Expo Grand Occasion: The "Vanguard" of the Global Semiconductor Industry

From December 17 to 19, 2025, the 49th SEMICON JAPAN grandly opened at Tokyo Big Sight, attracting 1,216 exhibitors from 35 countries and over 120,000 professional visitors. Centered on "Technological Innovation + Ecosystem Synergy", this year’s expo focused on two core trends: AI and sustainability. It launched two brand-new summits – "AI × Sustainability × Semiconductor (AIS)" and "Metrology & Inspection Summit (MIS)" – comprehensively showcasing the latest technologies and development trends of the global semiconductor industry.

Technological Evolution: From 1.4nm Process to AI-Driven Manufacturing, Connectivity Technology Becomes a Key Pillar

Among the core technological breakthroughs and trends presented at the expo, three development directions are closely linked to basic components such as connectors and wiring harnesses:

1. Process Miniaturization and High-Density Integration

DNP’s global debut of the 1.4nm-class nanoimprint lithography (NIL) template and Rapidus’ progress in 2nm process have become focal points. These advanced processes place unprecedented precision and reliability requirements on the internal connection systems of equipment:

• Ultra-high-density signal transmission to ensure accurate      delivery of control signals for nanoscale processes

• Ultra-stable power connections to meet the power needs of      extremely precision equipment

• Miniaturized and lightweight design to adapt to space      constraints inside equipment

2. The Wave of AI-Driven Smart Manufacturing

The newly launched AIS Summit attracted global giants such as NVIDIA, Intel, and Micron to discuss how AI is reshaping semiconductor manufacturing. The explosive growth of AI servers and data centers poses three major challenges for connectors and wiring harnesses:

• High-speed data transmission: Supporting 100Gbps+ transmission rates to ensure real-time, lossless transmission of AI training data

• Low-latency signal interaction: Guaranteeing control system response times in the microsecond range to meet precision manufacturing needs

• Balance between heat dissipation and reliability: Solving heat dissipation issues in high-density data centers to ensure long-term stable operation

3. Green Manufacturing and Sustainable Development

"The Future of the Semiconductor Supply Chain: Challenges of Sustainable Development" served as the closing session of the expo, emphasizing the importance of equipment energy efficiency and environmental design. This requires connection systems to:

• Adopt low-power design to reduce energy consumption

• Withstand high temperatures and extreme environments to extend equipment lifespan

• Use environmentally friendly materials to minimize environmental impact

Connectors & Wiring Harnesses: The "Neural & Vascular System" of Semiconductor Equipment

Throughout the expo, industry experts have reached a consensus: the reliability and performance of semiconductor manufacturing equipment depend not only on core chips and precision machinery but also on stable and efficient connection systems.

In semiconductor equipment, connectors and wiring harnesses play a critical role as the "neural and vascular system":

Especially in advanced testing and metrology equipment, the precision of wiring harness systems directly affects the yield of nanoscale processes. On-site at the expo, many equipment manufacturers emphasized that the breakthrough performance of their latest testing equipment is largely attributed to the support of customized precision wiring harness solutions.
