China’s EUV lags ASML 2004 claims semiconductor gap
The Race for Light: China’s Ambition to Master Semiconductor Lithography
The journey to manufacturing the world’s most advanced chips is defined by a single, incredibly complex bottleneck: photolithography. This process, which uses light to etch intricate patterns onto silicon wafers, is arguably the most technologically demanding step in semiconductor production. And when looking at the global landscape, the ability to produce these essential lithography tools places the semiconductor industry squarely at the epicenter of a technological race.
In an analysis of the industry’s trajectory, some experts noted a striking comparison: China’s capacity to produce lithography tools was, at one point, comparable to that of market leader ASML back in 2004. This comparison highlights the monumental gap between current capabilities and future ambitions. While the overall semiconductor industry remains firmly behind Western counterparts, the path to catching up is paved with the development and mass production of these highly specialized tools.
Photolithography is inherently challenging. It requires not only the creation of extraordinarily complex machines, but also perfect positional accuracy, resolution, and uniformity. A successful lithography system must achieve these demanding requirements without compromise—a machine that offers high resolution yet guarantees predictable uptime and defect density.
Historically, only a handful of companies managed to survive the complexity of this field, with ASML standing out as the undisputed market leader, particularly in cutting-edge technologies like EUV lithography. This dominance is built on decades of relentless innovation and manufacturing refinement.
As China has pursued semiconductor self-sufficiency, there has been a concerted effort to build a parallel ecosystem. Various Chinese entities, including Shanghai Micro Electronics Equipment (SMEE), AMIES, SiCarrier, and Naura, have developed world-class tools for chemical processing and deposition. However, the creation of a competitive lithography machine capable of mass production on modern nodes remains the ultimate hurdle.
SMEE, one of the most established Chinese manufacturers of lithography tools, has reported advancements, including the introduction of an immersion DUV lithography system. Reports indicated that this system was capable of processing chips on nodes down to 28nm, suggesting a breakthrough in domestic tool development.
However, the transition from a technological claim to industrial reality is a slower process. While there are reports suggesting that Chinese entities, such as a unit affiliated with SMEE, have begun to mass-produce immersion DUV scanners, these developments have not yet been accompanied by concrete evidence of shipments or formal process qualification by major chipmakers.
For a newly developed tool to move from the lab to mass production, a rigorous qualification process is necessary. This involves chipmakers testing the new equipment, developing recipes, and confirming performance against established standards. Experts suggest that even once a breakthrough scanner is qualified, integrating it into an existing fabrication flow can take at least two years, and potentially much longer, before it reaches full deployment.
Ultimately, without tangible indicators of mass production and customer adoption of these advanced immersion scanners, the market position remains anchored by the established leaders. The race for lithography mastery is complex, demanding not just technical innovation, but verifiable industrial execution before true parity can be achieved.
