The invention of integrated circuit by Jack Kilby

The first integrated circuit was conceived by Geoffrey W. A. Dummer, a radar scientist for the Royal Radar Establishment of the British Ministry of Defense. He published his idea in Washington, D.C., on May 7, 1952. But by 1956, he had still failed to build a successful circuit based on his model.

Integrated circuit was invented in 1958 by Jack Kilby. The device sparked the modern microelectronic revolution.

Kilby started his work with miniature electrical components at Centralab, where he developed transistor for hearing aids. He then took a research position with Texas Instruments and developed a working model of the integrated circuit. His idea evolved to fabricating all the components and the chip put of the same block of semiconductor material. His invention was patented in 1959.

Kilby applied this invention to a various industrial, military and commercial applications, including first pocket calculator, called Pocketronic.

In July 1959, Robert Noyce of Fairchild Semiconductor file d a patent for his conception of the integrated circuit. Jack Kilby filed a law suit for patent interference against Noyce and Fairchild and the case dragged on for years.

Today Noyce and Kilby are generally regarded as co-inventors of the integrated circuit, although Kilby alone was inducted into the Inventors’’ Hall of Fame. as the inventor.
