Dr. Arthur Chuang

Vice President, Operations/Facility

Striving to become the benchmark of eco-friendly companies in the semiconductor industry, TSMC is dedicated to developing a sustainable operational environment, pursuing the best pollution prevention technologies, and developing a renewable circular economy.
Dr. T.S. Chang

TSMC Fellow and Vice President, Operations/Advanced Technology and Mask Engineering

TSMC cares about environmental protection. We've introduced energy-eﬃcient designs to advanced processes and optimized raw material usage through innovative ideas like source management and reduction, which will be applied to future facilities as well to expand our carbon reduction and waste reduction eﬀorts as part of our contribution to a sustainable society.

Climate and Energy

In the face of a changing global climate, TSMC has not only strengthened its resilience to climate change, but also made preparations to lessen the possible impact disasters could have on operations and made efforts to reduce greenhouse gas emissions. As declared in the Corporate Social Responsibility Policy and Environmental Protection Policy, responding to climate change is the responsibility of a sustainable business. TSMC faces the harsh challenges of climate change in collaboration with business partners, academia, government, and all of society by continuing to use energy more efficiently and by using renewable energy. TSMC strives to become a world leader in green production.

Water Stewardship

Semiconductor processes have become complex as they advance from 2D structures to a 3D FinFET architecture, which in turn increases the types and quantity of the chemical materials used. Water is vital to cleaning wafers and maintaining a clean environment. TSMC has established various water recycling applications through water resource risk management, expansion of diverse water sources, and the development of pollution prevention techniques in order to maximize the efficiency water use throughout the water cycle in its facilities. In 2019, the Company took further steps to regulate the water management framework of its facilities to ensure the reasonable allocation of facility water resources in response to seasonal temperature changes.

Circular Resources

TSMC's waste management strategies are primarily focused on source reduction. TSMC continuously minimizes resource consumption at the source, adjusts raw material usage parameters and technical solutions for process improvements, and collaborates with suppliers to achieve material optimization and minimization. After raw materials are used in production processes, on-site recycling is prioritized so that resources are sufficiently reused to delay the disposal of materials as waste.

Air Pollution Control

TSMC is committed to reducing air pollution. In addition to compliance with the "Air Pollution Control and Emissions Standards for the Semiconductor Industry" and "Stationary Pollution Source Air Pollutant Emissions Standards" in Taiwan, TSMC's air pollution prevention practices include the adoption of best available technology, such as source categorization and multi- station treatment, as well as continuous collaboration with industry experts to improve the eﬀectiveness of terminal prevention facilities so that concentrations of pollutants emitted to the atmosphere can be equal to or less than governmental standards.
