Frances Sarnat Hugle (August 13, 1927 – May 24, 1968) was an American scientist, engineer, and inventor who contributed to the understanding of
semiconductors
A semiconductor is a material which has an electrical conductivity value falling between that of a conductor, such as copper, and an insulator, such as glass. Its resistivity falls as its temperature rises; metals behave in the opposite way. ...

She also invented techniques, processes, and equipment for practical (high volume) fabrication of microscopic circuitry, integrated circuits, and microprocessors which are still in use today.
In 1962, Hugle co-founded Siliconix, one of

Chicago's south side, where she participated in many of the school's science clubs, including the chemistry, physics and biology clubs. In the spring of 1944, just before her graduation, she was selected to represent Hyde Park High in Chicago's Math Contest, in which she took first place.
After graduation, Sarnat attended the

Professional career
Hugle founded her first research company, Hyco Labs, in the mid-1940s and assumed the title of Director of Research. At Hyco Labs, she began the research and development of materials, processes and specialized equipment that would become the foundation of much of her future work. After marrying, the Hugles founded Stuart Laboratories, Inc.[Levine, Bernard; Guinther, Fred; February 24, 1997; ''The Package'', " Electronic News;" 43:2156; p. 36.] She worked at Stuart Laboratories from October 1949 until February 1951. They have four children, Margaret, Cheryl, David and Linda.
In March 1951, she went to work for Standard Electronics Research Corp., where she was cleared for "secret" work. She remained at Standard Electronics Research Corp until August 1952, and shortly thereafter obtained employment at the Baldwin Piano Company

s and may have been interested in "military and industrial electronics".[Rostky, George; October 30, 1997; ''A Radio and Silicon'', " Electronic Engineering Times;" Issue 978; pp. 113–120.] In 1959, both Hugle and her husband began work at Westinghouse Company in Pittsburgh. In 1960, at the request of Westinghouse, the Hugles moved to southern California to set up an astro-electronics laboratory.
In late 1961, the Hugles moved again, to the Laurelwood Subdivision in Santa Clara, in the San Francisco Bay Area, where the Hugles co-founded Siliconix in 1962. She developed Siliconix's first products and became its first Director of Research and Chief Engineer.[Carey, Pete; October 16, 2003; ''Silicon Valley Pioneer, Siliconix Founder, Dies at 76'', "]Mercury News

After leaving Siliconix in 1964, Hugle developed products for two more semiconductor companies that she co-founded with her husband. These were Stewart Warner Microcircuits, where she once again served as Director of Research and as Chief Engineer, and Hugle Industries.
Inventions and patents
Hugle was awarded at least seventeen patents, some posthumously. Amongst these, she has been credited with the invention of tape automated bonding (TAB) (a technology first put into commercial use by General Electric
