Bring your own copy of the lecture notes. Turn off cell phones, etc. Avoid distracting conversations EE130/230M Spring 2013 Course Overview, Slide 6 The Integrated Circuit (IC) • An IC consists of interconnected electronic components in a single piece (“chip”) of semiconductor material. • In 1958, Jack S. Kilby (Texas Instruments) showed that it was possible to fabricate a simple IC in germanium. • In 1959, Robert Noyce (Fairchild Semiconductor) demonstrated an IC made in silicon using SiO2 as the insulator and Al for the metallic interconnects. The first planar IC (actual size: 0.06 in. diameter) EE130/230M Spring 2013 Course Overview, Slide 7 From a Few, to Billions of Components • By connecting a large number of components, each performing simple operations, an IC that performs complex tasks can be built. • The degree of integration has increased at an exponential pace over the past ~40 years. Moore’s Law: The # of devices on a chip doubles every ~2 yrs, for the same chip price.
