HISTORY

In 1823, Baron Jons Jacob Berzelius discovered silicon (Si), which today is the basic component of processors. In the year of 1903, Nikola Tesla patented the first electrical logic circuit called "gates". 1947-1948 were important years for computer chip improvement; John Bardeen, Walter Brattain, and William Shockley invented the first transistor. The first technology for a computer chip was invented by Jack Kilby in 1958, but it wasn't a computer chip, per say; it was just the technology that made the computer chip possible. The first commercial microprocessor computer chip was made in 1971 by Federico Faggin (shown at left) at Intel, on November 15. That is the history of the computer chip.
