TSMC fulfills its commitment to green manufacturing and environmental protection through innovation and development. TSMC pioneered introduction of artificial intelligence (AI) in its energy saving system, using neural network algorithm of machine learning (ML) to build a low energy consumption model. TSMC successfully created its industry’s first “AI Powered Chilled Water Energy Saving System” that instantly and accurately determines the optimal energy efficiency parameters, and increases average energy efficiency by 10% to 19%.

Due to the increasing complexity of advanced manufacturing process, it's a challenge to introduce green innovation, especially in the chilled water system, that may affect the operational stability of cleanrooms and yield rate. I am very glad and proud that TSMC made it.

In 2017, TSMC successfully developed the industry’s first chilled water system optimization energy-saving control program. Furthermore, the Company pioneered introduction of artificial intelligence (AI) in its energy saving system in 2019. As of January 2020, TSMC has implemented the system in twelve 12-inch fabs, saving 180 GWh electricity every year, and reducing carbon emission by 95,000 tons, equivalent to the carbon absorbed by 9.5 million trees in one year.
