Green Manufacturing

Green Manufacturing

Winbond has remained committed to green manufacturing principles. Winbond has included reducing carbon emissions as an important goal, and have implemented measures to do so starting from the research and development phase. Through methods such as optimizing our production processes and adopting zero carbon emissions gases, Winbond hopes to become a model for promoting green products, relying on our core competencies to create a green impact. In 2022, Winbond invested NT$1.334 billion into implementing environmental protection measures, and have continued to invest into reducing the environmental impact caused by our business operations. Compared to 2021, Winbond has invested 253% more funding into these efforts, with this increase mainly due to the many pollution prevention/treatment facilities built for our new Kaohsiung Fab. Winbond has continued to reduce the environmental impact caused by our operations, and the economic benefits brought about by the environmental protection investments above have totaled NT$36 million.

Smart Manufacturing Prognostic and Health Management (PHM)

By using PHM for smart health monitoring of the production process, Winbond is able to discover and repair damage to the electrostatic chuck (ESC) early before serious damage occurs, effectively reducing ESC usage costs, and reducing the number of wafers that need to be discarded due to ESC damage. In 2022, our ESC usage costs were lower by 13% compared to 2021. Winbond also discarded 55% less wafers, a major improvement.
