Nitride optoelectronic devices with backside deposition

摘要

Nitride optoelectronic devices that have asymmetric double-sided structures and methods fabricating such structures are disclosed. Two n-type III-N layers are formed simultaneously over opposite sides of a substrate with substantially the same composition. Thereafter, a p-type III-N active layer is formed over one of the n-type III-N layers but not over the other.
