Semiconductors contribute to an extensive range of electronic appliances, due to their use in chips within computers, solar cells and mobile phones. Up to 75 Litres of water is required to produce one chip, starting from removing impurities in the silicon wafer and leading onto its cleaning and oxidisation process, producing a protective film to reduce chemical impurities and current leakage.
The water required for the production of semi conductors is ultra pure, a standard of water quality that high exceeds the everyday parameters. To purify the water to this level, particulates and organics needs to be removed from the water before the reverse osmosis stage – This will further the filtration by removing ~99% of bacteria, ions and dissolved solids from the water. A polishing stage is next achieved by using deionisation resin, removing all ions and salts before finally directed through an Ultraviolet sterilisation system to kill any remaining bacteria and inhibit its future growth.
