Abstract
We present a new analytical mobility model for channel electrons in he avily-doped MOSFET's biased from weak to strong inversion suitable for implementation in device simulation codes. The model accounts for the two-dimensionality of the electron gas and for the effect of charge t rapping on the measurements and has been validated by comparing the th eoretical curves with an extensive set of mobility measurements perfor med on devices with channel doping ranging from 3.8 x 10(17) to 1.25 x 10(18) cm(-3) over a wide bias and temperature range (141-400 K).
