Federico Faggin

Federico Faggin

In the late 1960s, Fairchild semiconductor scientist Federico Faggin invented a new MOS (Metal On Silicon) process called silicon gate technology that would eventually become the dominating semiconductor process for advanced integrated circuits. Early in 1970, Faggin moved to Intel where, together with Ted Hoff and Stan Mazor, he would design and build the world's first microprocessor, the Intel 4004. Many people have said (and we agree) that the microprocessor will someday be recorded as the most important invention of the twentieth century. The photomicrograph illustrates the initials F.F. (Federico Faggin) discovered on the 4004, the only set of initials to adorn the surface of this famous microprocessor.
