Abstract
The main objective of present invention is to provide a manufacturing method of light emitting diode that utilizes metal diffusion bonding technology. AlInGaP light emitting diode epitaxial structure on a temporary substrate is bonded to a permanent substrate having a thermal expansion coefficient similar to that of the epitaxial structure, and then the temporary substrate is removed to produce an LED having a vertical structure and better performance. The other objective of the present invention is to provide a high performance LED that uses metal diffusion technology and wet chemical etching technology to roughen the LED surface in order to improve light extraction efficiency.
