At the Taisil branch, most facility and crystal-growing equipment has been in operation for nearly 30 years since the plant was established in 1995. Although well maintained, prolonged use has inevitably led to declining efficiency, creating a noticeable gap compared with new-generation high-efficiency equipment. To ensure energy efficiency in operations and advance green manufacturing, the company launched a large-scale energy-saving equipment upgrade project.

This project covers several key equipment upgrades:

1. Air Compression System – Three aging 200-horsepower fixed-speed screw compressors were replaced with a single 580-horsepower variable-speed screw compressor. The new system automatically adjusts operating speed based on demand, reducing unnecessary energy consumption.
2. Chilled Water System – Outdated fixed-speed chillers were replaced with ceramic oil-free variable-speed centrifugal chillers. This single upgrade alone delivers annual savings of over 3 million kWh of electricity and more than 1,500 tons of CO₂e reduction, yielding highly significant results.
3. Boiler System – A 580kW variable-speed two-stage screw compressor heat pump replaced the traditional natural gas boiler, cutting fuel consumption, improving energy conversion efficiency, and reducing carbon emissions.
4. Crystal-Growth Power Supply – SCR-controlled power modules were upgraded to IGBT-controlled modules, offering faster response and more precise control. This not only improves energy efficiency but also enhances the stability and yield of the crystal growth process.

Through this project, the Taisil branch is achieving the following annual outcomes:

1. Electricity Savings – 4,707,799 kWh saved annually, equivalent to the annual electricity use of about 1,130 households.
2. Carbon Reduction – 2,826 metric tons of CO₂e emissions reduced annually, equivalent to the carbon absorption capacity of 7.3 Daan Forest Parks (a 26-hectare urban park in Taipei, Taiwan) in one year.

This initiative not only reduces energy consumption and carbon emissions in operations but also demonstrates the company’s commitment to embedding ESG principles into green manufacturing. By upgrading equipment and optimizing energy efficiency, GlobalWafers further strengthens its sustainable competitiveness, establishes a best-practice model for cross-site knowledge sharing, and advances the semiconductor industry toward a low-carbon future.

To improve material utilization, reduce industrial waste, and advance environmental sustainability, GlobalWafers has promoted fine-wire slicing technology. However, in wafer processing, wire breaks in slicing machines often cause roller groove deformation, leading to ingot scrap and raw material waste. Traditional mechanical sensors lacked sufficient sensitivity to detect wire breaks immediately and halt operations, and current sensor would also be affected by cutting water, resulting in persistent material losses.

GlobalWafers’ newly adopted smart wire-break detection system incorporates an acoustic emission sensor in addition to existing mechanisms. By monitoring acoustic signals in real time, the system can rapidly identify wire break events and instantly trigger machine responses, significantly shortening reaction times. This innovation effectively resolves the limitations of traditional sensors, reducing ingot losses and equipment damage while advancing the Company’s waste- and carbon-reduction goals.

The project has delivered three major benefits:

• Reduced Scrap: Yield recovery rate from 20% to 80% following a wire breakage, significantly lowering wafer scrap and material waste.
• Zero Waste: The multi-wire slicing station, which previously produced an average of 13.3 tons of cutting oil waste each month, has now achieved zero output after adopting the fine-wire slicing process.
• Carbon Reduction: Annual CO₂ emissions have been reduced by 19.6 tons.

This system not only enhances process stability and reliability but also effectively minimizes resource waste and contributes clear environmental benefits, underscoring the GlobalWafers dual-track commitment to smart manufacturing and sustainable development.

In line with sustainable development strategies, the project team adopted a dual approach combining source reduction and end-of-pipe collection to promote waste reduction and resource circulation. Gallium dust generated during production is first captured through dust collection systems, preventing it from entering downstream cleaning processes. Wastewater samples are then analyzed to determine concentration distributions. High-concentration gallium wastewater is diverted and collected separately for performance testing and treatment by qualified recycling partners, while low-concentration wastewater is managed by the plant’s treatment facilities to reduce system load and ensure stable compliance. Through processes such as chemical coagulation and electrolysis, the external partner not only treats the wastewater effectively but also recovers gallium metal of economic value.

This model has significantly enhanced the plant’s processing efficiency while ensuring effective cost control. The project’s demonstrates positive benefits. It is expected to deliver stable cost savings of approximately NT$250,000 per month, equivalent to about NT$3 million annually. This not only shows a substantial improvement in operational efficiency but also provides tangible economic returns.

