ASML's Physics Moat: A Sold-Out Order Book Meets a 22-Nanometer Breakthrough
Published on 09/19/2026 at 08:41 | Editorial boerse-global.de
The most consequential company in the global chip industry does not design processors, write software, or operate fabs. It sits in Veldhoven, in the southern Netherlands, and it decides how far Moore's Law can still be pushed. ASML's grip on that question tightened on two fronts this week: a research milestone that extends extreme ultraviolet lithography deeper into the sub-nanometer era, and a capacity picture that shows its order book effectively closed through 2027.
22 Nanometers, and a Million Wafers
The research institute imec reported reaching a resolution of 22 nanometers using CAR photoresist on High-NA EUV systems — a foundational step for chipmaking beyond the 1-nanometer threshold. Intel Foundry has already moved the technology onto the production floor, processing more than one million wafers for certification, development, and manufacturing, including components for future processors.
ASML is simultaneously squeezing more output from the tools it already ships. After a demonstration in San Diego, JPMorgan noted that the company is sticking with its tin-based light source and has ruled out alternative approaches such as free-electron lasers. The demo rested on raising droplet frequency from 60 to 100 kilohertz. The payoff is concrete: by the end of the decade, the machines are targeted to turn out up to 50 percent more wafers.
Capacity Sold Out, and a 2028 Ambition
Chief Financial Officer Roger Dassen said the artificial intelligence boom has fundamentally changed how customers view their own roadmaps. Existing EUV manufacturing capacity is now almost entirely spoken for through 2027, and chipmakers have already made firm commitments for the next-generation High-NA tools.
To keep pace, ASML is weighing a meaningful expansion of output. Analysts at JPMorgan reported Monday that the company is evaluating options to build more than 110 EUV machines in 2028. Management expects to produce at least 80 units in 2027 and is targeting a 30 percent increase the following year.
Should investors sell immediately? Or is it worth buying ASML Holding?
The long-term groundwork is already visible on the ground. Construction began on September 8 at a new large campus in Eindhoven, which will be rolled out in stages with office space, a logistics center, and modern manufacturing halls, eventually accommodating as many as 20,000 employees. The first expansion phase is scheduled for completion in 2029. Alongside the build-out, ASML plans to work closely with leading chipmakers on lithography systems for larger semiconductors and modern data-center architectures.
Two Sessions, Two Readings of the Same Stock
The market's reaction to the production plans was not uniform. After the 2028 figures surfaced, the shares dipped intraday on Tuesday as investors debated feasibility and the precise shape of the ramp. Bernstein nonetheless reaffirmed its buy rating on Tuesday, according to media reports.
By Friday the tone had shifted. The stock closed at EUR 1,456.80, up 2.3 percent on the day, bringing its year-to-date advance to 58 percent. An earlier Friday reading had put the shares at EUR 1,439.00, a gain of 0.9 percent, with the year-to-date increase at 56 percent.
Morgan Stanley sees room for more. Demand from memory and logic foundry customers suggests ASML could exceed the upper end of its own quarterly guidance. The force behind that view is the relentless investment pressure on chipmakers: with contract prices for DRAM and NAND on the rise, producers must upgrade capacity quickly or risk falling behind in the displacement battle of the next process generations.
A Moat Built From Physics, Not Patents
None of this unfolds in a vacuum. Geopolitical restrictions on the China business remain a persistent theme, and Beijing's research institutes have reported early attempts to pattern nanosheet transistor structures using deep ultraviolet (DUV) tools instead of EUV. Those efforts, however, are a long way from economical mass production.
As long as ASML's High-NA systems remain the only key to commercially viable yields in the sub-nanometer range, pricing power stays in Veldhoven. The barrier to entry is not a patent portfolio — it is an industrial ecosystem without parallel anywhere in the world.
