The first mass produced integrated circuit was released on the market in 1961. It was developed in 1960 by a team under Bob Noyce, at Fairchild Semiconductor Corp, Palo Alto CA, USA.

The "Type F" was a bistable RS (Reset/Set) Flip-Flop constructed using four NPN bipolar transistors and two resistors diffused into a single monolithic chip of silicon. The maximum operating clock speed is 1 megahertz and the delay is 50 nanoseconds.
