Key Trends Shaping the Market
Advanced Automotive Electronics Integration
A significant trend in Japan’s semiconductor packaging market is the integration of advanced automotive electronics. As electric vehicles (EVs), autonomous driving systems, and connected car technologies become more sophisticated, there is a growing demand for robust semiconductor packages capable of withstanding high thermal loads and complex functionalities. Japanese automotive manufacturers are increasing their adoption of Advanced Driver-Assistance Systems (ADAS), power modules, and in-vehicle infotainment, all of which require compact and highly reliable semiconductor packages. This shift necessitates packaging providers to develop heat-resistant and space-saving solutions, such as multi-chip modules and System-in-Package (SiP) configurations. Collaboration between semiconductor companies and automotive OEMs is accelerating, focusing on vertical integration and the co-development of packaging technologies tailored for vehicle environments. This convergence of the automotive and semiconductor sectors emphasizes longevity, high precision, and miniaturization as packaging priorities. For example, in December 2024, TOPPAN Corporation announced its participation in the US-JOINT consortium, a US-Japan joint initiative led by Resonac Corporation, aimed at developing next-generation semiconductor packaging technology. As a packaging substrate manufacturer, TOPPAN supports advancements in 2.5D and 3D packaging for applications like AI and autonomous driving.
Adoption of High-Density Packaging with Glass-Core Substrates
Another emerging trend is the increasing adoption of glass-core substrates for high-density semiconductor packaging, particularly for data centers, AI chips, and high-performance computing. Glass substrates offer superior dimensional stability, higher electrical insulation, and flatter surfaces compared to traditional organic materials, enabling more precise stacking and interconnection density. Japanese companies are investing in refining the manufacturing processes for glass-based substrates, enhancing yield and integration capabilities. This trend aligns with the global shift towards chiplet architectures, where multiple smaller chips are integrated onto a single substrate to function as a unified system. Japanese companies, known for their expertise in material science, are leading innovation in this area, positioning themselves uniquely to meet the performance, space, and power efficiency requirements of new computing platforms. For instance, in June 2024, Rapidus Corporation and IBM announced an expanded partnership for 2nm generation semiconductor chiplet packaging technology development. Building upon their existing 2nm node collaboration, this initiative is part of a NEDO-backed Japanese project to advance next-generation semiconductor packaging. Its goal is to establish Japan as a key player in advanced chiplet packaging by supporting AI and HPC applications and strengthening the global semiconductor supply chain.

Understanding Semiconductor Packages
Semiconductor packages are crucial structures designed to protect semiconductor devices (chips) and connect them to external circuits. Since semiconductor devices are extremely small and precise, they are vulnerable to external environments and physical impacts. Therefore, packages provide hardness, moisture resistance, and heat resistance to the device, creating the conditions for its normal function.
Semiconductor packages play a vital role primarily in electronic devices. They are used in various devices such as smartphones, computers, home appliances, and medical equipment, with specific packaging technologies adopted according to each application. These packages come in various forms, including lead frames, Ball Grid Array (BGA), and Chip-on-Board (COB), offering different options based on factors like size, thermal management, connection method, and cost efficiency.
The main functions of a package are to ensure electrical connections and to provide mechanical and environmental protection. For example, BGA packages are attached to the substrate using ball-shaped solder connections, which can maximize chip performance. The thermal management function of the package is also critical, requiring designs that effectively dissipate heat generated during device operation.
Furthermore, the manufacturing process for semiconductor packages involves various technologies. Typically, chips are first cut from wafers as individual devices and then handled to connection terminals. Subsequently, they are encapsulated with epoxy or resin and finally packaged. This process requires a cleanroom environment, with meticulous attention paid to preventing microscopic dust or contaminants from degrading device performance.
In recent years, semiconductor packaging technology has advanced, with particular attention given to 3D packaging and stacked packaging technologies. These advancements enable increased device density, leading to miniaturization and higher performance. Additionally, material selection and design are engineered to improve signal transmission speed. This forms the foundation for supporting advanced technologies such as 5G communication, AI (Artificial Intelligence), and IoT (Internet of Things).
Finally, from an environmental protection perspective, the design of semiconductor packages is also important. There is a demand for recyclable materials and environmentally friendly manufacturing processes. As more companies aim for sustainable development, future semiconductor packaging technology is expected to further evolve and meet diverse needs. Moving forward, semiconductor packages will play an increasingly important role in conjunction with technological evolution.
