Introduction
In a significant move to challenge the established dominance of ASML in the extreme ultraviolet (EUV) lithography sector, Russia has unveiled plans to develop its own EUV lithography system with an innovative 11.2 nm wavelength technology.
This ambitious project, led by Nikolay Chkhalo, a scientist from the Russian Academy of Sciences’ Institute of Microstructure Physics, aims to create a cost-effective alternative to ASML’s machines, which currently use a 13.5 nm wavelength.
Though Russia is still in the research phase, the goal is to design machines that, while less powerful, can serve smaller-scale manufacturing needs.
Overview of Russia’s EUV Lithography Development Roadmap
Russia’s EUV lithography initiative is a bold step toward developing a domestic solution for semiconductor production. Here are the key points of their ambitious roadmap:
- Alternative Wavelength: The Russian system will utilize an 11.2 nm wavelength, differing from ASML’s 13.5 nm standard, potentially improving resolution and reducing complexity.
- New Technology Approach: The system will employ xenon-powered lasers instead of ASML’s tin-based lasers, marking a significant departure from the industry’s current approach.
- Lower Throughput: The Russian machines will have a throughput of about 37% of ASML’s capacity, producing around 60 200-mm wafers per hour in prototype form, with eventual goals of 60 300-mm wafers per hour.
- Cost-Effective Strategy: The goal is to make lithography equipment cheaper to manufacture, which could democratize access to EUV systems, especially in regions and companies unable to afford ASML’s high-end machines.
- Long Development Timeline: Experts believe it could take over ten years to develop a fully functional lithography ecosystem, from prototype machines to complete production systems.

Background: The EUV Lithography Market and ASML’s Dominance
EUV lithography is critical for advancing semiconductor fabrication, enabling the production of smaller, more powerful chips. ASML, a Dutch company, currently holds a monopoly on EUV lithography machines with its 13.5 nm wavelength technology.
ASML’s machines are used by major chipmakers like TSMC, Samsung, and Intel, who rely on them for manufacturing cutting-edge semiconductor nodes.
While ASML’s EUV systems are essential for producing chips at 7 nm, 5 nm, and smaller process nodes, the systems are incredibly complex and costly.
As a result, their high price tag—often exceeding $100 million per machine—has limited their availability to only the largest semiconductor manufacturers. This has created a gap in the market for more affordable alternatives that could support smaller-scale manufacturers or emerging markets.
Russia Innovative Approach to EUV Lithography
The primary goal of Russia EUV lithography project is to break ASML’s monopoly by introducing a more affordable system with a different approach.
The Russian team plans to develop a system using xenon-powered lasers instead of tin-based lasers, a key part of ASML’s technology. This shift to xenon lasers is expected to lower the complexity of the machines, making them easier and cheaper to build.
11.2 nm Wavelength: The Key to Better Resolution
At the heart of Russia’s strategy is the decision to use an 11.2 nm wavelength for its lithography systems, a significant deviation from the 13.5 nm wavelength used by ASML’s machines.
According to Nikolay Chkhalo, this new wavelength will offer a 20% improvement in resolution compared to ASML’s systems. This improvement could provide advantages in terms of image clarity and precision, which is crucial for chipmakers aiming to push the boundaries of miniaturization.
In addition, the shorter wavelength is expected to simplify the design of optical components, such as mirrors and lenses. The reduced complexity could also help to address one of the key challenges faced by ASML’s systems—optical contamination.
Russian engineers believe that by reducing contamination in critical optical components like collectors and protective pellicles, their system will have a longer operational lifespan.

Step-by-Step Development Plan
Russia’s EUV lithography project is still in its infancy, but Chkhalo and his team have laid out a three-step plan for developing the technology:
- Research and Development: The first step involves researching the fundamental technology behind the 11.2 nm EUV wavelength and testing key components. This phase is crucial to ensure that the technology is viable and that all the necessary elements for lithography, such as lasers, optics, and materials, can be developed successfully.
- Prototype Machine: Once the research phase is complete, the team will move on to building a prototype machine capable of handling 60 200-mm wafers per hour. This stage will focus on creating a functioning EUV lithography system with lower throughput than ASML’s but still suitable for small-scale production.
- Production-Ready System: The final goal is to develop a full-fledged production system capable of handling 60 300-mm wafers per hour. This system would be able to support more advanced manufacturing processes, albeit with reduced speed and throughput compared to ASML’s systems.
Challenges Ahead: New Ecosystem, New Software
The transition to 11.2 nm technology isn’t without its challenges. The shorter wavelength means Russia will need to develop an entirely new ecosystem of components. These will include special mirrors, coatings, mask designs, and photoresists tailored to the 11.2 nm wavelength. Additionally, chip design software tools—especially those used for mask data preparation and optical corrections—will need to be reworked to accommodate the new technology.
These changes to the lithography ecosystem mean that Russia will face significant development hurdles. Lithography is an incredibly complex field, and making advancements will require extensive expertise, testing, and iteration. Experts predict that it could take ten years or more to create a fully functioning EUV lithography system from prototype to production, with the development of supporting tools and processes adding to the timeline.
Lower Throughput but a Niche Opportunity
One of the most significant limitations of Russia’s EUV system is its lower throughput. While ASML’s machines can process up to 120 300-mm wafers per hour, Russia’s prototype system will operate at just 37% of that capacity.
This lower throughput makes the Russian system more suited for niche applications, such as low-volume or specialty chip manufacturing, rather than high-volume production required by leading semiconductor companies.
Despite this limitation, the Russian EUV lithography machine could have significant value in regions or markets where cost is a greater concern than sheer output.
Smaller chipmakers or those in emerging economies may find these systems more affordable, potentially sparking innovation in industries that have been unable to access ASML’s expensive systems.

Conclusion: A Long Road Ahead
Russia EUV lithography project is still in the early stages, but its vision of creating a more affordable, cost-effective alternative to ASML’s technology is an exciting development. While the road to fully functional EUV lithography machines will be long and challenging, the potential for smaller-scale production and new markets makes this an interesting project to watch.
With an ambitious three-step plan and a focus on developing a new ecosystem for EUV technology, Russia hopes to carve out a niche in the highly competitive semiconductor industry. However, the next decade will be critical to see if these plans can come to fruition and challenge the dominance of ASML’s current lithography machines.
