Jack Kilby Texas Instruments Robert Noyce Fairchild Semiconductor hybrid integrated circuit integrated circuit
The first working integrated circuits were invented by Jack Kilby at Texas Instruments and Robert Noyce at Fairchild Semiconductor. Kilby recorded his initial ideas concerning the integrated circuit in July 1958, successfully demonstrating the first working integrated example on 12 September 1958. Kilby's invention was a hybrid integrated circuit (hybrid IC). It had external wire connections, which made it difficult to mass-produce.
