High-NA EUV Lithography Gains Momentum Among Leading Chipmakers
By Drooid · · How we work
Industry Adoption Accelerates
ASML’s next-generation High Numerical Aperture (High-NA) EUV lithography systems, priced at roughly $400 million each, are moving from pilot projects into high-volume manufacturing. Intel reported that more than one million wafers have been processed on High-NA tools across early-stage certification, research, development and selected volume production of its Core Ultra Series 3 “Panther Lake” processors. The company says overlay, throughput and availability meet its expectations, and that chips produced on Intel’s 18A process using High-NA meet or exceed performance of comparable layers patterned with the older NXE EUV platform.
Other leading manufacturers have set concrete adoption timelines. Samsung plans to introduce High-NA EUV into DRAM mass production by 2028, targeting the sub-10 nm “0a-generation” DRAM. SK Hynix announced a similar 2028 target for memory-chip production. TSMC committed to high-volume High-NA production beginning in 2030, after earlier doubts about the technology’s cost-effectiveness. Micron has placed orders for the machines but has not disclosed a production start date.
Background and Ecosystem Coordination
High-NA EUV’s larger numerical aperture enables patterning of features about 40 percent smaller, potentially reducing the number of lithography steps required for advanced nodes. The system’s exposure field is roughly half the size of current EUV tools, making large-format photomasks essential. The industry standard has long been 6-inch masks; to unlock High-NA productivity, Intel, ASML, TSMC and Samsung are jointly developing 12-inch masks and the associated inspection, metrology and handling equipment. Intel describes the effort as a three-year “large-mask initiative” aimed at establishing standards and infrastructure for future scaling.
Official Statements & Responses
Intel said its High-NA-enabled 18A process delivers performance that meets or exceeds comparable layers on the older NXE platform. ASML’s chief executive Christophe Fouquet remarked, “I don’t think we’re at the end of [the AI boom], to be honest,” underscoring the link between AI demand and lithography investment. Samsung’s Vice Chairman Young Hyun Jun stated, “Samsung is committed to maintaining leadership in advanced semiconductor manufacturing… through breakthrough technologies and strong partnerships.”
Conflicting Reports & Gaps
ASML’s internal tracking asserts zero EUV machines in China, while senior U.S. officials have suggested the possibility of smuggled components, though no public evidence has been presented. The discrepancy remains unresolved, with the U.S. government citing undisclosed intelligence and ASML relying on its monitoring systems.
What’s Next
- Samsung and SK Hynix aim to begin High-NA DRAM production in 2028.
- TSMC plans high-volume High-NA production from 2030; a joint initiative targets a 12-inch photomask pilot line by 2031 and mass production readiness by 2033.
- Intel continues volume production on its 18A process and is expanding the large-mask ecosystem.
- The MATCH Act awaits congressional action, potentially tightening export licensing for future lithography tools.
- On June 2, 2026, the Commerce Department and NIST finalized $150 million in CHIPS Act incentives for xLight, a Palo Alto firm developing a free-electron laser source for EUV lithography, indicating parallel U.S. investment in alternative light-source technologies.
