Relation to Other Courses
• Prerequisite:
– EECS40: Basic properties of semiconductors;
basic understanding of transistor operation
– Familiarity with the Bohr atomic model
• Relation to other courses:
– EE130 is a prerequisite for EE231 (Solid State Devices)
– EE130 is also helpful (but not required) for IC analysis
and design courses such as EE140 and EE141, as well
as for the microfabrication technology course EE143

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.

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.
