AuthorTremere, Douglas A.
Biographical NotesDouglas A. Tremere was born in Sioux Falls, South Dakota, in 1932. He received a B.Sc. in chemistry from the South Dakota School of Mines and Technology in Rapid City, South Dakota (1954). He joined Shockley Semiconductor in 1958 and Fairchild Semiconductor in 1959 where he worked on new transistor wafer processing and GaAs research projects . A 1966 organization chart shows him as a Senior Engineer in the Exploratory Devices Section managed by C. Bittmann. From 1970 to 1972 he worked on MOS IC development at Qualidyne Corp. He joined Westinghouse Research Laboratories in 1972.
