Career Highlights:
Le Coz joined the Rensselaer faculty fulltime
in 1988 as an assistant professor of Electrical, Computer, and Systems
Engineering. He was awarded a tenured associate professorship in
1995. Le Coz has been a visiting faculty member at LSI Logic Corporation
and at Sandia National Laboratories. He has been named a Digital
Equipment Corporation Fellow, a General Motors Scholar, and a Connecticut
State Scholar, and has received awards from the American Cyanamid
Company and PerkinElmer, Inc. Le Coz is a member of Tau Beta Pi,
Eta Kappa Nu, Sigma Xi, and the American Physical Society.
Research Areas:
Le Coz's research interests include transport
in semiconductor devices, equilibrium heterojunction theory, and
randomwalk algorithms for the physical design of ICs. His research
team is focusing on inventing and developing novel, stochastic RW
algorithms for solving electro and magnetostatic, electrodynamic,
and thermal equations in massively coupled electrical and optical
ICinterconnect structures. A principal goal of his research is
to maintain full parallelism, which will provide the efficient computational
enhancement needed to meet future modeling and simulation requirements
in highend digital ICs.
Team members are currently working on RW impulseresponse
extraction algorithms. They are developing novel impulseresponse,
momentextraction algorithms for both lumpedelement and continuumdomain
descriptions of IC interconnects. Their approach involves diagrammatic
expansion of a perturbation series (similar to that employed by
R.P. Feynman in theoretical physics) and subsequent stochastic RW
evaluation.
Another area of Le Coz's research is heatequation
solution in complex, ICinterconnect structures. The desire to improve
IC integration density has generated significant interest in 3D
(stackedchip) configurations. In fact, thermal management within
3D chips appears to present a serious technological challenge. A
related problem is the development of efficient algorithms and methodologies
for numerical analysis of heat transport within these complex conductordielectric
interconnect structures. Le Coz's team is developing a multiscale,
thermalanalysis methodology for 3D chip configurations. Their methodology
relies on a globallocal, floatingRW method for solving the heat
equation in complex material structures.
Le Coz's studies support three tasks of the Interconnect Focus Center
(IFC): Circuit & System Design and Modeling, Novel Communication
Mechanisms, and Materials and Processing. His research sponsors
include the Semiconductor Research Corporation (SRC), the Microelectronics
Advanced Research Corporation (MARCO), the Defense Advanced Research
Projects Agency (DARPA), and LSI Logic Corporation (LSI).
