Claim:
1. A method for fabricating a III-nitride semiconductor switch, said method comprising: forming a III-nitride heterojunction; forming a field dielectric layer over said III-nitride heterojunction; etching a window inside said field dielectric; depositing a conductive body inside said window such that said conductive body fills said window and overlaps with a top surface of said field dielectric outside of said window; removing said conductive body that overlaps with said top surface of said field dielectric such that said conductive body is only disposed inside said window; and covering said top surface of said field dielectric and said conductive body inside said window with an etch stop layer, patterning said field dielectric to form another window therein, and depositing another conductive body inside said another window.
