theses. At the University of Florida
, he guided 10 doctoral theses in EE
. He has published about 280 journal articles and presented about 170 invited lectures and 60 contributed papers in China, Europe, Japan, Taiwan and in the United States on transistor physics, technology and evolution.
He wrote a three-volume textbook titled Fundamentals of Solid State Electronics (FSSE 1991), FSSE-Study Guide (1993) and FSSE-Solution Manual (1996). The latter included 100 pages of exposition on Transistor Reliability. FSSE was translated into Chinese in 2003.
, China. His father Pen-Tung Sah was an Academician of Academia Sinica
and the former president of Xiamen University
in the 1920s and 1930s. C.-T. Sah also had a brother Chih-Han Sah who was a mathematician
professor at the State University of New York at Stony Brook
.
C.-T. Sah received two B.S.
degrees in 1953 in Electrical Engineering and Engineering Physics from the University of Illinois and the M.S.
and Ph.D.
degrees from Stanford University
in 1954 and 1956, respectively. His doctoral thesis research was on traveling-wave tubes under the tutelage of Karl R. Spangenberg.
His industrial career in solid-state electronics began with William Shockley
in 1956 and continued at Fairchild Semiconductor
Corporation in Palo Alto from 1959 to 1964 until he became a professor of physics and electrical engineering at the University of Illinois for 25 years (1962–1988). Under the management of Gordon E. Moore, Victor H. Grinich and Robert N. Noyce at Fairchild, Sah directed a 64-member Fairchild Physics Department on the development of the first generation manufacturing technologies (oxidation, diffusion,epitaxy growth, and metal conductor thin film deposition) for volume production of silicon bipolar and MOS transistors and integrated circuit
technology including oxide masking for impurity diffusion, stable Si
MOS transistor, the CMOS
circuit, origin of the low-frequency noise, the MOS transistor model used in the first circuit simulator, thin film integrated resistance and Si epitaxy process for bipolar integrated circuit production.
He was the founding editor (1991) of the International Series on the Advances in Solid State Electronics and Technology (ASSET) which published three titles by invited authors (1990s) and is currently publishing six monographs (2007–2008) by invited authors on compact modelling of devices for computer aided design of integrated circuits, all with the World Scientific Publishing Company, Singapore
. His current (2007) research has been on MOS transistor models since he was drafted in October 2004 by his young colleagues to join them, after 40 years of absence subsequent to the 1964-Sah, 1965-Sah-Pao and 1966-Pao-Sah journal articles on MOS transistor models, in order to help further in the development of compact models for computer aided design of nanometer MOS integrated circuits.
For contributions in transistor physics and technology, he received the Browder H. Thomson best paper Prize (IRE-1962) for an author under 30, the J. J. Ebers Award
in Electron Devices (1981) and the Jack Morton Award (1989), all from the IEEE, the Franklin Institute
