Claim 16:
17. A method of fabricating an electronic device, the method comprising:
forming a buffer structure over a substrate;
forming an aluminum gallium nitride, aluminum nitride, indium aluminum nitride, or indium aluminum gallium nitride back barrier layer on the buffer structure;
forming a gallium nitride layer on the back barrier layer;
forming a hetero-epitaxy structure on the gallium nitride layer;
forming a doped gallium nitride structure of a hole injector on the hetero-epitaxy structure;
forming conductive structures, including forming:
a conductive structure of the hole injector partially over the doped gallium nitride structure;
conductive drain and source contacts of respective first and second transistors partially in the hetero-epitaxy structure; and
conductive gate contacts of the respective first and second transistors on the hetero-epitaxy structure.
