Generalized guide for MOSFET miniaturization

Abstract

As MOSFET dimensions are reduced, lower voltages, shallower junctions, thinner oxides, and heavier doping help to maintain long-channel behavior. A simple, empirical relation has been found between these parameters and the minimum channel length for which long-channel subthreshold behavior will be observed. This approximate relation provides an estimate for MOSFET parameters not requiring reduction of all dimensions by the same scale factor.
