    The Integrated Circuit (IC)An IC consists of interconnected electronic components in a single piece

    (chip) of semiconductor material.

    The first planar IC

    (actual size: 0.06 in. diameter)

    In 1959, Robert Noyce (FairchildSemiconductor) demonstrated an IC madein silicon using SiO2 as the insulator and Alfor the metallic interconnects.

    In 1958, Jack S. Kilby (TexasInstruments) showed that it was possible tofabricate a simple IC in germanium.

    From a Few, to Billions The degree of integration has increased at an exponential pace over

    the past 40 years. IC performs very complex tasks.

    The number of devices on a chip doublesevery ~18 months, for the same price.

    Moores Law still holds today.
