Chih-Tang Sah

Chih-Tang "Tom" Sah (; born in November 1932 in Beijing, China) is a Chinese-American electronics engineer and condensed matter physicist. He is best known for inventing CMOS (complementary MOS) logic with Frank Wanlass at Fairchild Semiconductor in 1963. CMOS is used in nearly all modern very large-scale integration (VLSI) semiconductor devices.

He was the Pittman Eminent Scholar and a Graduate Research Professor at the University of Florida from 1988 to 2010. He was a Professor of Physics and Professor of Electrical and Computer Engineering, emeritus, at the University of Illinois at Urbana-Champaign, where he taught for 26 years (1962-1988) and guided 40 students to the Ph.D. degree in electrical engineering and in physics and 34 MSEE theses. At the University of Florida, he guided 10 doctoral theses in EE. He has published more than 300 peer-reviewed journal articles with his graduate students and research associates, and presented about 200 invited lectures and 60 contributed papers in China, Europe, Japan, Taiwan and in the United States on transistor physics, technology and evolution.
