The most commonly used element in semiconductors due to its abundance (the same element that is found in sand) and ease of processing. Chips are made by growing silicon into a giant crystal, which is sliced into thin, round wafers, polished and coated with chemicals, producing layers of patterns etched into the wafer. The wafer is then cut into small squares and packaged in plastic, connecting the parts of the chip with tiny gold wires, which is ultimately placed onto a final product, such as a remote control or an anti-lock braking systems in automobiles.

name under which different crystalline forms are grouped. Microcrystalline silicon (µc-Si) is a material, whose thickness is around one µm, used to manufacture photovoltaic modules and cells (grain size 1 µm). Monocrystalline (sc-Si) is used to manufacture ingots and wafers or cells obtained by the Czochralski pulling method or by zone fusion. A wafer is composed of a single grain. Multicrystalline (mc-Si) is obtained by directional solidification in a crucible to manufacture ingots, wafers or cells (grain size: 0.1 - 10 cm). Polycrystalline (pc-Si), with a thickness of 10 to 30 µm, is deposited on a substrate for the manufacture of ingots, wafers or cells (grain size: 1 µm - 1 mm)

A nonmetallic chemical element in the carbon family of elements. Silicon - atomic symbol "Si" - is the second most abundant element in the earth's crust, surpassed only by oxygen. Silicon does not occur uncombined in nature. Sand and almost all rocks contain silicon combined with oxygen, forming silica.

Compounds of silicon also occur in the atmosphere, natural waters, and many plants and in the bodies of some animals. Silicon is the basic material used to make computer chips, transistors, silicon diodes and other electronic circuits and switching devices because its atomic structure makes the element an ideal semiconductor.
