Brief description of the process
Semiconductor integrated circuit refers to the use of oxidation, etching, diffusion and other methods to form a large number of electronic circuits to form various diodes, transistors and other electronic components on a small area, in order to complete a specific logic function (such as and, or, NAND, etc.), and then achieve the preset circuit function. The production process of semiconductors requires high requirements, covering various complex processes such as lithography, precision cutting and grinding. A large amount of wastewater will be produced in the process of semiconductor production, There are many kinds of pollutants in semiconductor wastewater with complex components, which usually include various heavy metal wastewater, organic wastewater and silicon and Fluorine Wastewater; meanwhile, the process cooling water of semiconductor PCW system must be filtered for reuse (see water treatment application).
