TitleNall patent notebook (#106)
DescriptionThe single entry consists of a cross section drawing of “A micrologic semiconductor construction.”
AuthorNall, James R.
Biographical NotesJames R. Nall worked at the Tube Lab at the National Bureau of Standards/Harry Diamond Laboratories (also known as DOFL - Diamond Ordnance Fuse Laboratories), in 1957 where together with Jay Lathrop he pioneered the microminiaturization of solid-state circuits for the Department of Defense. In 1959 Nall joined Fairchild Semiconductor in Mountain View where he worked in the team led by Jay Last which developed the Micrologic family of planar integrated circuits. (Lathrop joined J. Kilby at Texas Instruments.) Based on Nall’s experience with photolithography at DOFL, he made important contributions to the project, including significant improvements in the step and repeat control of mask alignment equipment. In 1962 he co-found Molectro with Fairchild colleague D. Spittlehouse. They hired linear experts R. Widlar and D. Talbert from Fairchild. Molectro was acquired by National Semiconductor in 1965.
