First IEEE CASS Summer School

Atomistic simulations on reliability
Dragica Vasileska

Abstract:

In state of the art devices, it is well known that quantum and Coulomb effects play significant role on the device operation. In this talk we illustrate that: (1) proper treatment of the short-range Coulomb interactions is needed, and (2) there are significant variations in device design parameters for devices fabricated on the same chip due to the presence of discrete dopant atoms at random locations within the channel of a conventional MOSFET device. The influence of unintentional dopants is also examined in both narrow wire SOI devices and FinFETs with a three-dimensional (3D) in-house Monte Carlo - Molecular Dynamics Device Simulator. Finally, fluctuations in the on-current due to charging and discharging of random traps is examined and simulated and a theoretical circuit level model that explains the on-current fluctuations of 45 nm channel length MOSFET devices is proposed and will be presented at the workshop.

Biography:

Dragica Vasileska received the B.S.E.E. (Diploma) and the M.S.E.E. Degree form the University Sts. Cyril and Methodius (Skopje, Republic of Macedonia) in 1985 and 1992, respectively, and a Ph.D. Degree from Arizona State University in 1995. From 1995 until 1997 she held a Faculty Research Associate position within the Center of Solid State Electronics Research at Arizona State University. In the fall of 1997 she joined the faculty of Electrical Engineering at Arizona State University. In 2002 she was promoted to Associate Professor and in 2007 to Full Professor. Her research interests include semiconductor device physics and semiconductor device modeling, with strong emphasis on quantum transport and Monte Carlo particle-based simulations. She is a Senior Member of IEEE and APS. Dr. Vasileska has published more than 140 journal publications, over 8 conference proceedings refereed papers, has given numerous invited talks and is a co-author on a book on Computational Electronics with Prof. S. M. Goodnick. She has many awards including the best student award from the School of Electrical Engineering in Skopje since its existence (1985, 1990). She is also a recipient of the 1998 NSF CAREER Award. Her students have won the best paper and the best poster award at the LDSD conference in Cancun, 2004.
