ASML ships its first High-NA EUV production tool as maskless lithography gains ground in specialty fabs

ASML's four-decade climb to lithography dominance reached a new milestone in 2025-2026 with the first high-volume shipments of its Twinscan EXE:5200B High-NA EUV scanner^[1]. The EXE:5200B carries a price tag of roughly $380 million per unit and is now being installed at Intel and Samsung for sub-2 nm production^[1], while a parallel wave of maskless multi-beam electron-beam tools is quietly expanding into advanced packaging and rapid-prototyping workflows.

From Philips joint venture to EUV monopoly

ASML was founded in 1984 as a joint venture between Philips and ASM International, entering a market then dominated by Nikon and Canon^[1]. Its strategy - co-developing technology with chipmakers rather than dictating standards - proved decisive. The pivot to immersion lithography, which ASML and TSMC developed jointly, was the first inflection point: immersion ArF systems reduced the exposure wavelength to 193 nm and kept Moore's Law viable down to the 7 nm node. Competitors judged the investment too high; ASML made the bet and widened the gap.

EUV followed the same pattern. EUV lithography uses 13.5 nm wavelength light, roughly 14 times shorter than 193 nm DUV, enabling single-exposure patterning where immersion required double or triple passes. The project consumed more than $9 billion in R&D over three decades and required ASML to orchestrate a global supply chain - including Carl Zeiss for ultra-flat mirrors - that no rival has been able to replicate.

High-NA raises the stakes again

The EXE:5200B pushes the numerical aperture from 0.33 to 0.55, achieving roughly 8 nm single-exposure resolution versus 13.5 nm on standard EUV. ASML CEO Christophe Fouquet confirmed the first EXE:5200B shipment in mid-2025, citing a claimed 60% productivity gain over the R&D-grade EXE:5000. Key adoption milestones so far:

• Intel accepted the first production EXE:5200B at its D1X fab in late 2025, targeting its 14A node with risk production starting in 2027.
• SK hynix installed a production-grade EXE:5200B at its DRAM fab in September 2025, the first memory maker to do so.
• Samsung received its first EXE:5200B in late 2025 and a second unit in the first half of 2026, aimed at its 2 nm foundry lines.
• TSMC is testing R&D versions but has not yet committed to commercial-scale deployment.

ASML is currently building roughly 12-15 High-NA systems per year and has guided toward approximately 20 per year by 2028.

Maskless tools find their lane

While High-NA EUV dominates headlines, a separate technology is gaining traction in lower-volume applications. Multi-beam electron-beam lithography (MEBL) systems write patterns directly on wafers without a photomask, eliminating mask fabrication time and cost. The global multi-beam e-beam lithography market was valued at $692 million in 2025 and is forecast to reach $1 billion by 2031, growing at a 7.5% CAGR. IMS Nanofabrication led the segment with over 30% market share in 2025.

Throughput remains the binding constraint - e-beam tools cannot match EUV's wafer-per-hour rates for high-volume logic. But for advanced packaging, silicon photonics, secure chip ID, and rapid design iteration, maskless systems offer a faster path from tape-out to silicon. Multibeam Corp. secured its first Taiwan order in 2026, with National Tsing Hua University selecting its MBX multi-column platform for delivery in 2027 - a foothold in the world's densest semiconductor ecosystem.

The design implication is real: as EUV mask sets for leading-edge nodes exceed 100 layers and curvilinear mask costs climb, teams working on low-volume or frequently revised designs have a growing economic incentive to route those layers through maskless tools rather than wait for mask fabrication.

The near-term signal to watch is Intel's 14A yield data, expected as risk production ramps in 2027. If High-NA EUV delivers the promised density gains at acceptable yield, TSMC will face pressure to accelerate its own EXE:5200B deployment - and ASML's production ramp will need to keep pace with demand from all three leading-edge customers simultaneously.
