DocumentDescription
Describes projects related to the deposition of a wide variety of materials on silicon and semiconductor packaging components, including the production of oxide films on silicon by an ambient temperature process of anodic oxidization. Specific entries include; the formal project plan for anodic oxidization written by W. Waring (p. 4); disclosure of process for preparing magnetic films on silicon (p. 10); electro-less gold plating process (p. 18); CDC gate circuit project on a ceramic substrate – many samples of substrate material taped onto the pages of the book (pp. 22-42); pattern copper plating onto silicon (p. 45); plating wafers for upside-down mounting (flip-chip) (p. 56).Date

Duffek, Edward F.Biographical Notes
Edward F. Duffek received a B.S. (1952), M.S. (1956) and a Ph.D. (1957) in physical chemistry from Carnegie Institute of Technology in Pittsburgh, Pennsylvania. From 1957 to 1962 he was associated with the Metallurgical Department of Stanford Research Institute. He joined Fairchild circa 1962 as a Member of Technical Staff where he served as Group Leader in Electrochemistry working on electrochemistry of semiconductors, electroplating materials and process development until circa 1970.Publisher
