The first step, therefore, is silicon mining and purification. Among many other things, this requires energy. Energy is one of the inputs of the mining and purifying process. The output is purified silicon, which gets shipped to a computer chip factory. The computer chip factory then takes the purified silicon and makes it into a crystal wafer ...
The major environmental impacts associated with silicon derive from its mining. Carbon monoxide is a byproduct of the basic process whereby silicon is prepared from silicon dioxide, but this is a negligible source of atmospheric carbon, compared to the amount generated by combustion of fossil fuels.

Wafer — also called a slice or a substrate, is a thin slice of a crystalline silicon. The wafer serves as the substrate for microelectronic devices built in and over the wafer and undergoes many microfabrication process steps such as dopingor ion implantation, etching, deposition of various materials, and photolithographic patterning.
Aug 31, 2017· Crystalline silicon is mainly used as a semiconductor, which is a high-demand usage. Hence, a very cheap and fast method of producing silicon is used by semiconductor producers. This method is known as the Czochralski process. In this process, a thin rod tipped with a seed crystal is dipped in pure, molten silicon.

Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
The process was first developed by Siemens in the 60's and is often referred to as the Siemens process. The resulting rods of semiconductor grade silicon are broken up to form the feedstock for the crystallisation process. The production of semiconductor grade silicon requires a lot of energy.
