Clean Technology Implementation for Climate Resilience
As the regulations and requirements for environmental sustainability become more and more significant, and the investment in transformational products that meet market needs gradually brings benefits, PTI has taken a proactive approach to mitigation and adaptation, including the development of clean technology as its primary axis of action. To create a win-win situation for both the economy and the environment, PTI has developed a blueprint for sustainable corporate management.
Strategy 1
Annually identify climate-related risks and opportunities based on the TCFD framework.
Strategy 2
Adopted a clean technology development strategy.
Strategy 3
Invested in the development of clean technologies, such as Fan-Out Panel Level Packaging (FOPLP) and advanced packaging.

Fan-Out Panel-Level Packaging (FOPLP) Advanced Technology
Facing the impacts of climate change, PTI recognizes the importance of improving energy and resource efficiency. The semiconductor packaging and testing industry is moving toward greater diversification and advanced technologies, with trends including smaller product sizes, enhanced functionality, lower power consumption, and more environmentally friendly materials. PTI continues to strengthen its R&D capabilities and invest in advanced packaging technologies to meet growing customer demand. In response to industry trends and increasing demand for advanced packaging and testing capacity, PTI has invested in new equipment to expand production capacity and support the development of next-generation products.
PTI has invested in FOPLP technology, which enables thinner packages, increased wiring density, and improved electrical performance. Compared with transistor scaling processes, large-size panel-level packaging provides advantages in mass production efficiency and production capacity. To reduce manual handling, PTI has introduced an Automated Material Handling System (AMHS) in its FOPLP production lines. The system improves per capita output efficiency and enables higher productivity within the same cleanroom space, supporting smart and clean technology design.

Renewable Energy Roadmap and Actions Toward a Net Zero Future
The plans for using renewable energy are mainly implemented in the three following stages based on the development of the renewable energy industry:Stage 1
In compliance with the requirements of the Renewable Energy Development Act for major electricity users, the usage of renewable energy amounted to 8,535,594 kWh/year in 2023, achieving 10% of the electricity contract capacity of the installation of renewable energy facilities.
Stage 2
Gradually increasing the share of renewable energy through methods such as solar and wind power, with a target of reaching 5% by 2025 and 15% by 2030.
Stage 3
Achieve the government’s net zero emissions targets and meet RE100 supply chain requirements set by customers by 2050.
Renewable Energy Deployment
In 2025, PTI generated 3,481,396.600 kWh (12,533.028 GJ) of renewable energy, all of which was self-generated and self-consumed. In addition, 35,345,529 kWh (127,243.904 GJ) of externally procured renewable energy was supplied through renewable energy transfer. The Company’s total renewable energy (solar energy) consumption reached 38,826,925.600 kWh (139,776.932 GJ) for the year, reducing carbon emissions associated with electricity consumption.
During the year, PTI increased renewable energy procurement and transfer by 15 million kWh, bringing annual renewable energy consumption to 37.5 million kWh and achieving its target of a 5% renewable energy usage ratio.
