrate is deposed on the first surface of the illuminant epitaxial structure. A metal layer is formed on the second surface of the illuminant epitaxial structure. An anodic oxidization step is performed to oxidize the metal layer, so as to form a metal oxide layer. An etching step is performed to remove a portion of the metal oxide layer, so as to form a plurality of holes in the metal oxide layer.
