Silicon chip what is it

These ingots are then sliced into silicon wafers which upon completion can now allow the doping process to begin.

Doping is a process whereby special impurities are added on to the silicon to give it the desired semi-conduction capabilities. However, before the doping procedures can begin, the wafers have to be buffered in order to get rid of any dirt that might have accumulated during the cutting process.

The surface of silicon wafers is then marked out into small identical rectangular zones that will serve as individual chips. This is followed by the creation of numerous components on the chips through the doping process which could number into thousands and even millions.

The components made can either be p-type components or n-type components. Doping can be done using different procedures.

One well known one is called sputtering. It should be mentioned, however, that this is a very delicate and sensitive process that occurs at a very minute level.

Today silicon chips are everywhere. Intel creates industry-leading and world-first silicon products. They automate factories and are embedded in automobiles and everyday devices. The most sophisticated processor can contain hundreds of millions or billions of transistors interconnected by fine wires made of copper.

Chips today may have multiple cores. Silicon, the principal ingredient in beach sand, is a natural semiconductor and the most abundant element on Earth except for oxygen.

To make wafers, silicon is purified, melted, and cooled to form an ingot, which is then sliced into discs called wafers. A chip is a complex device that forms the brains of every computing device.

While chips look flat, they are three-dimensional structures and may include as many as 30 layers of complex circuitry. Chips are fabricated in batches of wafers in clean rooms that are thousands of times cleaner than hospital operating rooms.

Fab technicians wear special suits, nicknamed bunny suits, designed to keep contaminants such as lint and hair off the wafers during chip manufacturing. Design specifications that include chip size, number of transistors, testing, and production factors are used to create schematics—symbolic representations of the transistors and interconnections that control the flow of electricity though a chip.
