Abstract
A light emitting diode (LED) and method of making the same are disclosed. The present invention uses a layer of transparent adhesive material to bond a transparent substrate and a LED epitaxial structure having a light-absorbing substrate. The light absorbing substrate is then removed to form a LED having a transparent substrate. By the use of the transparent substrate, the light emitting efficiency of the LED can be significantly improved.
