Description

Jay Last made the first entry in his book on 1957-08-11. It was read and understood by Gordon Moore. He used the volume for recording product and process ideas and results of related experiments. Specific topics include a proposal for improved thermal conductivity of transistor packages (p. 1); method and test results for accurately controlled etching (p. 7); printing and etching of wax dots for masking (p. 30); the company’s first microwave diodes (p. 32); parametric amplifier diodes (p. 38); diode arrays using oxide masking (planar) techniques (p. 48); method of interconnecting multiple transistors on a ceramic plate with example of a DCTL flip-flop (p. 55); physical isolation of micrologic elements – the basis of the two patents below (p. 58-59); light emitting readout devices (p. 60). Last notes on page 69 that the detailed physical isolation process steps he employed are described in Kattner (107).

Biographical Notes

Jay T. Last was born in Butler, Pennsylvania, in 1929. He received a B.S. degree in Optics from the University of Rochester in 1951 and a Ph.D. in Physics from MIT in 1956. He was recruited by William Shockley as a member of the technical staff at Shockley Semiconductor Labs. In September 1957, Last was one of the group of eight who founded Fairchild Semiconductor. At Fairchild with Robert Noyce, Last built the first step-and-repeat camera in 1958, worked on the first commercial silicon planar transistors, and ran the R&D group that produced the first integrated circuits. Last co-founded the Amelco semiconductor division of Teledyne in 1961. From 1966 to 1974 he served as Vice President, Research and Development for Teledyne Corporation. After he left Teledyne Last became involved with a number of venture capital and philanthropic activities. He founded the Archaeological Conservancy, dedicated to saving American archaeological sites and started Hillcrest Press in 1982, publishing books dealing with California art, ethnic art, and the graphic arts.
