Cp. Auth et Jd. Plummer, SCALING THEORY FOR CYLINDRICAL, FULLY-DEPLETED, SURROUNDING-GATE MOSFETS, IEEE electron device letters, 18(2), 1997, pp. 74-76
We present a scaling theory for fully depleted, cylindrical MOSFET's,
This theory was derived from the cylindrical form of Poisson's equatio
n by assuming a parabolic potential in the radial direction, Numerical
device simulation data for subthreshold slope and DIBL were compared
to the model to validate the formula, By employing the scaling theory
a comparison with double-gate (DG) MOSFET's was carried out illustrati
ng an improvement of up to 40% in the minimum effective channel length
for the cylindrical device.
