Patent ID: 8658513

Claim:
A method of manufacturing a lateral AC LED array, having a plurality of LEDs arranged in a series configuration, comprising: creating a device having a substrate, a buffer layer closest to the said substrate, a n-type layer disposed on said buffer layer, a multi-quantum well disposed on said n-type layer, and a p-type layer disposed on said multi-quantum well; etching a region of said p-type layer and said multi-quantum well, so as to expose said n-type layer in said etched regions, whereby said etched region separates said multi-quantum well and said p-type layer of a first LED from said multi-quantum well and said p-type layer of an adjacent second LED and said n-type layer is not separated between said first LED and said second LED; implanting ions into a first portion of said buffer layer and a first portion of said n-type layer of said first LED, which is exposed in said etched region, said first portion adjacent to said p-type layer and said multi-quantum well of said second LED to create a first implanted region; implanting ions into a second portion of said buffer layer and a first portion of of said p-type layer and said multi-quantum well of said second LED, to create a second implanted region, wherein said second portion is immediately adjacent to said first portion, wherein the second implanted region is created after creating the first implanted region; applying a p-contact electrically connected to said p-type layer of said second LED and a n-contact electrically connected to said exposed n-type layer of said first LED; and using an interconnection electrode to electrically connect said p-contact of said second LED and said n-contact of said first LED.
