Jack KilbyImplementing a revolutionary new take on an idea that has existed on paper since the 1940s, recently-hired Texas Instruments engineer Jack Kilby demonstrates the first fully-functional integrated circuit, with all of the electronic components encased in germanium. While the U.S. Air Force immediately places an order for TI’s new integrated circuits, other engineers continue to refine Kilby’s invention, with Fairchild Semiconductor producing ICs encased in silicon. The move to silicon for ICs leads to smaller electronic devices and the development of microcomputer technology.
