As of November 2025, ASML's innovations are more critical than ever, dictating the pace of technological advancement and shaping the competitive landscape for chip manufacturers worldwide.
Precision Engineering: The Technical Marvels of Modern Lithography
The journey of creating a microchip begins with lithography, a process akin to projecting incredibly detailed blueprints onto a silicon wafer. This involves coating the wafer with a light-sensitive material (photoresist), exposing it to a pattern of light through a mask, and then etching the pattern into the wafer. This complex sequence is repeated dozens of times to build the multi-layered structures of an integrated circuit. ASML's dominance stems from its mastery of Deep Ultraviolet (DUV) and, more crucially, Extreme Ultraviolet (EUV) lithography.
EUV lithography represents a monumental leap forward, utilizing light with an incredibly short wavelength of 13.5 nanometers – approximately 14 times shorter than the DUV light used in previous generations. This ultra-short wavelength allows for the creation of features on chips that are mere nanometers in size, pushing the boundaries of what was previously thought possible. ASML is the sole global manufacturer of these highly sophisticated EUV machines, which employ a complex system of mirrors in a vacuum environment to focus and project the EUV light. This differs significantly from older DUV systems that use lenses and longer wavelengths, limiting their ability to resolve the extremely fine features required for today's most advanced chips (7nm, 5nm, 3nm, and upcoming sub-2nm nodes). Initial reactions from the semiconductor research community and industry experts heralded EUV as a necessary, albeit incredibly challenging, breakthrough to continue Moore's Law, overcoming the physical limitations of DUV and multi-patterning techniques.
Further solidifying its leadership, ASML is already pushing the boundaries with its next-generation High Numerical Aperture (High-NA) EUV systems, known as EXE platforms. These machines boast an NA of 0.55, a significant increase from the 0.33 NA of current EUV systems. This higher numerical aperture will enable even smaller transistor features and improved resolution, effectively doubling the density of transistors that can be printed on a chip. While current EUV systems are enabling high-volume manufacturing of 3nm and 2nm chips, High-NA EUV is critical for the development and eventual high-volume production of future sub-2nm nodes, expected to ramp up in 2025-2026. This continuous innovation ensures ASML remains at the forefront, providing the tools necessary for the next wave of chip advancements.
ASML's Indispensable Role: Shaping the Semiconductor Competitive Landscape
ASML's technological supremacy has profound implications for the entire semiconductor ecosystem, directly influencing the competitive dynamics among the world's leading chip manufacturers.
