Integrated Circuit

Integration of multiple devices onto a single piece of semiconductor


In 1959 Jack Kilby of Texas Instruments received U.S. patent #3,138,743 for miniaturized electronic circuits and Robert Noyce of Fairchild Semiconductor received U.S. patent #2,981,877 for a silicon based integrated circuit. After several years of legal battles (up until 1966), the two companies decided to cross license each others patent and the IC industry was born.
The concept was to embed a number of transistors and other devices onto a single piece of silicon and to form the interconnections within the silicon itself.
