Duffek patent notebook (#191)

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).
