Clean Technology Services: Advanced Panel Level Fan-out Packaging (FOPLP)

e

As climate change and energy efficiency become more important, PTI believes that the packaging and testing industry will become increasingly high-tech and diversified in the future, with smaller, more versatile products, lower power usage, and environmentally friendly materials. Since industry and technological advances and increasing customer demand for advanced packaging and testing capabilities, we have acquired new equipment to enhance production capacity in order to meet customer expectations for new products and to build on this foundation to pursue advanced, high-performance packag-

ing technologies in a more aggressive manner. PTI has invested in the development of Fan-OutPanel-Level Packaging (FOPLP) technology, which offers the advantages of reducing package thickness, increasing wire density, and improving electrical performance. The Fan-OutPanel-Level Packaging (FOPLP)reduces incomplete edge wear and tear and increases area utilization, resulting in significant improvements in production efficiency and cost reduc- tion. With FOPLP, the end products are highly energy-efficient.

Achievements and Targets to Increase Investment in Clean Tech

Since 2018, PTI has invested $50 billion to build the world's first mass production base for fan-outpanel-level packag- ing, a technology that can be applied to products related to 5G, AI, biotechnology, self-driving cars, smart cities and the Internet of Things, and which will significantly contribute to the development of related products. There is no doubt that fan-outpanel-level packaging will play an integral role in the semiconductor industry.

PTI has established a 300-member R&D and engineering team to develop advanced technologies for fan-out panel -level packaging. Our research and development efforts have been focused on "fine line" and "large size." For a long time, we have worked with equipment and material suppliers to overcome the challenges of the process.

PTI has now addressed the bottleneck and moved into mass production. As part of an ongoing technological refinement process, PTI has developed the investment plan to provide more versatile and energy-efficient designs in the future.

Industrial Automation Technology: Advanced Material Handling System (AMHS)

Advanced Material Handling System (AMHS) has played a significant role for fab automation. The product weight of the fan-out packaging is close to 40kg. PTI has introduced the Advanced Material Handling System (AMHS) in P11B to meet the efficiency of mass production and transportation due to rapid development of industrial automation technology. The AMHS effectively solves the manual operation problem in an automated manner, saving manpower for each machine operation and maximizing clean room use.

Achievements and Targets to Increase Investment in Clean Tech

Application in Mass Production:

power management chip for mobile phones

Proof of Concept (POC):

TV chips, mobile phone processor chips and other packaging Compared to conventional packaging, Fan-Out Panel-LevelPackaging (FOPLP) has significantly lower power consumption because the distance required for electronics to travel is greatly reduced, which has a positive effect on consumer electronics endurance, as well as reducing the number of charging cycles for electronics, making them more energy efficient.

Involvement in Production or Distribution of Industrial Automation Technologies

1. Used RDL first (chip last) rewiring to fabricate circuit sub- strate and fan-outpanel-level packaging technology, success- fully developed automotive SoC packaging with embedded passive components, and passed the complete reliability verifi- cation of the client.
2. Successful integration of chip Middle process technology in fan-outpanel-level packaging:

System-on-Chip (SoC) and High-Bandwidth Memory (HBM)

can meet the functional usage requirements of data computing and low-latency data transmission required for product application in the HPC/Al field.

SLight-emitting diodes and control chips were used in AR/VRdevices in entertainment, medical, education and other fields; Embedded Die has also been successfully developed for use in high-end mobile devices and high-speed computing processors.

1. Successfully developed Heterogeneous Integration and entered the production stage. Through 2.5D and 3D multi-dimensional space design, multiple electronic com- ponents of different properties are integrated into a single system-in-package to support 5G, AI, IoT Core chips required for new-generation technology operations such as networking and high-speed computing.

The Development of Optimization Technologies & Systems

The following technical achievements have been made:

1. FOPLP technology development and verification has realized ultra-fine line width and spacing (Line/Space/3um) redistribution process (RDL), which is applied to high-speed computing chips.
2. Stacked with bare die to realize small chip (Chiplet) technology.

Alternative Energy

Green Power Blueprint and Conducts

The problem of extreme climate and global warming has prompted countries worldwide to take proactive measures to mitigate the impacts of climate change. PTI has made a concerted effort to achieve green sustainability through a number of measures, including the implementation of energy-saving practices, improving the energy efficiency of energy-consuming equipment, replacing obsolete equip- ment, and obtaining the ISO50001 certification of its energy management system in 2021. To further reduce the impact of carbon emissions from energy consumption, we have also invested in green power generation and usage.

Green power refers to the use of renewable energy and eco-friendly methods for generating electricity. Primary sources of energy include solar power, wind power, hydropower, geothermal, and bioenergy. Green power in Taiwan is primarily derived from solar and wind power. Apart from installing power generation equipment, green power is also purchased from renewable energy suppliers or vendors and is delivered to the factories via Taiwan Power Company's power grid. As part of the purchase, T-REC certifies the amount of energy purchased from green sources and issues a green power certificate.

Sola Power Generation Equipment Installation Plan at PTI

Green Power Usage and Acquiring Green Power Certification Process

In order to evaluate and plan the installation of green energy, the green power procurement team at PTI was formed in 2021.

The following methods were adopted:

1.Make an Inventory of Energy Consumption Conditions

Estimate the mandatory installed capacity of renewable energy at PTI'plants according to contract capacities to understand the power consumption information such as customer' number, power consumption characteristics, and consumed electricity (kWh).

2.Establish a Timetable for Completing Renewable Energy Obligations and Confirm Green Power Installation Goals

Following an analysis of both the price and power generation method of different renewable energy sources, as well as a technical assessment of the plant space and feasibility, it was determined that solar

power generation equipment would be installed. The remaining quota will be filled by purchasing green power certificates from renewable energy suppliers.

In pursuit of green sustainability, PTI will continue to pay close attention to climate change and increase its use of renewable energy in an effort to achieve net zero emissions by 2050.
