  • Abstract
    We present a novel Depletion-Mode Double-Gate (DMDG) FET. As opposed to the conventional, un-doped body, double-gate MOSFETs, the DMDG device confines the carriers to the center of the device for all applied gate voltages. The device exhibits high mobility due to the carrier confinement in the very low E-field region in the center of the device. Simulations show very high I/sub on//I/sub off/ ratios (NMOS=2.07 mA/25 nA, PMOS=1.02 mA/0.98 nA), excellent sub-threshold slopes and Fan-Out-Four (FO4) delays under 5.5 ps for 15 nm gate lengths.
