Integrated Circuits
	Integrated circuits (ICs) are the power source of the information revolution • When computers were made of discrete parts, wires of every transistor (3), capacitor (2), resistor (2), etc. had to be hand-connected • Labor intensive, expensive, error prone, unreliable, cumbersome, … even with robots! • Integrated circuits solved that by 2 ideas Integration -- circuits built as a unit from like parts Photolithography -- printing process to make chips
