Chih-Tang Sah ( Chinese  薩 支 唐 , Pinyin Sà Zhītáng , called Tom Sah, born November 10, 1932 in Beijing ) is a Chinese-American physicist and electrical engineer .

life and work

Sah is the son of the physicist and former president of Xiamen University (and a member of Academia Sinica) Pen-Tung Sah . Sah studied electrical engineering and physical engineering ( Bachelor of Science , 1953) at the University of Illinois at Urbana-Champaign (UIUC) and Stanford University ( Master of Science , 1954), where he received his doctorate in 1956 under Karl Spangenberg (on traveling wave tubes ). He then went to the developing microelectronics industry in California to William B. Shockley and in 1959 to Fairchild Semiconductor in Palo Alto (founded by discontented former employees of Shockley's company such as Gordon Moore and Robert Noyce ), where he was until 1965 and headed the physics department. As early as 1962/63 he taught at the UIUC, where he became Professor of Physics and Electrical Engineering in 1964. In 1988 he retired and moved to the University of Florida .

At Shockley, he was the author of a classic work on electron-hole recombination in pn junctions with Robert Noyce and Shockley in 1957 and in 1959 on a fundamental process technology - planar technology , invented by Jean Hoerni - for the later manufacture of the first integrated circuits . At Fairchild, he led technology development for the first generation of industrial manufacturing of MOS transistors and integrated circuits. At Fairchild, CMOS technology was invented by Frank Wanlass in 1963 . At that time, Sah also developed MOS transistor models (which were used in the SPICE software ).

He is the author and co-author of over 250 scientific articles and has had around 50 doctoral students.

He was the founding editor of Advances in Solid State Electronics and Technology (ASSET) at World Scientific in 1991 .

He has received numerous prizes, including the JJ Ebers Award and the Jack Morton Award from the IEEE (1969) and the Certificate of Merit from the Franklin Institute . He holds honorary doctorates from Chiaotung University in Taiwan and Katholieke Universiteit Leuven and is an honorary professor from the universities of Tsinghua , Beijing and Xiamen in China. He is a Fellow of the IEEE, the American Physical Society , the Franklin Institute and the American Association for the Advancement of Science , the National Academy of Engineering , the Chinese Academy of Sciences in Beijing, and the Academia Sinica in Taiwan. In 1998 he received the Semiconductor Industry Association's University Research Award.

His brother Chih-Han Sah (1934-1997) was a math professor at the State University of New York at Stony Brook .
