Abstract
One embodiment of the present invention provides a method for fabricating a high-power light-emitting diode (LED). The method includes etching grooves on a growth substrate, thereby forming mesas on the growth substrate. The method further includes fabricating indium gallium aluminum nitride (InGaAlN)-based LED multilayer structures on the mesas on the growth substrate, wherein a respective mesa supports a separate LED structure. In addition, the method includes bonding the multilayer structures to a conductive substrate. The method also includes removing the growth substrate. Furthermore, the method includes depositing a passivation layer and an electrode layer above the InGaAlN multilayer structures, wherein the passivation layer covers the sidewalls and bottom of the grooves. Moreover, the method includes creating conductive paths which couple a predetermined number of adjacent individual LEDs, thereby allowing the LEDs to share a common power supply and be powered simultaneously to form a high-power LED array.
