An integrated circuit or monolithic integrated circuit is a set of electronic circuits on one small flat piece of semiconductor material, usually silicon. Large numbers of tiny MOSFETs integrate into a small chip.

Who developed integrated circuits?

Solution by Robert Noyce

Robert Noyce invented the first monolithic integrated circuit chip at Fairchild Semiconductor in 1959.

Who manufactured the first integrated circuit or chip?

This is Jack Kilby's first integrated circuit. He invented it at Texas Instruments in 1958. From TI: "Comprised of only a transistor and other components on a slice of germanium, Kilby's invention, 7/16-by-1/16-inches in size, revolutionized the electronics industry.
