SEMICON Japan 2025 Day One : Industry Conversations, Technology Focus, and What Visitors Are Looking For

SEMICON Japan 2025 officially opened today in Tokyo, bringing together semiconductor manufacturers, materials suppliers, equipment vendors, and research organizations from across Asia and beyond. As one of the most influential semiconductor exhibitions in the region, the first day traditionally sets the tone for the entire event — highlighting current industry priorities, emerging technical challenges, and the direction of collaboration within the global supply chain.

For many visitors, Day One is less about finalized decisions and more about information exchange, technical alignment, and relationship building. Booths across the exhibition halls are hosting in-depth discussions on materials performance, process compatibility, and supply reliability — topics that continue to shape wafer-level manufacturing strategies.

Key Themes Emerging on the First Day of SEMICON Japan

Based on early-day conversations and visitor interests, several recurring themes are clearly visible across the show floor:

1. Process Stability and Yield-Oriented Materials

Rather than focusing solely on advanced-node hype, many engineers are asking practical questions related to process repeatability, tool qualification, and yield optimization. This is especially evident in discussions around test wafers, monitor wafers, and other non-device substrates used during process development and equipment calibration.

Test wafers are increasingly viewed as process control tools, not just consumables. Visitors are paying closer attention to parameters such as flatness consistency, surface quality, thickness uniformity, and lot-to-lot stability.

2. Regional Supply Chain Coordination in Asia

Another noticeable trend on Day One is the emphasis on regional collaboration within Asia, particularly among companies operating in China, Japan, and Southeast Asia. With fabs distributed across multiple countries, procurement teams are seeking suppliers who understand regional process standards, logistics requirements, and communication efficiency.

Rather than pursuing a single global solution, many visitors are evaluating flexible supply models that can support different fabs, R&D lines, and pilot production environments.

3. Practical Solutions for Mature and Specialty Processes

While advanced nodes remain important, a significant portion of discussions today center on mature nodes, specialty processes, power devices, sensors, MEMS, and compound semiconductor integration. These applications rely heavily on stable baseline processes, where supporting wafers play a crucial role in maintaining process accuracy.

This trend reinforces the importance of reliable test and monitor wafers across a wide range of diameters and specifications.

 FSM’s Participation: Technical Exchange at the Booth

As an exhibitor at SEMICON Japan 2025, FSM is participating in these conversations by engaging with visitors interested in silicon test wafers and related wafer solutions used in daily fab operations. On the first day, discussions at the FSM booth have focused primarily on:

• How test wafers are used during equipment setup, process tuning, and tool matching
• The role of dummy wafer and monitor wafers in reducing risk during process trials
• Specification considerations such as wafer orientation, thickness tolerance, and surface finish
• Supporting different fab environments across Asia with consistent quality standards

FSM’s approach at the exhibition is centered on listening and technical alignment, rather than promotion. Many visitors bring specific process challenges or qualification requirements, making these conversations highly application-driven.

Why Day One Matters for Both Visitors and Exhibitors

The opening day of SEMICON Japan plays a unique role in shaping the rest of the exhibition:

• Engineers gather early insightsbefore deeper technical meetings later in the week
• Procurement teams map potential suppliersfor follow-up discussions
• Suppliers gain clarity on what fabs are prioritizing in the coming year

For wafer suppliers like FSM, Day One provides valuable feedback on how test wafer requirements are evolving across different regions and applications.

Looking Ahead to the Rest of SEMICON Japan 2025

With several days still ahead, SEMICON Japan 2025 is expected to continue exploring topics such as equipment efficiency, materials reliability, and cross-border collaboration within the semiconductor ecosystem. As discussions move from general exploration to more focused technical exchanges, the role of supporting materials — including test wafers — will remain a consistent point of interest.

FSM looks forward to continuing these conversations throughout the exhibition, exchanging insights with industry professionals, and gaining a deeper understanding of how fabs across Asia are adapting their process strategies in an evolving market.
