Dr. Xing Zhou of Nanyang Technological University

Compact Models (CMs) for circuit simulation have been at the heart of CAD tools for bridging circuit design and technology development over the past decades.  In this talk, we begin with an overview of the historical role of CMs and fundamental equations.  Evolution of MOSFET CMs, from bulk to SOI and FinFETs, is reviewed and their inter-relationships discussed.  Unification of CMs with the unified regional modeling (URM) approach is presented, together with model validation with numerical data and verification with experimental data.  Model extension to III-V HEMTs including 2-dimensional electron gas (2DEG) in multiple sub-bands and trap-charge effects is presented.

Biography:

Dr. Xing Zhou obtained his B.E. degree in electrical engineering from Tsinghua University in 1983, M.S. and Ph.D. degrees in electrical engineering from the University of Rochester in 1987 and 1990, respectively.  He has been with the School of Electrical and Electronic Engineering, Nanyang Technological University, Singapore since 1992.  His past research interests include Monte Carlo simulation of photocarrier transport and ultrafast phenomena as well as mixed-mode circuit simulation and CAD tool development.  His recent research mainly focuses on nanoscale CMOS compact model development.  His research group has been developing a unified core model for nanoscale bulk, SOI, double-gate, nanowire CMOS, as well as III-V HEMTs.  He has given more than 140 IEEE EDS distinguished lectures and invited talks at various universities as well as industry and research institutions.  He is the founding chair for the Workshop on Compact Modeling (WCM) in association with the NSTI Nanotechnology Conference since 2002.  Dr. Zhou was an editor for the IEEE Electron Device Letters (2007–2016), a guest Editor-in-Chief for the special issue of the IEEE Transactions on Electron Devices (Feb. 2014) on compact modeling of emerging devices, and a member of the Modeling & Simulation subcommittee for IEDM (2016, 2017).  He was an Elected Member-at-Large of EDS Board of Governors (2004–2009; 2011–2016) and served as Vice-President for Regions/Chapters (2013–2015).  He has been an EDS distinguished lecturer since 2000.
