Abstract

A fully depleted lean channel transistor (DELTA) with its gate incorporated into a new vertical ultrathin silicon-on-insulator (SOI) structure is presented. In the deep-submicrometer region, selective oxidation produces and isolates an ultrathin SOI MOSFET that has high crystalline quality, as good as that of conventional bulk single-crystal devices. Experiments and three-dimensional simulations have shown that this new gate structure has effective channel control and that the vertical ultrathin SOI structure provides superior device characteristics: reduction in short-channel effects, minimized subthreshold swing, and high transconductance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
