Abstract
A Fermi-FET includes a Fermi-tub region at a semiconductor substrate surface, wherein the Fermi-tub depth is bounded between a maximum tub depth and a minimum tub depth. The Fermi-tub depth is sufficiently deep to completely deplete the Fermi-tub region by the substrate tub junction at the threshold voltage of the field effect transistor, and is also sufficiently shallow to produce a closed inversion injection barrier between the source region and the drain region below the threshold voltage of the Fermi-FET. High saturation current and low leakage current are thereby produced simultaneously. Source and drain injector regions and a gate sidewall spacer may also be provided.
