### Abstract

There are two assumptions made in the derivation of the Fermi's Golden Rule: (1) it is assumed that the scattering is infrequent which allows us to impose the long time limit and arrive at the energy conserving delta function, and (2) collision duration time is assumed to be zero, which implies that the intra-collisional field effect is neglected. The assumption (1) basically means that collisional broadening of the states (CBS) is being ignored in many analyses of deep-submicrometer devices. But when is that assumption valid? This is the point we want to address here. For that purpose we investigate the effect of CBS on three different technologies of MOSFET devices with substrate doping densities equal to 10 ^{17}cm ^{-3}, 5×10 ^{17}cm ^{-3}, and 10 ^{18}cm ^{-3}.
