A serious accusation from the United States government is shaking up the global semiconductor industry, targeting Dutch powerhouse ASML. US Commerce Secretary Howard Lutnick has reportedly raised concerns with ASML executives, suggesting that one of their highly advanced extreme ultraviolet (EUV) lithography machines may have found its way to China. This would represent a significant breach of the stringent export controls that have blocked the sale of EUV systems to China since the Trump administration.
These EUV systems are not just any equipment; they are the only tools on Earth capable of printing the most intricate patterns for advanced semiconductors. While senior US officials claim to have evidence of ASML shipping EUV-related components to China, they have yet to publicly disclose this proof, even to ASML itself. ASML firmly denies that any such EUV machine has ever been present in China, standing by its rigorous internal tracking systems.
Why ASML’s Technology is a Global Linchpin
Even if you’re outside the chip industry, understanding ASML’s role is crucial. This Dutch company, though largely unknown to the public, is arguably the most vital player in the global AI boom, alongside giants like Nvidia and the hyperscalers. ASML holds a singular monopoly on the machines that perform EUV lithography, a process essential for creating the microscopic circuits on today’s most powerful chips.
Every cutting-edge processor produced by TSMC, the foundry behind chips for companies like Nvidia and Apple, relies heavily on ASML’s tools. These sophisticated machines represent decades of research, development, and billions in investment by ASML. This unparalleled dominance has propelled ASML to become Europe’s most valuable public company, with a market capitalization recently soaring to around $700 billion, fueled by insatiable AI-driven demand.
This immense scale underscores why the China allegation is so critically important. Should even a single EUV machine have circumvented controls and landed in Chinese hands, it would constitute one of the most impactful breaches of the US-led export control regime. This regime was specifically designed to prevent advanced AI capabilities from bolstering Beijing’s military and industrial sectors.
ASML’s Defense: Unwavering Tracking and Strategic Sales
ASML’s CEO, Christophe Fouquet, has previously addressed the strictness of their operations. He asserts that ASML meticulously tracks every single machine it has ever shipped, ensuring they are either actively used by monitored customers or have been dismantled and returned to the company. Fouquet emphasized that the complexity of EUV technology makes it virtually impossible to reverse-engineer without prior access to the full system, something he insists China has never had.
The company also maintains an internal “firewall,” intentionally segregating employees with access to sensitive EUV technology, documentation, and training from those who don’t. Notably, ASML’s China-based staff are deliberately kept on the side of this firewall that restricts EUV access. This layered approach aims to protect their intellectual property and comply with international regulations.
Beyond security, there’s a compelling commercial logic that pushes back against the idea of ASML risking an illegal EUV sale. ASML does sell older-generation deep ultraviolet (DUV) tools to China, equipment it first shipped over a decade ago. Fouquet described these sales as a protective measure, designed to maintain a generational gap while allowing for continued business without inadvertently creating a future competitor.
With an anticipated 20% of its 2026 revenue projected to come from these legally permitted DUV sales to China, ASML has a significant financial incentive to adhere strictly to export controls. Jeopardizing its standing as Europe’s most valuable industrial monopoly and potentially losing billions in legitimate revenue over a single, illicit EUV transaction simply doesn’t align with their business strategy.
Unpacking the Allegations and Broader Implications
Despite ASML’s strong denials and robust internal controls, the US government’s allegations remain unproven in the public eye. Until the Commerce Department releases its evidence, it’s prudent to reserve judgment on the veracity of the claims. This ongoing tension highlights the delicate balance between national security and global commerce in the high-stakes world of semiconductor manufacturing.
Adding another layer of complexity, the Commerce Department, under Secretary Lutnick, recently committed up to $150 million in taxpayer money to xLight, a startup developing next-generation light-source technology. While xLight’s CEO views his company as a future partner to ASML, creating hardware to integrate with existing machines, ASML’s Fouquet remains unconvinced, stating his company doesn’t need xLight’s technology to maintain its lead.
The timing of the US government’s scrutiny of ASML, while simultaneously funding a potential challenger, raises questions that warrant examination, though no public connection has been drawn between the two. Furthermore, other ventures like Substrate, backed by Peter Thiel, are explicitly pursuing rival EUV technology, aiming to directly compete with ASML. This competitive landscape could also play into the broader geopolitical chess game.
The pressure on ASML extends beyond EUV systems. A bipartisan bill currently moving through Congress proposes a far more extensive measure: an effective ban on all ASML deep ultraviolet (DUV) shipments to China. These DUV tools represent approximately a fifth of ASML’s expected 2026 revenue, demonstrating the immense economic impact such a ban would have. The potential ripple effects of these decisions will undoubtedly shape the future of global technology supply chains.
