Abstract of Interview

Kenneth E. Manchester was drafted after high school to serve in World War II and later attended San Jose State University. Manchester then completed a PhD in chemistry at Stanford University under the supervision of George S. Parks and worked as a postdoctoral fellow under Eric Hutchinson for three years. Manchester joined the surface chemistry group at Shell Development Company in 1955 and moved to Sprague Electric Company in 1962. At Sprague, he directed a research group that pioneered in the development of ion implantation, a key process in the manufacture of integrated circuits. Manchester later headed semiconductor research at Sprague before serving as director of quality assurance and reliability. He concludes the interview with thoughts on the need for chemists in semiconductor development.
