Abstract: This letter reports a nitrogen ion implantation through silicon nitride passivation layer deposited on AlGaN/GaN on Si heterojunction structure. Employment of Si$_3$N$_4$ layer simplify HEMT fabrication process and helps to obtain high resistivity isolation due to the shift of implanted ions distribution towards the surface of semiconductor. This isolation process in combination with C-doped heterostructure buffer layer results in increased up to 650 V breakdown voltage.
Keywords: ion implantation, breakdown voltage, GaN, power transistor.
