    摘要: Semiconductor devices, such as GaN HEMT and HFET devices, and methods of forming such devices, with a via that provides an electrical connection between a contact and a corresponding external contact pad. Embodiments include semiconductor devices with a via extending through a dielectric material to connect a gate to a corresponding external contact pad, and semiconductor devices with a via extending through a dielectric material to connect an Ohmic contact and a corresponding external contact pad. Embodiments also include semiconductor devices with a via connecting an external contact pad to a gate that is formed above a dielectric material.

    摘要: An enhancement-mode GaN transistor and a method of forming it. The enhancement-mode GaN transistor includes a substrate, transition layers, a buffer layer comprised of a III Nitride material, a barrier layer comprised of a III Nitride material, drain and source contacts, a gate III-V compound containing acceptor type dopant elements, and a gate metal, where the gate III-V compound and the gate metal are formed with a single photo mask process to be self-aligned and the bottom of the gate metal and the top of the gate compound have the same dimension. The enhancement mode GaN transistor may also have a field plate made of Ohmic metal, where a drain Ohmic metal, a source Ohmic metal, and the field plate are formed by a single photo mask process.
