China's EUV Chip Tech Trailing ASML by Two Decades, Analyst Says
A UBS analyst suggests Beijing's domestic lithography efforts are roughly equivalent to ASML's 2004 capabilities.
China's pursuit of semiconductor self-sufficiency faces a steep climb, with its extreme ultraviolet (EUV) lithography progress lagging far behind global standards. A recent industry analysis suggests the gap is measured in decades, not years, complicating Beijing's goal of producing the world's most advanced chips.
Francois-Xavier Bouvignies, an analyst at UBS, claims that China's current EUV technology is at a stage similar to where the Dutch firm ASML stood in 2004. This assessment indicates that while China is investing heavily in domestic alternatives, it remains well behind Western rivals in the specialized equipment required for high-end chip manufacturing.
The EUV Monopoly
EUV lithography is the essential process used to etch the microscopic circuits required for semiconductors below the 7nm threshold. Currently, ASML holds a global monopoly on the production and sale of these highly complex systems. Because these machines are the only viable path to mass-producing the smallest, most efficient transistors, they have become the primary bottleneck in the global semiconductor supply chain.
For China, the challenge is compounded by geopolitical friction. Due to US-led export restrictions, Beijing has been unable to purchase the latest EUV systems from ASML. This blockade has forced the Chinese government to pour resources into domestic research and development to bypass Western dependencies and secure its own supply of advanced logic chips.
Strategic Implications
The inability to close the EUV gap has significant consequences for national security and economic competitiveness. Advanced chips are the foundational hardware for artificial intelligence, high-performance computing, and modern military systems. If China is indeed operating at a technical level from twenty years ago, its ambitions for near-term independence in high-end chip production may be unrealistic.
This technological disparity maintains a strategic advantage for Western firms and their allies, who can continue to iterate on AI hardware while China struggles with the fundamental physics of lithography. The gap suggests that simply increasing funding may not be enough to overcome the deep institutional and technical expertise ASML has cultivated over two decades.
The Path Forward
Industry observers are now watching to see if China can find a workaround or accelerate its development timeline. While Beijing continues to push for domestic breakthroughs, the exact technical specifications of its current prototype systems remain state secrets and have not been independently verified by third-party engineers.
Whether China can leapfrog twenty years of development or if it will remain reliant on older, less efficient DUV (deep ultraviolet) lithography remains the central question for the future of the global chip race.
