Fok, Samuel M.Biographical Notes
Samuel (Sam) Fok (Ph.D.) worked for Shockley Semiconductor and joined Fairchild in February 1960. Initially he worked as a member of Jay Last’s Micrologic development team on isolation techniques and masking waxes. He developed an IR method to permit alignment of masks required for mechanical isolation from the rear of the wafer. Later he became a specialist in photo resist technology and developed many aspects of masking and photolithography. A Member of the Technical Staff reporting to H. Sello, Manager of the Materials and Processes Deptartment, circa 1966 he was responsible for building the in-house designed Mark III S R (step and repeat) Camera that was used for several years before comparable commercial machines were available. The 1967 organization chart shows him as a Member of the Technical Staff (MTS) reporting to Harry Sello, manager of the Materials and Processes Department. Fok filled 12 notebooks (8 patent books, 4 laboratory books) covering the decade from 1960 to 1970. They contain highly detailed records of his and other departmental activities within the company over this period.Publisher
