Description
Jay Last's Micrologic development team, including Sam Fok, Isy Hass, Lionel Kattner, and Jim Nall, began to work on the flip-flop project in September 1959. The sketch of the metal mask interconnect pattern for the first flip-flop device shown on the attached pdf is taken from Lionel Kattner's notebook dated 12.22.59. The active area of this four transistor flip-flip measured 28 by 34 mils. The first functional physically-isolated integrated circuit based on this design was made on May 26, 1960. Donated by Lionel Kattner. 1 scanned page.

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.
