Reducing Water Usage in Semiconductor Manufacturing

Water is the world’s best cleaning agent when used wisely. Like any other industry semiconductor fabs use water for cleaning as well as for various other purposes such as cooling. The semiconductor and electronics manufacturing industry is a cornerstone of modern technology, powering devices from smartphones to electric vehicles. With the global semiconductor market projected to exceed $1 trillion by 2030, the demand for chips continues to surge, driving the construction of new fabrication plants worldwide. However, this growth comes with significant environmental challenges, particularly the industry’s heavy reliance on water resources. Semiconductor manufacturing requires vast amounts of ultrapure water (UPW) for processes like wafer cleaning, rinsing, and equipment cooling, with a single 300mm wafer fab consuming up to 5 million gallons of water daily. Amid growing concerns over water scarcity and environmental sustainability, reducing water usage has become a critical priority for the industry.

Recent research and technological advancements are addressing this challenge through innovative water recycling, process optimization, and equipment design. Among these, Canon ANELVA’s newly launched Adastra series of semiconductor and electronic component manufacturing equipment stands out as a significant step toward sustainability, achieving a remarkabl...
