Innovative Layout Styles to Boost the Mosfet Electrical Performance

This paper describes how to potentiate the electrical performance of MOSFETs using non-conventional layout styles (rectangular gate geometry), without causing any extra burden to the current ICs manufacturing CMOS process. This layout approach is based on “drain-channel region-source interfaces engineering”, which is capable to add new effects to the MOSFET structure that contributes to improve the analog and digital electrical parameters of MOSFETs. Besides that, some of these new structures can enhance the transistor robustness in harsh environment (high temperature and radiation). Furthermore, as a first insight into exploration of this layout approach was applied in Multi-Gate MOSFETs (FinFET) by three-dimensional simulations and the results are very promising.
