The physical process is basically melting it and then solidifying it and the last parts of the mass to solidify contain most of the impurities.
The chemical process is when you convert it to a silicon compound then you distil it then convert it back to pure silicon.
The zinc process includes reacting silicon tetrachloride with high-purity zinc vapours at 950 °C, producing silicon ( I've added the formula)SiCl4 + 2 Zn → Si + 2 ZnCl2 However, this technique was plagued with practical problems and was eventually abandoned in favour of the Siemens process.
In the Siemens process, high-purity silicon rods are exposed to Trichlorosilane at 1150 °C. The Trichlorosilane gas decomposes and deposits additional silicon onto the rods, enlarging them:
2 HSiCl3 → Si + 2 HCl + SiCl4
Silicon produced from this and similar processes are called polycrystalline silicon. Polycrystalline silicon typically has impurity levels of less than 10−9
Finally the Schumacher process which is basically the same as theSiemens process but with lower deposition temperatures, lower capital costs to build facilities and operate, no hazardous polymers nor explosive material, and no waste amorphous silicon dust waste.
Silicon is used in the manufacture of computer chips.

Silicon.
The two main elements used to make computer chips are germanium and silicon.
Silicon
Silicon Ingot:A large, cylindrical, single crystal made from purified silicon. The cylinder is sliced into thin wafers which are used for making computer chips. Silicon Wafer:Intel uses wafers of pure silicon cut from a silicon ingot to make microprocessors. Silicon, the primary ingredient of beach sand, is a semiconductor of electricity. Semiconductors are materials that can be altered to be either a conductor or an insulator.
The metalloids silicon and germanium, also in Group 14,are used to make computer chips.
silicon
Computer chips are made from silicon because it's a natural semiconductor and is the second most abundant element on Earth. To make the wafers, silicon is purified, melted and cooled to form an ingot, then it is sliced into discs.
Most likely, you mean silicon. It is certainly used in computer chips, glass, and abrasives.

espicially silicon, becos it is a very good semiconductor
