On April 25, 1961, a patent was issued to Robert Noyce for the first microchip.
Robert Norton Noyce (December 12, 1927 – June 3, 1990), nicknamed “the Mayor of Silicon Valley,” was an American physicist who co-founded Fairchild Semiconductor in 1957 and Intel Corporation in 1968. He is also credited (along with Jack Kilby) with the realization of the first integrated circuit or microchip that fueled the personal computer revolution and gave Silicon Valley its name.
In July 1959, he filed for U.S. Patent 2,981,877 “Semiconductor Device and Lead Structure”, a type of integrated circuit. This independent effort was recorded only a few months after the key findings of inventor Jack Kilby. For his co-invention of the integrated circuit and its world-transforming impact, three presidents of the United States honored him.
