Expert at a Glance

Robert Wallace, Ph.D. Erik Jonsson School of Engineering and Computer Science

Professor of Material Science, Electrical Engineering and Physics; Director of the UT Dallas Cleanroom Laboratory and the University's Electronic Materials Laboratory

Virtually every new semiconductor chip manufactured features an insulator technology co-invented by Dr. Wallace.

He is an expert on the science of the materials that go into building integrated circuits and the processes used to fabricate them.

His insulator technology is based on the element hafnium. Manufacturers can use it to produce chips that are smaller and more energy-efficient.

Wallace’s research interests include materials and integration issues for advanced devices. He holds 70 U.S. and international patents and has more than 130 articles in peer-reviewed journals.

From 1990 to 1999, Wallace worked for Texas Instruments in its Materials Science Laboratory. He received his Ph.D. in physics from the University of Pittsburgh.
