Method for manufacturing light emitting diode devices

摘要

A method for manufacturing LED devices is disclosed to manufacture vertical LED devices without removing nonconductive substrates. A conductive substrate is formed on the LED epitaxial layer of the nonconductive substrate to form a LED wafer by bonding or electroplating, which is further cut into a plurality of LED sticks with each space layer bonded between every two LED sticks. Secondly, the plurality of LED sticks and space layers are fixed by a fixture while type I semiconductor layer and active layer of the LED epitaxial layer of each LED stick are covered by each space layer. A transparent conductive layer is further formed thereon whereby to electrically connect with the type II semiconductor layer contrary to type I and are further formed with a plurality of electrodes thereon. Finally the said LED sticks are cut to a plurality of LED devices.
