* [http://www.intel4004.com/images/iedm_covart.jpg Cover of the IEDM program] The Silicon Gate Technology, created in 1968 by Federico Faggin at Fairchild Semiconductor, was first presented by Faggin at the IEEE International Electron Device Meeting on October 23, 1968 in Washington D.C. It was the only commercial process technology for the fabrication of MOS integrated circuits with self-aligned gate that was later universally adopted by the semiconductor industry. The SGT was the first technology to produce commercial RAMs, CCD sensors, non volatile memories and the microprocessor providing for the first time all the fundamental elements of a general purpose computer with LSI integrated circuits.
* [http://www.intel4004.com/images/elect_cov_pg1.jpg Electronics September 29, 1969] The cover of Electronics features the Fairchild 3708, the world's first commercial integrated circuit using Silicon Gate Technology, designed by Federico Faggin at Fairchild in 1968.
* [http://www.computerhistory.org/collections/accession/X1320.97 Busicom Calculator Engineering Prototype] (Gift of Federico Faggin to the Computer History Museum, Mountain View, California). The CHM collection catalog shows pictures of the engineering prototype of the Busicom 141-PF desktop calculator. The engineering prototype used the world’s first microprocessor to have ever been produced. This one-of-a-kind prototype was a personal present by Busicom’s president Mr. Yoshio Kojima to Federico Faggin for his successful leadership of the design and development of the 4004 and three other memory and I/O chips (the MCS-4 chipset). After keeping it at home for 25 years, Faggin donated it to the CHM in 1996.
