Before Federico Faggin joined Intel in 1970, the development of the 4004 was rather slow. Federico developed several design innovations at Intel that made it possible to fit the microprocessor in one chip, including new methodology for random logic chip design using silicon gate technology<ref>Faggin. Il padre del chip intelligente, Angelo Gallippi, 2002, 88-7118-149-2</ref>. Faggin developed the 4004 testing tool, chip and logic design concurrently with the layout of all the chips of the entire MCS-4 system.

At the time, Intel was only known for their memory chips. On 15 November 1971, they publicly announced the first commercial microprocessor in the 15th issue of [[Wikipedia:Electronic News|Electronic News]]. The prophetic ad read: ''"Announcing a new era in integrated electronics"''. The chip was designed by Federico Faggin, Ted Hoff and Masatoshi Shima; it received U.S. Patent [http://www.google.com/patents/US3821715 #3,821,715].
