Modeling charge distribution on FinFET sidewalls

摘要

A method is provided for modeling charge distribution on FinFET sidewalls for estimating variability in device performance. The method includes: inputting structure parameters and simulation parameters for a FinFET structure; identifying a semiconductor-oxide interface in the structure, the interface including a plurality of atomic steps and a plurality of trapped charges; distributing charges at the interface; and performing device simulations and current-voltage analysis upon generating all samples of given number of devices.
