Biography Summary

Chettypalayam (Selva) Selvakumar is a Professor in the Department of Electrical and Computer Engineering at the University of Waterloo.

Professor Selvakumar’s research interests include bipolar and field effect devices modeling and experimental process technologies. His current interests lie in Silicon/Germanium (SiGe) Devices and low temperature and integrable IC technologies. On the modelling side, Professor Selvakumar’s efforts are concentrated on developing insightful analytical models and accurate D.C. and A.C. Device Models for Bipolar and Field Effect Devices over a wide range of temperatures. Efforts in process modeling are currently focussed on dopant diffusion in implantation-formed alloy semiconductors. Research interests on the experimental side are focused on integrable process technologies. Professor Selvakumar is also interested in silicon-on-insulator technologies and buried silicides for high performance IC technologies, sensors and optoelectronics.
