Semiconductor fabrication plant requires input Industrial process water2 evidenceEstablished relation
Semiconductor fabrication plant depends on Industrial process water.
Mechanism
Wafer processing rinses with ultrapure water between steps; a fab uses millions of gallons a day. Recycling reduces intake but not the need.

Semiconductor fabrication plant requires input Lithography tools2 evidenceEstablished relation
Semiconductor fabrication plant depends on Lithography tools.
Mechanism
Patterning at leading-edge nodes uses extreme ultraviolet scanners from a single supplier; fab capacity is bounded by tool deliveries.