By implementing this project, GlobalWafers has moved beyond the traditional model of relying solely on centralized treatment. Supported by data-driven verification, active collaboration with capable partners, and the establishment of a diversion management system, the initiative not only reduces treatment burdens but also ensures effluent quality consistently meets the park’s regulatory standards to reduce environmental impact , while creating added value through resource recovery. This practice highlights the company’s ability to balance environmental compliance, resource circularity, and economic performance, and it provides a replicable model for other plants to further reinforce the sustainability and resilience of overall operations.

GlobalWafers is one of the world’s top three semiconductor wafer manufacturers, with operations spanning Asia, Europe, and the Americas. As a key player of the high-tech industry supply chain, the company actively adopts renewable energy and low-carbon solutions to meet the high ESG expectations of customers worldwide. GlobalWafers officially joined the RE100 initiative in 2022 and announced in 2025 that it would accelerate renewable energy usage  by advancing the goal of 100% across its global sites from 2050 to 2040. At the same time, it pledges to achieve net-zero emissions by 2050 following the Science Based Targets initiative (SBTi). This long-term green power procurement demonstrates GlobalWafers’ role as a trusted supply chain partner and reflects the company’s proactive efforts in promoting environmental sustainability.

In the past, when certain equipment was shut down, acids with remaining usable value inside the machines were often discharged directly to the wastewater treatment facility. The resulting waste liquids and sludge were classified as industrial waste, leading to additional treatment costs and environmental burdens. To address this issue, the company redesigned the recovery pipelines, channeling the spent acid into recovery buffer tank. Once the equipment restarts, the stored liquid is fully reintroduced into the production process. A quality monitoring system ensures that the recycled acid consistently complies with process standards, allowing for safe, stable, and efficient reuse.

Since its implementation, the project has already delivered significant results. Estimates show a reduction of approximately 934 kilograms of waste sludge each month, equivalent to an annual decrease of 11,208 kilograms. This achievement not only alleviates the pressure on waste treatment systems but also generates three key benefits:

• Environmental: Lower discharge of waste liquids and sludge, reducing the load on treatment facilities and mitigating environmental impact.
• Operational: Reduced consumption of fresh acid and lower disposal expenses, creating cost savings.
• Sustainability: Reinforces the company’s commitment to green manufacturing and environmental responsibility.

This recycling mechanism represents more than the optimization of a single process and has the potential to be extended across similar equipment within the group. Looking ahead, GlobalWafers plans to broaden the application of this technology and further explore waste liquid regeneration methods and acid life-cycle monitoring. These efforts will allow for more precise tracking of acid usage, longer service life, higher recovery rates, and ultimately the circular economy goal of minimizing waste generation and maximizing resource circulation.

Through this recycling mechanism, GlobalWafers once again demonstrates its strong commitment to environmental stewardship and contributes to the green transformation of the semiconductor industry. The company will continue refining its processes, improving efficiency, and building a high-performance, low-carbon, and sustainable manufacturing model, working alongside global customers and partners to create a more competitive and sustainable future.

In energy saving and resource management, the Zhunan plant carried out 17 energy-saving projects in 2024, achieving annual electricity savings of 2.24 million kilowatt hours, equivalent to about 5% of total electricity use, and reducing carbon dioxide emissions by 1,106 metric tons. This reduction is comparable to the annual carbon absorption of 2.9 Daan Forest Parks. Through initiatives such as replacing chiller units, optimizing hot-zone structures, applying variable frequency control, and advancing computer virtualization, the electricity intensity per unit product decreased by 15%. One project alone, replacing a high-efficiency chiller unit, saved 1.99 million kilowatt hours annually and reduced nearly 1,000 metric tons of carbon emissions. In daily operations, the company also actively promotes green office practices, including paperless workflows, LED lighting, double-sided printing, energy-efficient air conditioning, carpooling, and video conferencing.

In water resource management, the factory introduced reverse osmosis recycling systems, condensate recovery, and reuse of slurry from chemical mechanical polishing processes. These measures raised the overall water recycling rate to 77%, saving 55,588 m3 of water annually. This is equivalent to the yearly water consumption of about 760 four-person households. Resource circularity has also delivered results. By remelting silicon ingot head and tail scraps, reusing defective products, and collaborating with the Industrial Technology Research Institute (ITRI) to develop high-value recycling technologies for silicon carbide and diamond powder, the waste output intensity per unit product decreased by 35% compared to the previous year. The reuse rate reached 85%, reflecting tangible progress in advancing the circular economy.

