Abstract :
An explicit charge-based compact model for lightly doped FinFETs is proposed. This design-oriented model is valid and continuous in all operating regimes (subthreshold, linear, and saturation) for channel lengths (L) down to 25 nm, Fin widths (W Si) down to 3 nm, and Fin heights (H Si) down to 50 nm with a single set of parameters. It takes short-channel effects, subthreshold slope degradation, drain-induced barrier lowering, drain saturation voltage with velocity saturation, channel length modulation, and quantum mechanical effects into account.
