Summary:

In this paper, we present modeling results for InGaAs FinFETs using the industry standard compact model BSIM-CMG. We show that BSIM-CMG produces excellent fits to the measured I-V data of these devices. The difference seen in carrier mobility behavior of InGaAs FinFETs compared to silicon devices can be accounted for in the model. Furthermore, the calibrated model is used for performance projection in these devices. It is found that parasitic resistance and mobility degradation severely limit the performance of these devices
