Classification: CPC H | IPC H

Claim 8:
9. The semiconductor processing method of claim 1, wherein forming the group of LED structures on the substrate layer to form the patterned LED substrate comprises:
forming an n-doped layer on the substrate layer, wherein the n-doped layer is a gallium-and-nitrogen-containing material;
forming a multi-quantum-well (MQW) structure layer on the n-doped gallium-and-nitrogen-containing layer;
forming a p-doped layer on the MQW structure layer;
etching the n-doped layer, the MQW structure layer, and the p-doped layer to form an exposed portion of the n-doped layer and an exposed portion of the p-doped layer;
forming an n-pad of the contact pads on the exposed portion of the n-doped layer; and
forming a p-pad of the contact pads on the exposed portion of the p-doped layer.
