China Just Started Mass-Producing the Chipmaking Machine Export Controls Were Built to Deny It. ASML Lost €8 Billion in a Day.
On Monday, July 27, 2026, The Information reported — and Bloomberg independently confirmed — that a state-backed Shanghai manufacturer has begun mass-producing immersion deep-ultraviolet lithography scanners, the exact class of chipmaking tool a decade of U.S. and Dutch export controls was built to keep out of China’s hands. The first machines are headed to SMIC, Hua Hong, and CXMT before year’s end.
ASML’s stock took its steepest one-day hit in weeks. By the time Asian markets opened the next morning, the reaction had gone global — erasing roughly $250 billion from Nvidia’s market value and dragging Samsung and SK Hynix down more than 12% each. The same export-control wall protects ASML’s lithography monopoly and Nvidia’s AI-chip leverage over China. This week, that wall showed a crack.

The manufacturer is a little-known, state-owned firm that Tom’s Hardware and IBTimes UK identify as Shanghai Aishengna Electronic Technology Group, formed by absorbing engineering teams from two homegrown lithography efforts: Shanghai Yuliangsheng Technology — a startup with reported ties to Huawei and its chip-tool investment vehicle, SiCarrier — and Shanghai Micro Electronics Equipment (SMEE), China’s longer-established but far less advanced lithography maker. SMIC has reportedly been testing a Yuliangsheng immersion DUV scanner on an evaluation line since September 2025. The new reporting says that testing has now become production: the first units are slated for delivery this year to SMIC, Hua Hong Semiconductor, and ChangXin Memory Technologies (CXMT), China’s three largest logic and memory foundries.
The tool itself is a 193-nanometer argon-fluoride immersion scanner — the same class ASML has sold for two decades, roughly the size of a large truck, weighing upward of 18 tons, and costing tens of millions of dollars per unit. Its single-exposure rating is modest: 28-nanometer-class features, a mature node, nowhere near the cutting edge. Some components, reportedly including precision optics, are still imported from Japan. Engineers believe multi-patterning — running a wafer through the same scanner several times with offset masks — could push it toward 7-nanometer or even 5-nanometer-class work, though at lower yields than ASML-built equivalents.
ASML shares fell as much as 8% intraday on July 27 — the company’s steepest slide in weeks — wiping more than €8 billion off its market value in a single session, per Bloomberg. U.S. toolmakers Applied Materials, Lam Research, and KLA fell alongside it; ASML supplier BE Semiconductor Industries dropped nearly 10%, Soitec lost 5%, and Infineon slid almost 3%. The timing compounds an already-declining trend: China accounted for 36% of ASML’s system sales in the fourth quarter of 2025, 19% in the first quarter of 2026, and just 14% of its €6.6 billion in second-quarter 2026 system sales, as the export-control regime has progressively tightened.
SMIC already makes 7-nanometer-class chips today — on ASML-built tools, using multi-patterning. What Aishengna’s machine adds is not new process capability; it is a domestic supply path for capability China already has, one that cannot be cut off by a policy decision in Washington or The Hague. That distinction is why several analysts immediately cautioned against reading this as a technological leap, even as it registered as a strategic one.
Bank of America’s Didier Scemama called the selloff an “overreaction,” estimating that even losing 20 argon-fluoride tool sales to domestic competition would cost ASML only about €1.4 billion — roughly 2.4% of projected 2027 group sales. Barclays’ Jakob Bluestone framed Chinese-built DUV as a “small negative,” more a “likely necessity” to support China’s own output growth than a wholesale replacement for ASML. ODDO BHF’s Stephane Houri put it more bluntly: “I would take this with a pinch of salt…EUV is out of reach. Never say never, especially with the Chinese, but it’s a completely different technology.” Reuters’ Breakingviews column went further in its own headline: “ASML’s China chip threat looks overdone.”
Not everyone shrugged it off. Morningstar’s Jing Jie Yu said “the market was likely spooked by the progress of China’s chipmaking equipment capabilities,” and SPI Asset Management’s Stephen Innes warned that “the same wheel is beginning to throw investors off at speed” as the broader AI-valuation cycle wobbles. SemiAnalysis, cited by CNBC, landed in between: tool performance, production scaling, fleet reliability, the surrounding parts ecosystem, and poor economics against fully depreciated ASML machines “all stack up against China DUV” — a real disadvantage, not a fatal one.
