Jack Kilby, in full Jack St. Clair Kilby, (born Nov. 8, 1923, Jefferson City, Mo., U.S.âdied June 20, 2005, Dallas, Texas), American engineer and one of the inventors of the integrated circuit, a system of interconnected transistors on a single microchip.
By September 12, Kilby had built a working model (see the lower photo), and on February 6th, Texas Instruments filed a patent. Their first Solid Circuit the size of a pencil point (11-by-1.5-millimetres in size ), was shown off for the first time in March, 1960. The original integrated circuit of Jack Kilby. But over in California, another man had similar ideas. In January of 1959, Robert Noyce (see his biography) was working at a small startup companyâFairchild Semiconductor, which he and 7 of his colleagues established in 1957, leaving Shockley Semiconductor.
