ASML at the Center of a Global Chip Storm

A potential breach of export controls could be a major blow to ASML's dominance in the global AI chip market.

According to Bloomberg, U.S. Commerce Secretary Howard Lutnick has expressed concerns that one of ASML's extreme ultraviolet lithography machines may have been shipped to China. This would be a significant breach of export controls, which have barred ASML from selling these machines to China since the Trump administration.

Lutnick has reportedly told senior ASML executives that he is concerned about the possible breach, and there is evidence that ASML shipped EUV-related components and transport equipment to China. However, the Commerce Department has not yet made its evidence public, and ASML denies that any machine exists in China.

ASML is a Dutch company that is crucial to the global AI buildout, as it is the only supplier of extreme ultraviolet lithography machines. These machines are used to print the most advanced semiconductor patterns, and are essential for the production of cutting-edge processors.

Every cutting-edge processor made by TSMC, the foundry behind Nvidia's and Apple's chips, depends on ASML tools. The company has a monopoly on this technology, which has made it Europe's most valuable public company.

But if even one EUV machine made it into Chinese hands, it would be a major breach of the export-control regime. This could have significant implications for the global AI buildout, and could potentially give China access to advanced chip technology.

The Commercial Logic of ASML's EUV Monopoly

ASML CEO Christophe Fouquet has argued that the company's EUV monopoly is secure, and that it is not at risk of being breached. He has pointed out that the company tracks every machine it has ever shipped, and that its employees who have access to EUV technology are walled off from those who don't.

Fouquet has also argued that the only reason ASML was able to build an EUV machine in the first place was that 80% of it already existed from decades of prior knowledge. He has suggested that it is not possible to reverse-engineer a machine you've never had, and that nobody in China has had one.

The xLight Challenge to ASML's Monopoly

There is also a challenge to ASML's EUV monopoly from a startup called xLight. The company is developing a next-generation light-source technology that is seen as a potential rival to ASML's EUV machines.

xLight's CEO has said that the company sees itself as a future partner to ASML, rather than a rival. However, ASML's CEO has been polite but unconvinced by this framing, and has made clear that the company does not see itself as needing xLight's technology to keep its lead.

The Politics of ASML's EUV Monopoly

There are also political implications to ASML's EUV monopoly. The Commerce Department, under Lutnick's leadership, has invested $150 million in xLight, a startup that is developing a rival technology to ASML's EUV machines.

This investment has been seen as a way for the government to support a startup that is challenging ASML's monopoly. However, it could also be seen as a way for the government to exert influence over ASML, and to push the company to make concessions to its rivals.

The Future of Lithography

There are also other challenges to ASML's EUV monopoly on the horizon. Peter Thiel, a well-known technology investor, has backed a startup called Substrate, which is developing a rival EUV technology.

This technology is seen as a potential rival to ASML's EUV machines, and could potentially give ASML's competitors a way to challenge its dominance in the global AI chip market.
