Case Study CH-1135 Essential Expertise for Water, Energy and Air Background Semiconductor fabs use large volumes of water in the manufactur- ing process. This water is used to convey process chemistry and to wash and rinse the wafers at many stages during fabrication. Semi- conductor fabs also have large chiller systems that are used to supply chilled water to the produc- tion area’s PCW (Process Cooling Water). Regulating the fab’s m
