Patent ID: RE43725

Claim:
A method of fabricating an LED, the method comprising: growing a first GaN layer on a SiC substrate having the a same conductivity type as said substrate; growing a superlattice on said first GaN layer comprising a plurality of repeating sets (“periods”) of alternating layers selected from the group consisting of GaN, In x Ga 1-x N, where 0<x<1, and Al x In y Ga 1-x-y N, where x+y<1; growing a second GaN layer on said superlattice having the same conductivity type as said first GaN layer; growing a Group III nitride multiple quantum well on said superlattice second GaN layer ; growing a third GaN layer on said multiple quantum well; growing a contact structure on said third GaN layer having the opposite conductivity type from said SiC substrate and said first GaN layer; forming an a first ohmic contact to said SiC substrate at a first end of the LED ; and forming an a second ohmic contact to said contact structure at a second end of the LED that is opposite the first end of the LED .