In addition to process optimization, GlobalWafers has also contributed to pollution prevention and community engagement. At the Zhunan plant, the average suspended solids in effluent were only 15 mg/L, significantly lower than the park standard of 300 mg/L. The concentration of particulate matter in emissions was just 3 mg/Nm³, well below the standard of 100 mg/Nm³. The company continues to add acid gas pretreatment systems and upgrade sludge filter presses to further minimize environmental impact. Since 2019, GlobalWafers has adopted the coastline of Zhunan Township in Miaoli for five consecutive years, organizing beach cleanups with over 800 participants. The company has also supported the Wennei community in Zhunan in establishing an ecological monitoring and environmental education platform to protect the environment and promote biodiversity.

Through comprehensive actions in energy efficiency, water recycling, resource circularity, pollution prevention, and community engagement, GlobalWafers continues to deepen the results of green manufacturing. The company is moving forward toward higher efficiency, lower carbon emissions, and sustainable development.

One of the challenges in the crystal growth process lies in determining the optimal timing for material replenishment. If replenishment occurs too early or too late, it can result in energy waste. In the past, due to reliance on subjective experience, it was difficult to consistently monitor the actual progress of silicon melting and consumption, requiring prolonged periods of high-power heating and thus reducing energy efficiency. As process requirements continue to rise, GlobalWafers has been actively introducing AI technology, shifting from the traditional model of relying on human judgment to a technology-driven approach based on “objective image data” to achieve smart manufacturing.

The AI image recognition system deployed by GlobalWafers can learn complex and nonlinear characteristics such as melt surface patterns, contrasts, and hierarchical changes, thereby enhancing its ability to identify different melt conditions. By incorporating differential techniques and adaptive filter designs, the system effectively strengthens noise resistance, enabling it to perform reliably even under limited image quality or fluctuating lighting conditions.

The AI system can detect grayscale variations at different melt stages in real time and automatically issue feeding signals at the appropriate moments. Compared with traditional manual judgment, the system can complete analyses within seconds. Through rapid automated detection and feedback, it significantly improves both the accuracy and efficiency of feeding decisions while avoiding additional compensatory heating.

The benefits of this technology are clear, delivering both process optimization and energy-saving  outcomes while embodying the value of digital and sustainability-driven “dual transformation”:

• Improved Efficiency: Overall melting time is reduced by approximately 11-17%, helping to enhance production line utilization and operational performance.
• Reduced Energy Consumption: Each crystal puller can save an average of about 14% in electricity consumption, effectively reducing energy loss and carbon emissions caused by additional heating.
• Optimized Human Operation: The system alleviates the stress and burden on operators who previously had to monitor the melt surface for extended periods, reducing the risk of human error while improving comfort and consistency.

The adoption of this technology underscores GlobalWafers’ ongoing investment in smart manufacturing and energy management. It also reflects the company’s commitment to implementing energy conservation and carbon reduction through a scientific and data-driven approach. As a successful case combining digitalization and decarbonization, it aligns with the industry’s active pursuit of “dual transformation.” Looking ahead, the company will continue to advance its smart manufacturing blueprint, drive process upgrades and operational optimization, and steadily move toward the goals of high performance, low carbon, and sustainable development.

GlobalWafers Co., Ltd. (GlobalWafers), upholding the principle of “Responsible Growth,” has officially committed to science-based carbon reduction targets under the Science Based Targets initiative (SBTi), pledging to achieve net-zero greenhouse gas emissions across its entire value chain by 2050.

The Science Based Targets initiative is an internationally recognized benchmark for low-carbon transition. It helps companies and organizations set emission reduction targets aligned with the latest climate science, ensuring consistency with the Paris Agreement’s decarbonization requirements to limit global warming to 1.5°C above pre-industrial levels, or well below 2°C.

Following the signing of the SBTi commitment, GlobalWafers will submit its target plan in accordance with SBTi’s Absolute-based Approach. To actively implement its net-zero roadmap, GlobalWafers not only follows the Science Based Targets initiative with an ambitious decarbonization pathway covering direct, indirect, and value chain emissions, but also officially announced in June 2025 the acceleration of its renewable energy transition. The company advanced its RE100 target for achieving 100% renewable energy across all subsidiaries from the original 2050 deadline to 2040, with net-zero emissions to be achieved by 2050.
