An integrated circuit, or IC, is a semiconductor-based electronic device, sometimes as small as a human fingernail, that contains many switching elements, or transistors. Integrated circuits are often referred to simply as chips. The first integrated circuits were invented separately around 1958 by Jack Kilby at Texas Instruments, and by Robert Noyce at Fairchild Semiconductor. The invention of the IC paved the way for the seminal introduction, in the early 1970's, of the first "single-chip" microprocessors such as the Intel 8080 processor first sold in 1974.
