TSMC Regenerates Electronic-Grade Carbon Dioxide to Aid Green Transformation

Supply chain carbon management is integral to TSMC's net-zero emissions transition. Following collaboration with an ammonia supplier to introduce blue ammonia produced using Carbon Capture and Storage (CCS) technology, TSMC has partnered with a hydrogen peroxide supplier on carbon capture. This new initiative focuses on capturing and purifying tail gas emissions from the hydrogen peroxide production process, transforming them into electronic-grade carbon dioxide that meets semiconductor manufacturing quality standards, raising the value of resource circularity. In May 2026, the regenerated electronic-grade carbon dioxide from this collaboration was adopted at Fab 14B with an estimated annual carbon reduction of approximately 1,200 metric tons, strengthening the resilience of TSMC’s green supply chain. Recycling Tail Gas, Transforming into High-purity Electronic-grade MaterialsBoth hydrogen peroxide and electronic-grade carbon dioxide are crucial chemicals in semiconductor manufacturing. The upstream hydrogen production process, necessary for producing hydrogen peroxide, emits tail gas containing carbon dioxide. To enhance supply chain sustainability and put circular economy principles into practice, TSMC and its supplier jointly set plans to install a dedicated recovery pipeline system at the hydrogen plant. This system captures tail gas emitted after combustion or reaction, channels it into raw material storage tanks for centralized collection, and then uses adsorption-desorption towers to remove residual hydrogen. Next, a purification tower separates impurities and enhances purity, resulting in electronic-grade carbon dioxide.To ensure that regenerated electronic-grade carbon dioxide meets the stringent high-purity standards required for semiconductor manufacturing, TSMC not only guided the supplier in establishing a comprehensive Certificate of Analysis (CoA) mechanism during the production phase to ensure each batch meets specifications, but also provided specialized technical support. This included assisting the supplier with tail gas composition analysis and purity testing, and guiding adjustments to operational parameters during the purification process to enhance separation efficiency and gas purity. TSMC also helped the supplier to optimize factory production line operations and tank truck purge standards to mitigate impurity risks, and conducted on-site audits to review production management processes, comprehensively improving the supplier's technical capabilities and quality control standards.

To further cultivate talent and spark innovation, TSMC developed the "Trade Secret Registration Innovation Index Analytics System" in 2023. This system was the first to use an AI model to identify inventors with innovative potential who had not yet received awards, and paired them with award-winning colleagues for one-on-one mentoring. By 2025, this initiative had nurtured 120 inventors with innovation-potential, 22 of whom successfully received the Golden Trade Secret Award.Building on accumulated innovative achievements and talent cultivation experience, TSMC has once again made another breakthrough in 2026 by developing the "Trade Secret Creativity Integration Partner (CIP) Intelligent System," based on Generative AI technology. This system incorporates an in-house Large Language Model (LLM) and integrates Retrieval Augmented Generation (RAG) tools. It also utilizes Golden Trade Secret Award registration data for supervised learning training, ensuring the model possesses the ability to identify and create technological innovations that meet TSMC's high standards. It can precisely extract key technical features from different registration cases and analyze variations in their innovation levels. Through human-AI collaboration, the system effectively evaluates and ranks registration cases, generates specific explanations and forward-looking recommendations, and even offers perspectives previously unconsidered by the registrants. This inspires deeper, more comprehensive thinking while providing the evaluation committee with a recommended list of Golden Trade Secret Award candidates. The result is a significant enhancement in TSMC's competitive advantage in trade secret management and innovation.

TSMC is committed to improving sustainability risk management. The Company is gradually replacing lead-acid batteries with lithium iron batteries in uninterruptible power supply (UPS) systems for new and existing fabs to save energy and achieve other environmental benefits. For this project, TSMC partnered with suppliers and internal and external experts to launch the "Lithium Iron Battery Generation Upgrade Project." This initiative aims to further strengthen operational environmental safety and battery energy management. The project involves inventorying and optimizing approximately 408,000 lithium iron batteries across domestic and international fabs, and validating battery safety performance as well as the effectiveness of Battery Management System (BMS) protection through Thermal Runaway experiments. By Q1 2026, first and second-generation lithium iron battery management systems were successfully upgraded entirely to the third generation. This new system can precisely detect voltage, state of charge, current, temperature, and state of health, and instantly transmit this data back to the fab's Supervisory Control and Data Acquisition (SCADA) system, improving energy storage safety and management efficiency.Advancing Intelligent Safety Management with Three Generations of EvolutionLithium iron batteries, with their high energy saving, long cycle life, and environmentally friendly characteristics, have become crucial components for stable UPS operation and optimized energy efficiency. After completing in-fab production line verification in 2017, TSMC began using first-generation lithium iron batteries. These were monitored for voltage via sampling boards to ensure system operational safety. In response to the International Electrotechnical Commission's IEC 62619 Safety Requirements for Secondary Lithium Cells and Batteries industrial applications, TSMC adopted second-generation lithium iron batteries in 2018. The BMS (Battery Management System) in these batteries added monitoring functions for state of charge, temperature, and state of health in addition to voltage, improving the monitoring of battery status.To deepen its continuous investment in battery technology and comply with the NFPA 855 Standard for the Installation of Stationary Energy Storage Systems published by the National Fire Protection Association (NFPA), TSMC began research into third-generation lithium iron battery applications with suppliers in 2019. The third-generation BMS is able to monitor critical parameters such as voltage, state of charge, current, temperature, and state of health. It also integrates with the factory's SCADA system, enabling real-time data transmission and remote diagnosis. If abnormality occurred, it can identify fault point immediately, which improves the efficiency of handling emergency responses by 25%. Furthermore, in 2024, thermal runaway experiments were conducted on the lithium iron batteries to verify their safety performance under extreme conditions, laying a reliable foundation for upgrading existing systems.
