ABSTRACT:
A method for manufacturing a vertical light emitting diode of the invention allows an easier process of individually separating chips. A light emitting structure is formed on a growth substrate having a plurality of device areas and at least one device isolation area. The light emitting structure has an n-type clad layer, an active layer and a p-type clad layer sequentially formed therein. Corresponding p-type electrodes are formed on the light emitting structure on the device areas. A glass substrate having through holes perforated therein is provided on the p-electrodes so that the through holes are disposed corresponding to the p-electrodes. Also, the through holes are plated with a metal material to form patterns of a plating layer on the p-electrodes. Then, the growth substrate is removed to form n-electrodes on the n-type clad layer. The glass substrate is removed via etching.
