Jay T. Last begins the interview with a description of his family background and youth during the Great Depression and World War II. He reviews his undergraduate education at the University of Rochester and his graduate work in the von Hippel lab at Massachusetts Institute of Technology. There he completed doctoral research on the structure of barium titanate under an IBM fellowship. He was later invited to join Shockley Semiconductor Laboratory. He soon departed as one of the “Traitorous Eight” to form Fairchild Semiconductor, where he focused on the etching process for the mesa transistor. During this time, Last formed a close friendship with Jean A. Hoerni and began collecting African art. Last then supervised the creation of the integrated circuit. In 1961, he left Fairchild Semiconductor to join Teledyne to create more elaborate circuits. Teledyne mass-produced complex circuits for military, private corporations, and internal use. Last reviews the business climate of Silicon Valley that supported numerous spin-offs and discusses the dynamics of the American and international semiconductor industries. He then recounts his private investments, including that in Intel Corporation, and relates Gordon E. Moore's contributions to Intel Corporation. Last concludes with his personal involvement with the Archeological Conservancy, his African art collection, and publishing.
