ULTRAPURE RELIABILITY for Advanced Semiconductor Manufacturing

Ultra pure water (UPW) is used in fabrication plants for removing inorganic salts and organic matters from the wafer surface, the presence of which directly affects the number of chips or devices that can be produced. With 1,500 litres of UPW typically used to wash one silicon wafer, it's safe to say that UPW is the invisible foundation of semiconductor manufacturing.

For over forty years, Veolia has engineered, built and operated UPW systems for the world’s most advanced fabs, combining global expertise with precision manufacturing and digital control. Our solutions deliver absolute consistency and uptime, enabling faster production ramps, higher yields and lower total cost of ownership.

Veolia partners with the world’s leading semiconductor manufacturers to deliver ultrapure water systems engineered for today’s most advanced nodes - and tomorrow’s.

Our expertise spans the full UPW lifecycle: from system design and fabrication to commissioning, operation and continuous optimisation. Whether you’re building a new fab or upgrading an existing facility, we deliver repeatable purity, digital control and long-term reliability across every drop.
