What is a Silicon Wafer? Silicon is a gray, brittle, tetravalent, chemical element. It makes up 27.8% of the earth’s crust and next to oxygen, it is the most abundant element in nature. Some of the most common materials that contain silicon are quartz, agate, flint, and common beach sand, among others.

Wafer Fabrication Operator Job Description. The chips in the electronic devices we use -- ranging from smartphones to the controllers in an office building's elevators -- all start out as silicon wafers. Silicon wafers are pieces of silicon, frequently derived from sand, that go through special machinery that
This is a list of silicon producers.The industry involves several very different stages of production. Production starts at silicon metal, which is the material used to gain high purity silicon.High purity silicon in different grades of purity is used for growing silicon ingots, which are sliced to wafers in a process called wafering.

(It has recently been found that rougher cells absorb light more effectively, therefore some manufacturers have chosen not to polish the wafer.) Doping 6 The traditional way of doping (adding impurities to) silicon wafers with boron and phosphorous is to introduce a small amount of boron during the Czochralski process in step #3 above.

Design. The way a chip works is the result of how a chip’s transistors and gates are designed and the ultimate use of the chip. 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.
