Almost every high-end electronic device in use today—from the smartphone in your pocket to the servers powering the latest generative AI—owes its existence to a single, specialized company in Veldhoven, Netherlands. ASML does not make chips; it makes the machines that make the chips. Specifically, it holds a global monopoly on Extreme Ultraviolet (EUV) lithography, a process so complex it is often described as the most sophisticated piece of machinery ever created by humans.
For the global economy, ASML is a critical single point of failure. For geopolitical rivals, particularly China, it is the ultimate prize. As the AI boom accelerates, the pressure to acquire or replicate this technology has intensified, turning the Dutch firm into a focal point of the “chip war” between Washington and Beijing.
In a recent detailed discussion with TechCrunch, ASML’s CEO Christophe Fouquet addressed the persistent rumors of Chinese breakthroughs in lithography. Fouquet, who took the helm in 2024 after more than a decade with the company, dismissed the notion that China has successfully reverse-engineered EUV technology, citing a fundamental physical reality: you cannot copy what you do not possess.
The Physical Impossibility of Reverse Engineering
The core of ASML’s defense is a strict “no-entry” policy regarding its most advanced hardware. EUV machines are behemoths—roughly the size of a school bus—requiring months of assembly, hundreds of specialized suppliers, and a price tag ranging from $200 million to over $400 million per unit. Because of these dimensions and the extreme precision required for their operation, they cannot be smuggled or hidden.
“To do reverse engineering on a system, you first need to have that system,” Fouquet explained. He emphasized that ASML maintains a rigorous inventory of every EUV machine ever produced. These units are either actively monitored at customer sites or have been decommissioned and returned to the Netherlands. To date, not a single EUV machine has been delivered to China.
This lack of physical access creates a massive barrier for Chinese engineers. While Beijing has invested billions into its domestic semiconductor industry to achieve “chip independence,” the jump from Deep Ultraviolet (DUV) lithography—which ASML does sell to China under strict licenses—to EUV is a chasm that cannot be bridged by theory or leaked documents alone.
The ‘Chinese Wall’ of Human Intelligence
Beyond the hardware, ASML has implemented a strict internal security protocol to prevent the leak of intellectual property. Recognizing that human capital is often the primary vector for corporate espionage, the company established a rigid separation of personnel.
Fouquet revealed that ASML deliberately partitions its workforce. Employees with access to EUV technology, documentation, and specialized training are kept entirely separate from those operating in regions where the technology is banned. This “Chinese Wall” ensures that staff based in China are not trained in EUV processes and do not have access to the blueprints required to build or maintain the machines.
Despite these measures, the company remains a target. Reports have surfaced regarding former ASML engineers in China attempting to reconstruct the technology, and San Francisco-based startup Substrate—backed by disciples of billionaire Peter Thiel—has claimed it can build a rival lithography system. However, Fouquet remains confident, noting that “facts indicate extremely little, if any, progress” in these efforts.
An Unforeseen AI Revolution
While ASML has mastered the art of security, it admits it was caught off guard by the sheer velocity of the AI explosion. The transition from AI as a theoretical concept to the ubiquity of ChatGPT created a demand spike that has left the company struggling to keep pace.
The “Massive Four” of American tech—Microsoft, Meta, Amazon, and Google—have allocated over $600 billion toward AI infrastructure this year alone. This capital influx has pushed ASML’s valuation to over $530 billion, making it the most valuable company in Europe. Yet, the CEO admits the scale was unexpected.
“Did we anticipate it? No,” Fouquet admitted, describing a surreal environment where the company must constantly verify the reality of the demand. This surge has led ASML to warn that the global supply of high-end chips may remain insufficient for years to come, as the lead time for producing new EUV machines remains prohibitively long.
| Feature | DUV (Deep Ultraviolet) | EUV (Extreme Ultraviolet) |
|---|---|---|
| Primary Use | Standard semiconductors | Advanced AI & <7nm chips |
| Availability in China | Limited/Licensed | Strictly Prohibited |
| Complexity | High | Extreme (Global Monopoly) |
| Approx. Cost | Tens of millions | $200M – $400M+ |
The Geopolitical Stakes
The battle over EUV is not merely a corporate struggle; it is a matter of national security. The ability to produce 3nm or 2nm chips determines who leads in quantum computing, autonomous weaponry, and advanced surveillance. By controlling the “bottleneck” of the entire industry, ASML provides the West with a powerful lever of diplomatic and economic pressure.
However, this monopoly brings its own risks. ASML is now caught in the middle of a tug-of-war between the Dutch government, the U.S. Department of Commerce, and the Chinese Ministry of Commerce. Any shift in export controls can instantly erase billions in projected revenue, yet any lapse in security could shift the global balance of power.
The next critical milestone for the industry will be the widespread deployment of “High-NA” EUV machines—the next generation of lithography that allows for even smaller, more efficient transistors. ASML is currently shipping these first units to select partners, and the company’s ability to keep this new tier of technology out of the hands of unauthorized actors will be the ultimate test of its security apparatus.
