Integrated circuit
From the Simple English Wikipedia, the free encyclopedia that anyone can change
An integrated circuit (more often called a microchip, silicon chip, computer chip, or chip) is a piece of specially prepared silicon (or another semiconductor) into which a very complex electronic circuit is etched using a photographic technique. Silicon chips can contain computer processors, memory and special devices. The chip, which is very fragile, is normally surrounded by a tough plastic package, and electrical contacts are provided through metal legs sticking out of the package.
