[Reporter Hong Youfang/Hsinchu Report] TSMC, the leading wafer foundry, continues to invest in expanding production. In response to water shortages that may affect production shutdowns, the Tainan Science Park plant is actively investing in recycled water resources. This year, the world’s first semiconductor industry recycled water plant has been launched. The cost of water per kilowatt-hour As high as 60 yuan, the company estimates that in the second quarter of next year, it is expected to supply 20% of the water consumption of its own Nanke plant, and in the future it will increase the water supply to 20 TSMC Nanke plants.

TSMC entered Nanke in 1997, when it was still a sugarcane field. Over the past 25 years, it has successively invested in the 8-inch wafer factory 6, the 12-inch wafer 14 factory super factory, advanced packaging and testing factories, wafer Yuan 18 super factory area, each larger and more modern than the other, together with the P8 and P9 plants of Wafer 18 under construction, TSMC has a total of 20 factories in Nanke, covering an area of ​​about 186 hectares, of which The eighteen factory covers an area of ​​100 hectares, with as many as nine factories, which can be called the largest fab.

In the future, water can be supplied to 20 plants

Liu Deyin, chairman of TSMC, said that the company is committed to co-prosperity with the environment through green manufacturing. The Nanke factory area is built in accordance with the indicators of Taiwan's green building and the US green building LEED certification system, and imports water resources from TSMC Nanke's industrial recycled water plant. The sustainable goal of using 100% renewable energy and net zero emissions by 2050.

Due to the strong demand for water in advanced manufacturing processes, TSMC spent two and a half years building a nine-kilometer-long ring pipe project in the Nanke Park in order not to compete with the people for water, and to prevent production shutdowns caused by possible water shortages in the south. The world's first recycled water plant for the semiconductor industry has been put into use this year. The recycled water plant can currently supply 10,000 tons of recycled water per day, and it is expected to increase to three in the next year.

The reclaimed water volume is 50,000 tons per day, which is estimated to supply about 20% of the water consumption of the Nanke plant in the second quarter, which is equivalent to 1,600 water trucks. The replacement rate of reclaimed water will reach 60% by 2030.
