TitleSnow patent notebook (#302)
AuthorSnow, Edward H.
Biographical NotesEdward H. Snow graduated from Dixie State College, located in St. George, Utah, in 1956 and received a Ph.D. in solid state physics from the University of Utah. He joined the Fairchild Semiconductor R&D Laboratory, located in Palo Alto in 1963. A 1966 R & D organization chart shows him as a Member of Technical Staff in the Surfaces-Device Theory section reporting to A. Grove. Together with Bruce Deal, Andy Grove, and C.T. Sah, he was an important contributor to the early understanding of the properties of metal-oxide-semiconductor (MOS) structures. He is credited with identifying sodium introduced by the heated tungsten filament used for electron beam aluminum evaporation as the major source of contamination. Ed Snow left in 1971 to co-found imaging company Reticon with Gene Weckler and John Rado where he served as Vice President until 1977.
