What kinds of waters are used at Intel to make computer chips?

Intel uses several types of water in the manufacturing of computer chips, primarily ultra-pure water (UPW) for cleaning and rinsing wafers. This water is treated to remove impurities, ensuring that no contaminants interfere with the delicate semiconductor processes. Additionally, deionized water may be used in various stages of production to maintain the purity required for microfabrication. The stringent quality of water is crucial for the reliability and performance of the final semiconductor products.
