The Integrated Circut
What is an Integrated Circut?
- Transistors, resistors, capacitors, diodes
- Transistors are like a power switch
- Resistors limit electrical flow
- Capacitors collect energy
- Diodes stop electricity
Where can you find them?
- Nearly every modern electronic device.
- Computers, phones, cars, IPods and more

What did it replace?
- The transistor replaced the vacuum tube
- Vacuum tube was bulky, hot, could burn out and slow.
size is one reason
why early
computers took
up a entire room.
- "If the auto industry advanced as rapidly as the semiconductor industry, a Rolls Royce would get a half a million miles per gallon, and it would be cheaper to throw it away than to park it."
What will replace them?
"Tyranny of Numbers"
- A Integrated Circuts became more advanced they became near imposible to build.
- Faulty connections became an issue.
- Size of circuts
- Robert Noyce perfected Kilby's idea.
How are they made?
- Jack Kilby solved these problems.
- Photolithography
- Stepping
- "Clean Room"
