EUV Lithography: Companies, Startups & Research

ASML Inc, TSMC, Intel Corporation, Samsung and IMEC are prominent EUV participants in the supplied facts. Their work spans High-NA projection, resist and process materials, mask engineering and patterning integration. Other active organizations include Zeiss SMT, Lam Research, Applied Materials, Tokyo Electron, Synopsys and Shin - Etsu Chemical.

ASML Inc and ASML Netherlands B.V. are central to scanner development, while Zeiss SMT supplies projection optics for EUV scanners. Tokyo Electron, Applied Materials and Lam Research work on resist processes, etch and pattern transfer. The system depends on coordinated equipment, optics, masks and materials rather than a single supplier.

IMEC, the Chinese Academy of Sciences and the University of Chinese Academy of Sciences are notable research organizations in the facts. IMEC has 114 publications in its recent activity breakdown, while the Chinese Academy of Sciences has 69. Recent work also involves National Yang Ming Chiao Tung University, which collaborated with TSMC on EUV mask imaging.

The facts record $911.4 million in grants across 31 awards since 2020 and $245.0 billion across 26 funding rounds. These figures include grants and investments associated with semiconductor companies and infrastructure, not only dedicated EUV research. Treat the round total as ecosystem-level activity rather than a measure of EUV-specific R&D funding.

Taiwan Semiconductor Manufacturing Company leads the listed holders with 113 patents, followed by Shin - Etsu Chemical Co. with 112 and Zeiss SMT with 101. ASML Netherlands B.V. has 71 listed patents. The holder data also includes Tokyo Electron, Applied Materials, Lam Research and TRUMPF Laser Systems for Semiconductor Manufacturing.

Patent activity declined 54.5% in the latest 12-month period compared with the previous 12 months. The facts list 850 patents across the 24-month window. This decrease contrasts with continued work on High-NA projection, masks, resists and process integration, so it describes the patent trend rather than a halt in technical development.

EUV is an established advanced patterning technology, while High-NA is moving through qualification and early production. ASML and Intel reported more than one million wafers processed on High-NA scanners across certification, research and production. That milestone indicates substantial tool use, but it does not mean all activity represents high-volume manufacturing.

October 2026 research reported on-wafer conversion of multinuclear tin photoresists to improve hydrolytic stability, alongside a study of limits in an EUV-absorbing photoacid generator. In August 2026, TSMC and National Yang Ming Chiao Tung University reported high-contrast imaging using topological quasi phase-only masks. ASML and ZEISS examined Hyper-NA systems in October 2026.

The United States leads the listed country activity with 7,691 documents, followed by Japan with 3,045 and Germany with 2,758. Taiwan has 2,423, South Korea 2,298 and the Netherlands 2,255. These country totals overlap across international activity and should not be added as exclusive shares.

Advanced logic is the largest listed application, with 1,632 documents, followed by AI and HPC chips with 1,260 and DRAM manufacturing with 694. The facts also identify mobile and consumer chips and quantum devices. Recent activity increased for DRAM manufacturing and AI/HPC chips, while advanced logic activity declined in the comparison window.
