How silicon is made - material, making, history, used ...

The basic process heats silica and coke in a submerged electric arc furnace to high temperatures. High temperatures are required to produce a reaction where the oxygen is removed, leaving behind silicon. This is known as a reduction process. In this process, metal carbides usually form first at the lower temperatures. As silicon is formed, it displaces the carbon. Refining processes are used ...

Magnesium and sand are heated together and silicon is produced by an exothermic reaction. The product is placed in acid to remove magnesium oxide and unreacted magnesium. Small amounts of silanes are produced by the reaction of magnesium silicide (a side product) with the acid. These react spontaneously with air to give spectacular but harmless small explosions.

Silicon Wafer Production and Specifications

Silicon Wafer Specifi cations Diameter The diameter of the silicon wafers are specifi ed either in inches or mm. Although an inch is 25.4 mm, the diameters of wafers in inches are usually multiples of 25.0 mm (e.g. 4 inches = 100 mm), which should be clarifi ed beforehand with the supplier. The tolerance of the diameter is typically +/- 0.5 mm.
