Method for manufacturing light-emitting diode

A method for manufacturing a light-emitting diode, comprising:

• providing a temporary substrate;
• forming an illuminant epitaxial structure on the temporary substrate, wherein the illuminant epitaxial structure includes a first surface and a second surface on opposite sides of the illuminant epitaxial structure, and the temporary substrate contacts with the first surface of the illuminant epitaxial structure;
• forming a first transparent conductive layer on the second surface of the illuminant epitaxial structure;
• forming a metal substrate on the first transparent conductive layer;
• forming an adhesion layer on the metal substrate;
• providing a supporting substrate, wherein the supporting substrate is connected to the metal substrate by the adhesion layer;
• removing the temporary substrate, so as to expose the first surface of the illuminant epitaxial structure;
• forming a second transparent conductive layer on the first surface of the illuminant epitaxial structure, wherein the second transparent conductive layer is opposite to the first transparent conductive layer with regard to the illuminant epitaxial structure;
• and
• forming an electrode on a portion of the second transparent conductive layer.
