Extreme Ultraviolet (EUV) lithography stands as the cornerstone of modern semiconductor manufacturing, an indispensable technology pushing the boundaries of miniaturization to unprecedented sub-nanometer scales. By harnessing light with an incredibly short wavelength of 13.5 nanometers, EUV systems enable the creation of circuit patterns so fine that they are invisible to the naked eye, effectively extending Moore's Law and ushering in an era of ever more powerful and efficient microchips. This revolutionary process is not merely an incremental improvement; it is a fundamental shift that underpins the development of cutting-edge artificial intelligence, high-performance computing, 5G communications, and autonomous systems.
As of October 2025, EUV lithography is firmly entrenched in high-volume manufacturing (HVM) across the globe's leading foundries. Companies like Taiwan Semiconductor Manufacturing Company (TSMC) (NYSE: TSM), Samsung Electronics Co., Ltd. (KRX: 005930), and Intel Corporation (NASDAQ: INTC) are leveraging EUV to produce chips at advanced nodes such as 7nm, 5nm, and 3nm, with eyes already set on 2nm and beyond. The immediate significance of EUV lies in its enablement of the next generation of computing power, providing the foundational hardware necessary for complex AI models and data-intensive applications, even as the industry grapples with the immense costs and technical intricacies inherent to this groundbreaking technology.
The Microscopic Art of Chipmaking: Technical Prowess and Industry Response
EUV lithography represents a monumental leap in semiconductor fabrication, diverging significantly from its Deep Ultraviolet (DUV) predecessors. At its core, an EUV system generates light by firing high-powered CO2 lasers at microscopic droplets of molten tin, creating a plasma that emits the desired 13.5 nm radiation. Unlike DUV, which uses transmissive lenses, EUV light is absorbed by most materials, necessitating a vacuum environment and an intricate array of highly polished, multi-layered reflective mirrors to guide and focus the light onto a reflective photomask. This mask, bearing the circuit design, then projects the pattern onto a silicon wafer coated with photoresist, enabling the transfer of incredibly fine features.
The technical specifications of current EUV systems are staggering. Each machine, primarily supplied by ASML Holding N.V. (NASDAQ: ASML), is a marvel of engineering, capable of processing hundreds of wafers per hour with resolutions previously unimaginable. This capability is paramount because, at sub-nanometer nodes, DUV lithography would require complex and costly multi-patterning techniques (e.g., double or quadruple patterning) to achieve the required resolution. EUV often allows for single-exposure patterning, significantly simplifying the fabrication process, reducing the number of masking layers, cutting production time, and improving overall wafer yields by minimizing defect rates. This simplification is a critical advantage, making the production of highly complex chips more feasible and cost-effective in the long run.
The semiconductor research community and industry experts have largely welcomed EUV's progress with a mixture of awe and relief. It's widely acknowledged as the only viable path forward for continuing Moore's Law into the sub-3nm era. The initial reactions focused on the immense technical hurdles overcome, particularly in developing stable light sources, ultra-flat mirrors, and defect-free masks. With High-Numerical Aperture (High-NA) EUV systems, such as ASML's EXE platforms, now entering the deployment phase, the excitement is palpable. These systems, featuring an increased numerical aperture of 0.55 (compared to the current 0.33 NA), are designed to achieve even finer resolution, enabling manufacturing at the 2nm node and potentially beyond to 1.4nm and sub-1nm processes, with high-volume manufacturing anticipated between 2025 and 2026.
Despite the triumphs, persistent challenges remain. The sheer cost of EUV systems is exorbitant, with a single High-NA machine commanding around $370-$380 million. Furthermore, the light source's inefficiency, converting only 3-5% of laser energy into usable EUV photons, results in significant power consumption—around 1,400 kW per system—posing sustainability and operational cost challenges. Material science hurdles, particularly in developing highly sensitive and robust photoresist materials that minimize stochastic failures at sub-10nm features, also continue to be areas of active research and development.

The advent and widespread adoption of EUV lithography are profoundly reshaping the competitive landscape for AI companies, tech giants, and startups alike. At the forefront, major semiconductor manufacturers like TSMC (NYSE: TSM), Samsung Electronics Co., Ltd. (KRX: 005930), and Intel Corporation (NASDAQ: INTC) stand to benefit immensely. These companies, by mastering EUV, solidify their positions as the primary foundries capable of producing the most advanced processors. TSMC, for instance, began rolling out an EUV Dynamic Energy Saving Program in September 2025 to optimize its substantial power consumption, highlighting its deep integration of the technology. Samsung is aggressively leveraging EUV with the stated goal of surpassing TSMC in foundry market share by 2030, having brought its first High-NA tool online in Q1 2025. Intel, similarly, deployed next-generation EUV systems in its US fabs in September 2025 and is focusing heavily on its 1.4 nm node (14A process), increasing its orders for High-NA EUV machines.
The competitive implications for major AI labs and tech companies are significant. Companies like NVIDIA Corporation (NASDAQ: NVDA), Alphabet Inc. (NASDAQ: GOOGL), and Apple Inc. (NASDAQ: AAPL), which design their own high-performance AI accelerators and mobile processors, are heavily reliant on these advanced manufacturing capabilities. Access to sub-nanometer chips produced by EUV enables them to integrate more transistors, boosting computational power, improving energy efficiency, and packing more sophisticated AI capabilities directly onto silicon. This provides a critical strategic advantage, allowing them to differentiate their products and services in an increasingly AI-driven market. The ability to leverage these advanced nodes translates directly into faster AI model training, more efficient inference at the edge, and the development of entirely new classes of AI hardware.
Potential disruption to existing products or services is evident in the accelerating pace of innovation. Older chip architectures, manufactured with less advanced lithography, become less competitive in terms of performance per watt and overall capability. This drives a continuous upgrade cycle, pushing companies to adopt the latest process nodes to remain relevant. Startups in the AI hardware space, particularly those focused on specialized AI accelerators, also benefit from the ability to design highly efficient custom silicon. Their market positioning and strategic advantages are tied to their ability to access leading-edge fabrication, which is increasingly synonymous with EUV. This creates a reliance on the few foundries that possess EUV capabilities, centralizing power within the semiconductor manufacturing ecosystem.
Furthermore, the continuous improvement in chip density and performance fueled by EUV directly impacts the capabilities of AI itself. More powerful processors enable larger, more complex AI models, faster data processing, and the development of novel AI algorithms that were previously computationally infeasible. This creates a virtuous cycle where advancements in manufacturing drive advancements in AI, and vice versa.
