Abstract
A transistor device includes a semiconductor substrate and a gate structure formed over the substrate. When fabricating the transistor device, at least one dielectric layer may be formed over ohmic contact structures of the transistor device, which may mitigate migration of material, such as metal, from the ohmic contact structures onto sensitive surfaces of the transistor device during subsequent fabrication processes. The transistor device may include one or more dielectric spacers, including at least one dielectric spacer disposed at a side wall of a gate channel through which gate structure contacts the substrate. The transistor device may include a field plate formed at least partially over the gate structure, the field plate having one or more stepped portions, which may improve linearity performance of the transistor device.
