Numerical Exploration of Asymmetrical MOSFETs

Zhao Xiang Qiu


Ideal MOSFET is intrinsically symmetrical in source and drain, and all existing models describing MOSFETs are built with this structural symmetry.  There is increasing demand to exploit asymmetrical structures for performance optimization, such as asymmetric channel implant, LDD spacer process, and dual-material-gate MOSFETs.  In this project, MOSFETs with source/drain asymmetry will be explored using 2D numerical simulations in comparison with the symmetric counterpart.  Through the project, students will gain insights into transistor operation and modeling, and extend novel ideas for real applications.
