SEMI Expands Semiconductor Back-End Facility Database with AI and Compound Semiconductor Focus — SEMI (Semiconductor Equipment and Materials International)

Event summary

2026 edition of the Worldwide Assembly & Test Facility Database now tracks 820 facilities, up from 750 in 2025.
New data fields highlight AI/HPC, photonics, and compound semiconductor capabilities across global back-end infrastructure.
Over 360 facilities support compound semiconductors, while 170 focus on AI/HPC and 70 on photonics applications.
Expanded coverage includes new facility classifications for substrate platforms and advanced packaging technologies.

The big picture

The expansion of SEMI’s database reflects the growing complexity of semiconductor back-end manufacturing, driven by AI infrastructure and emerging materials like SiC and GaN. As facilities increasingly specialize in niche technologies, supply-chain visibility becomes critical for investors and manufacturers navigating regional concentration risks.

What we're watching

Regional Expansion: The pace at which China and Taiwan are adding semiconductor back-end facilities will shape global supply-chain dynamics.
Technology Alignment: How quickly OSATs adapt to AI/HPC and photonics demand will determine their competitive positioning.
Market Consolidation: Whether the top 10 OSAT capital expenditure leaders can maintain dominance amid rising specialization in compound semiconductors.
