Abstract
A Fermi-FET, including but not limited to a tub-FET, a contoured-tub Fermi-FET or a short channel Fermi-FET includes a drain extension region of the same conductivity type as the drain region and a drain pocket implant region of opposite conductivity type from the drain region. The drain pocket implant region acts as a drain field stop to reduce or prevent drain-to-source field reach-through. Reduced low drain field threshold voltage, significantly reduced drain induced barrier lowering and reduced threshold dependence on channel length may be obtained, resulting in higher performance in short channels.
