Path To Net-Zero Emissions In IC Packaging

To strengthen climate resilience and accelerate towards net-zero emissions, ASE has implemented comprehensive carbon reduction strategies and management frameworks to practice responsible actions and achieve performance results. In our efforts to reduce our carbon footprint, we strive to design production facilities and processes that prioritize eco-efficient production and the creation of environmentally friendly products. Furthermore, we implement sustainable energy solutions and advocate for a low-carbon supply chain to further enhance our decarbonization efforts.

Sustainable manufacturing: A commitment to carbon reduction

At the forefront of our sustainability journey is the establishment of a comprehensive carbon inventory, which serves as the foundation for measuring our performance in carbon reduction. In alignment with the ISO 14064:2018 standard, we meticulously quantify greenhouse gas emissions across various categories using specific emission factors. This rigorous assessment process allows us to identify emission hotspots and uncover opportunities for significant reduction.

Taking our Kaohsiung facility (ASEKH) as a prime example, we have identified that in 2023, a staggering 42% of our emissions stem from Scope 2 electricity usage, while 56% arise from Scope 3 value chain emissions. Our analysis reveals that the primary areas contributing to carbon emissions are electricity consumption, capital goods, and purchased goods and services.

In response, we have developed a robust carbon reduction action plan for ASEKH, focusing on designing eco-efficient production facilities. Our strategy emphasizes the integration of renewable energy and water management in our manufacturing processes. Additionally, we are committed to collaborating with our suppliers to accelerate the shift towards low-carbon materials and energy-efficient equipment.

Sustainable factory

ASE has collaborated with academic experts to utilize AI technology for the 3D design and modeling of semiconductor plants. Our cutting-edge AI-3D technology allows for automated and efficient optimization of 3D design and modeling for high-tech plant facilities. Through the implementation of digital twin applications and all-digital management, we are paving the way for smart factory design, energy-saving practices, water management, and waste recycling networks.

In addition, we have incorporated cutting-edge AI and advanced Industry 4.0 technologies to boost factory production efficiency, implement smart energy management, and enhance water operations. Our bumping factory in Kaohsiung has been recognized by the World Economic Forum Global Lighthouse Network for effectively implementing Fourth Industrial Revolution technologies, which has led to a significant boost in production and shorter order lead times.

Sustainable energy usage

Since the main source of GHG emissions in the semiconductor industry is electricity usage, continuous efforts have been made to improve energy efficiency. A recent area of focus has been improving the electricity efficiency of thermal processes by integrating energy utilization in facility systems and production machinery. For example, in optimizing electricity usage in heating processes, our strategies include implementing high-power centralized heating to reduce energy waste, incorporating energy recovery systems, improving heat convection mechanisms to minimize heat loss, and streamlining heating processes. In parallel, we are exploring the use of new materials like non-thermal curing materials and low melting-point materials to further decrease energy consumption in heating processes.

While significant progress has been made in improving energy conservation across our manufacturing processes, we are committed to further reduce greenhouse gas emissions by progressively increasing the use of renewable energy. ASE has signed a 20-year memorandum of understanding with power suppliers to start providing green energy starting from 2026, supporting the company’s efforts to reach its net-zero emission target.

Sustainable procurement

At ASE, we have integrated energy-saving design configurations into our equipment procurement process, ensuring that new machines are designed with power-saving capabilities in mind.

Furthermore, to reduce carbon emissions from materials, we take into account the entire lifecycle — from the acquisition of raw materials and manufacturing to transportation, usage, and waste disposal. Specifically, we focus on the design of raw materials, minimizing the use of precious metals, selecting low-carbon high-polymer sources, and reducing material consumption at our suppliers’ manufacturing facilities to lower the carbon footprint of the materials we use. Lastly, ASE is actively engaging with suppliers to collaboratively develop the next generation of equipment and materials.

Collaborative pathways to carbon reduction

Many carbon reduction measures in the manufacturing process, whether through optimizing existing equipment and materials or developing new processes, require changes to the current manufacturing process. When implementing carbon reduction in the procurement process within the supply chain, challenges arise when considering the need to switch to alternative materials, such as the risks to product quality and potential increases in procurement costs. Low-carbon solutions should maintain similar process characteristics while minimizing the impact of process changes, which is crucial for accelerating the industry’s transition to low-carbon practices.

Effective collaboration across the supply chain is crucial for achieving carbon reduction goals. Open communication and cooperation among end customers, factories, and suppliers are vital. Establishing common objectives and implementing a robust communication model are key to speeding up the carbon reduction process throughout the supply chain. Together, we can build a sustainable industry chain for a greener future.
