Lionel Kattner laboratory notebook pages from Fairchild Semiconductor
Copies of selected pages from Fairchild Semiconductor Research and Development laboratory notebooks kept by Lionel Kattner in 1959 and 1960. These pages relate to work involved in developing the first monolithic, planar-process integrated circuits, the Fairchild Micrologic family of circuits. In particular, the pages relate to developing techniques to create electric isolation between individual elements of a monolithic circuit. Initial work used physical isolation. Later work created “diffused barriers” by selectively doping certain areas of the semiconductor wafers.
