Abstract:

A continuous and explicit compact model of short-channel effects (SCEs) for undoped cylindrical Gate-All-Around (GAA) MOSFETs is presented in this paper. SCEs are implemented into an analytic and continuous drain-current model based on a surface potential approach. Results regarding I-V characteristics, for short-channel transistors, are compared to numerical simulations and validate our method in all operating regions.
