Abstract:
1. A method of fabricating a III-nitride semiconductor device, comprising: forming a III-nitride growth inhibitor body over a surface of a substrate; selectively removing portions of said III-nitride growth inhibitor body to expose portions of said substrate to serve as a III-nitride growth surface; forming a trench around at least one of said exposed portions, said trench extending below said III-nitride growth surface; filling said trench, a top surface of said filled trench generally coplanar with and laterally extending said III-nitride growth surface; and growing a III-nitride semiconductor body over at least one of said exposed portions, said III-nitride semiconductor body being surrounded by said III-nitride growth inhibitor body; wherein said III-nitride growth inhibitor body defines the outer boundary of said III-nitride semiconductor device.
