Biographical Notes

Lionel Estes Kattner (1930 – 2011) received a degree in chemistry, physics and math from Southwestern University, located in Georgetown, Texas in 1951. After graduation he worked at the Hanford, Washington plant on the production of plutonium for nuclear weapons and later served as a nuclear officer in the United States Navy. In 1958 he joined Texas Instruments in Dallas as a product engineer on a germanium mesa transistor product line. In 1959 Kattner was recruited into Jay Last’s microelectronics group at Fairchild Semiconductor where he worked closely with I. Haas on the fabrication of Micrologic, the first planar integrated circuit family. With three other Fairchild employees, he co-founded Signetics Corporation in 1961. He resigned from Signetics in 1967 and spent two years at Amelco Semiconductor. From 1969 until his retirement Kattner was involved with various projects and startups, including real estate development, computers, computerized mapping, microwave communications and fiber optics.

This document includes the scan of a layout for the mask design of the first Micrologic Type "F" flip-flop (μLF), a photograph of an experimental metal version of one of the physically-isolated devices, and an overlay drawing showing how this metal pattern mapped onto the final layout. The originals of these items from circa 1960 were donated to the museum collection by Lionel Kattner, one of the engineers who worked on the project. A data sheet from 1962 shows the physical and electrical specifications of the device. Donated by Lionel Kattner. 5 scanned pages.