Bloomberg over #ASML (-8,5%): 'The unnamed Shanghai-based firm is seeking to make about five DUV machines this year and is targeting about 20 next year,' the Information said. Progress on production remains at an early stage, according to the report. ASML has been banned from exporting its cutting-edge tools, namely the EUV lithography machines, to China as part of US-led export controls. It's also restricted from selling its most advanced DUV machines to the country.
This is insane — ASML drops 8% after China starts mass-producing homegrown DUV chipmaking tools. China has begun manufacturing its own immersion Deep Ultraviolet (DUV) lithography machines, one of the world's most critical tools for semiconductor manufacturing. For decades, the Dutch company ASML has dominated the global market for immersion DUV lithography systems. China has now started producing its own domestically developed alternatives.
The headline pairs ASML with Nvidia for a reason. China’s existing fleet of several hundred ASML-purchased DUV immersion tools — already running multi-patterning — is what lets SMIC fabricate the 7-nanometer-class logic inside Huawei’s Ascend AI accelerators today; the American Enterprise Institute estimates that fleet is capable of printing Huawei’s targeted 1.6 million AI logic dies in 2026 alone. What changed this week is not that capability — it is that the scanner performing the work no longer has to be one ASML sold. More domestic lithography capacity means more Huawei Ascend chips, which is the accelerator China is buying in place of the Nvidia hardware it can no longer legally import.
Nvidia CEO Jensen Huang has already conceded how far that substitution has gone. At Computex Taipei in May 2025, he called U.S. export controls “a failure,” noting Nvidia’s China market share had fallen from 95% to 50% over four years and that the company had written off multiple billions of dollars in H20 inventory as a direct result. “The export control gave them the spirit, the energy, and the government support to accelerate their development,” he told reporters. A China that can build both its own lithography tools and its own AI accelerators removes American leverage on two fronts at once — which is precisely why a five-machine-a-year rollout produced an eight-figure stock reaction.
“The export control gave them the spirit, the energy, and the government support to accelerate their development. So I think, all in all, the export control is a failure.”

The Commerce Department was already tightening enforcement before this report landed. The Validated End-User exemption that let TSMC, Samsung, and SK Hynix run China fabs without annual re-licensing expired December 31, 2025; all three now renew yearly. The Bureau of Industry and Security revised its Nvidia H200 and AMD MI325X license review to case-by-case in 2026. And on June 19, Bloomberg reported that Commerce Secretary Howard Lutnick told ASML executives directly that he suspected one of the company’s EUV machines — its most tightly controlled export — may have reached China in violation of the rules. Separately, in December 2025, Commerce signed a $150 million agreement with xLight, a startup developing an alternative EUV light source, taking equity in return.
Congress moved on the DUV gap specifically. The bipartisan MATCH Act — introduced April 2, 2026 in the House by Rep. Michael Baumgartner and April 8 in the Senate by Sens. Jim Risch, Pete Ricketts, Andy Kim, and Chuck Schumer — would ban exports and servicing of DUV immersion lithography systems to five named “covered facilities”: SMIC, Huawei, Hua Hong, CXMT, and YMTC. It gives the Netherlands and Japan 150 days to match U.S. controls or face an expanded Foreign Direct Product Rule reaching any equipment built anywhere with U.S. technology inside it. The House Foreign Affairs Committee advanced it April 22 in what lawmakers called the largest export-control markup in the chamber’s history. Sen. Risch said the goal is to “prevent adversaries from undermining the US semiconductor industry”; Sen. Kim put the stakes plainly: Washington must ensure “China cannot develop the capability to produce such technologies itself.” Three months later, the reporting says, it already has — at least at the entry level.
Five machines this year, twenty next year, against ASML’s own 130 — on paper, a rounding error. But the market didn’t price the machines; it priced the premise underneath both ASML’s lithography monopoly and Nvidia’s AI-chip leverage over China: that Beijing couldn’t build the tools itself. A Shanghai firm nobody had heard of a year ago just put a visible crack in that premise, even though its machines are still, by every independent account, a full technology generation behind. Congress’s answer — the MATCH Act — was written to close this exact gap and cleared committee three months before the gap closed anyway.
