In the creation of semiconductor wafers, ultrapure water is vital in every critical fabrication step.
Stringent purity requirements mean that lapses in quality can cause expensive delays
In semiconductor manufacturing, ultrapure water (UPW) is essential to every stage of production. From wafer cleaning to final rinses, even the smallest impurities can lead to costly defects and equipment failure. A single 8-inch wafer requires up to 2,000 gallons of UPW to achieve necessary cleanliness levels.
In an industry where atomic-level contaminants can destroy millions in product, high-purity water is the invisible foundation upon which the digital economy rests.
The Hidden Costs of Subpar Water Quality
With the cost of extreme ultraviolet (EUV) lithography machines at about $350 million, the cost of complete semiconductor fabrication plants reaching $15-20 billion, and maintenance alone costing up to $500 million annually, manufacturers keep to 24/7 production schedules to amortize the investment, so even small breaks in production can result in large losses.
- Yield loss: Even trace contaminants — invisible particles, dissolved metals at parts-per-billion levels, or organic compounds — can transform profitable production runs into catastrophic losses. Modern chip facilities use up to
10 million GPD of ultrapure water, making contamination stakes enormous.When yield drops from 95% to 90% due to water quality issues, the difference isn’t just a 5% loss in revenue. It’s often the difference between profitability and loss for entire production cycles. A single contaminated batch represents hundreds of thousands in wasted processing time, energy, and skilled labor.
- Fouling and equipment damage: Substandard water creates equipment degradation that compounds over time. Impurities accumulate in process tanks and etching tools, creating scaling, corrosion, and fouling that make precision instruments unreliable. This increases maintenance frequency and reduces equipment lifespan.
- Unexpected downtime: When water fails specifications in high-volume facilities, many interdependent systems stop and production lines halt, causing losses in production, customer delivery delays, and contractual penalties.
The Ripple Effects: Reputational and Supply Chain Risks
For Tier 1 semiconductor suppliers, reliability defines brand identity. Poor water systems create cascading risks throughout global supply chains. In today’s interconnected economy, where AI development, electric vehicles, and consumer electronics depend on steady semiconductor supplies, even minor production interruptions can trigger worldwide shortages.
What Causes Water Quality Breakdowns in Fabs?
Legacy systems designed for earlier semiconductor generations often lack the capacity and precision required by today’s demanding production environments. Many facilities operate without adequate redundancy, creating single points of failure. The absence of real-time monitoring means water quality degradation often goes undetected until significant damage occurs.
Poor source water management compounds these challenges. As municipal water supplies face increasing stress from climate change and infrastructure aging, variability in feedwater quality creates additional burdens on treatment systems designed for more predictable conditions.
How Fluence Helps Prevent the Cost of Failure
Fluence approaches water quality challenges with integrated systems requiring comprehensive solutions. Despite variable source water conditions, our NIROBOX™, NIROFLEX, and integrated systems provide reliable treatment with reverse osmosis, ultrafiltration, and CEDI polishing.
These solutions feature built-in redundancy, ensuring single-component failures don’t compromise entire production lines. Validated, packaged approaches draw on global high-tech industrial experience, delivering proven solutions rather than experimental technologies.
Remote monitoring and control capabilities prevent quality drift before it becomes downtime, using real-time analytics to identify potential issues and automatically adjust system parameters. Scalable design ensures facilities can meet expansion requirements without complete system rebuilds.
Desalination and Water Reuse for Resilience
In 2021, drought in Taiwan disrupted the global chip supply and forced TSMC to truck in water tanks to maintain production, highlighting how water supply disruptions threaten global technology supply chains.
The trouble isn’t going away. An estimated 40% of existing semiconductor manufacturing facilities are located in watersheds projected to face severe water stress by 2030. And the trend is accelerating. More than 25% of semiconductor fabs currently under construction, and 40% of those announced since 2021, are in similarly high-risk areas. Fortunately, there are ways to prepare.
Wastewater reuse systems can recover and repurify process water, dramatically reducing consumption of fresh water while maintaining essential quality standards. Combining desalination, ultrapure water production, and water reuse creates a comprehensive water management ecosystem that insulates facilities from external supply disruptions.
