THE VALIDITY OF SCALING PRINCIPLES FOR FIELD-EFFECT TRANSISTORS
Abstract
The principles of scaling are described, including the convention of scaling some material property. In particular, semiconductor doping density is scaled inversely with linear dimensions. Electrical scaling exists, by definition, when electrical properties obey some prescribed proportionality to mechanical dimensions. The scaling of transmission lines, field-effect transistors,AND BIPOLAR TRANSISTORS IS EXAMINED. Transmission lines exhibit a delay time associated with series resistance and distributed capacitance which is a function of geometry but not of scale, on the order of 10 to the -10th power seconds for typical interconnections. Electrical scaling is valid for field-effect transistors, providing doping is scaled inversely with linear dimensions. For this convention, delay time scales linearly, and area power density is invariant with scale. Simple electrical scaling is invalid for bipolar transistors.
