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 Chilled Water System – Outdated fixed-speed chillers were replaced with ceramic oil-free variable-speed centrifugal chillers.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.
