    ASE Group provides eco-efficient and responsible service to customers through the integration of sustainable practices into all stages of manufacturing, including material usage, design, procurement, production and packing. These practices help reduce costs, enhance competitiveness and reduce the impacts on environment, safety and health.

    ASE Group is committed to:

    • Complying with all applicable laws and regulations.

    • Managing hazardous substances in parts and materials that are used to make products.

    • Providing product solutions that are compact, lightweight, and energy efficient.

    • Continuously enhancing resources recycling, reducing greenhouse gas emissions, waste generation, wastewater effluent, and chemical usage.

    • Reducing product packaging and wastes.

    ASE Group Green Laboratory

    Our green laboratory is dedicated to the following:

    • Evaluation and development of green materials: Evaluation of non-toxic or low toxic product raw materials, and process chemicals.

    • Development of environmental testing technology: Establishment of monitoring technology, mechanism and standard, compliant with world environmental regulations.

    • Development of Green Process: Improve utilization rate of chemicals or raw materials; evaluate recovery, reduction and reproduction technologies for waste, wastewater and chemicals.

    • Development of Environment Friendly Packaging: Develop bio-composite packaging materials.

    Sustainable Manufacturing Measures

    Since all of the manufacturing stages are closely interlinked in terms of environmental, health and safety impact, continuous efforts are required to make incremental improvements and to achieve technological innovation. ASE aims to make such improvement and innovative efforts throughout our operations in order to continuously deliver sustainable products to customers.

      Provisions Project Benefits
    Sustainable Material Usage Use boron-free developing solution in the development process of wafer bumping. Reduce post-processing wastewater and reduce boron emissions
    Fully use RoHS-compliant non-toxic materials and components for manufacturing of wireless communication modules. Reduce environmental impact of wireless communication module products in the process of design, manufacturing and application.
    Sustainable Design Add a hardware switch on IC control functional wiring of Activity Tracker Module to coordinate with software and achieve reduction of power consumption while system is in sleep mode. Low power consumption and electricity-saving
    Replace chip antenna with integrated print antenna in the wireless communication module. Simplify manufacturing process and reduce material usage.
    Sustainable Process Use low chemical oxygen demand (COD) solution in substrate direct laser drill (DLD) process to remove brown oxide pretreatment. Reduce post-processing wastewater and COD emissions
    Use low chemical oxygen demand (COD) green detergent in stripping process. Reduce post-processing wastewater and COD emissions.
    While dicing the wafer, pure water is necessary to cool the dicing blade and rinse the wafer. Generally, a dicing machine needs a certain flow of water to achieve a stable level of water resistivity internally. When a CO2 Bubbler is used, carbon dioxide can be dissolved in the coolant water and maintain a stable optimal level of resistivity at low water flow. Significantly reduce water consumption
    Sustainable Packaging Develop environment friendly IC Tray: Use biodegradable high-molecular material - polylactide acid (PLA) for manufacturing of IC Tray. Green regeneration; reduce usage of fossil raw materials
    Develop processing and reuse methods for waste molding material from molding process for manufacturing of IC Tray. Recycle and reuse waste from manufacturing process, and reduce usage of fossil raw materials

    Enhance Product Eco-Efficiency (EE)

    In 2016, ASE established the product eco-efficiency model through industry-academic collaborations. The product eco-efficiency assessment model helps improve the quality of the environment while increasing product value. Material consumptions throughout the whole product life cycle can be significantly reduced which in turn reduces the environmental impact, and helps achieve the company's environmental goals in sustainable development.

    1. BGA Eco-Efficiency Assessment Model
    According to the assessment result, for the same system boundary and scope, the single score of damage caused by BGA (gold wire) is 6.18E-04 (Pt), approximately six times of the single score of BGA (copper wire) 1.02E-04 (Pt). Overall, the damage scores of BGA using copper wire in all categories of environmental damages are significantly lower than those of BGA using gold wire. This pushes the semiconductor industry to migrate more to copper wire.

    2. Eco-Efficiency Assessment Model for Communication Modules
    The results of the environmental impact analysis (EIA) demonstrated that the main environmental impact comes from the manufacturing stage within product life cycle, and externally purchased electricity is the main source of environmental impact. The main environmental impact generators from the raw materials are components, such as integrated circuits, ceramic substrates, metal frames. Our communication module's environmental impact mainly focuses on human toxicity risk.
