A fully depleted lean channel transistor (DELTA) having a gate structure and vertical ultrathin SOI (silicon-on-insulator) structure with selective field oxide is reported. In the deep submicron region, selective oxidation is useful for achieving SOI isolation. It provides a high-quality crystal and a Si-SiO/sub 2/ interface as good as those of conventional bulk single-crystal devices. Using experiments and simulation, it was shown that the gate structure of DELTA has effective channel…
