Hazardous Substance Management

VisEra established the QC 080000 hazardous substance management system to manage hazardous substances. We adopted the principle of minimizing the use of hazardous substances that are harmful to human health or pollute the environment. All products produced for customers meet international regulations and customers’ requirements for the use of hazardous substances in products. VisEra also continues to promote replacement plans for hazardous substances in the production process. We require suppliers of process materials to provide statements to guarantee that their products do not contain substances harmful to the environment that are banned by international organizations and ensure that products meet the requirements of the customers as well as regulations such as the EU RoHS Directive. Materials must be 100% compliant with regulations and customer requirements for zero hazardous substances and may not use perfluorooctanoic acid (PFOA) and its related substance and N-methylpyrrolidone (NMP). We completed the evaluation and introduction of PFOA and NMP alternative materials in 2020, and no PFOA and NMP were used in 2021. We continued to evaluate/execute the PFHxA replacement program starting from 2022 and we plan to complete the introduction of 100%PFHxA replacement materials (42 photoresists) by the end of 2024.

PFHxA alternative material introduction schedule: The use and management of chemicals is closely related to environmental protection and sustainable development, and has been one of the focuses of various sustainability indicators in the international community. VisEra is committed to green and sustainable management, and we constantly optimize our production processes to reduce the chemical consumption per unit. During this period, we have completed 35 chemical reduction projects (average reduction of ~40%).
