TSMC Breaks Ground on Arizona Industrial Reclaimed Water Plant

Phoenix: Taiwan Semiconductor Manufacturing Co. (TSMC) announced that construction has commenced on its industrial reclaimed water factory in Arizona, with operations expected to begin in 2028. The facility is set to initially achieve an 85 percent water recycling rate, with plans to increase this to 90 percent or higher, aiming for near net-zero wastewater emissions.

According to Focus Taiwan, the facility is located on 15 acres and underscores TSMC's commitment to sustainable operations by converting industrial wastewater into ultrapure water, essential for semiconductor manufacturing. Ultrapure water is crucial for cleaning micro particles that could damage semiconductor chips, particularly advanced ones like the 4-nanometer chips produced at TSMC's Arizona fab.

Rose Castanares, president of TSMC Arizona, stated that Phoenix was chosen for TSMC's U.S. operations due to comprehensive plans by state and city governments, including a long-term water supply strategy. TSMC is committed to being a responsible neighbor by managing natural resources, especially water, responsibly.

The reclaimed water factory is part of TSMC's strategy for sustainability and ensuring a stable water supply for Phoenix. TSMC has multiple operating industrial water treatment plants in Taiwan and was the first to use industrial reclaimed water in semiconductor manufacturing in 2022.

TSMC highlighted that the Arizona plant's design will consider local water quality, which has higher magnesium and calcium levels than Taiwan's water. The company is adopting a comprehensive strategy to conserve water and promote sustainable water resource management through technologies that reduce consumption, improve quality, and enhance usability.
