Abstract:
1. A method of fabricating an electronic device, the method comprising: providing a III-nitride structure including a substrate, one or more III-nitride epitaxial layers, and a masking layer, wherein the III-nitride structure comprises: patterning the masking layer to form an etch mask; placing the III-nitride structure in a growth reactor; removing, using an in-situ etch in the growth reactor, a portion of the one or more III-nitride epitaxial layers corresponding to the etch mask to expose a regrowth region; regrowing, in the growth reactor, a III-nitride material in the regrowth region; removing the III-nitride structure from the growth reactor; forming a first contact structure to the substrate; and forming a second contact structure to the regrown III-nitride material.
