ASML holds a 100% monopoly over Extreme Ultraviolet (EUV) lithography systems. This analysis covers the company's €27.6 billion business model, extreme customer concentration, and the physical and geopolitical barriers that make its semiconductor hegemony virtually impossible to replicate.

ASML Holding N.V. in Veldhoven, Netherlands is the sole manufacturer of Extreme Ultraviolet (EUV) lithography systems — the only machines capable of etching sub-7nm transistors onto silicon wafers. Without ASML, progress in AI, high-performance computing, and mobile processors would stop.
FY2023: Net sales €27.56B, net income €7.84B, net margin 28.4%, gross margin 51.3%. Shipped 53 EUV systems and 396 DUV systems. Average selling price: standard EUV €180-220M, High-NA EUV >$350M. No other company can charge this because no other company can supply the product.
A CO2 laser fires 50,000 pulses/second at microscopic tin droplets in a vacuum chamber. The first pulse flattens the droplet; the second vaporizes it into plasma at 220,000°C. This plasma emits 13.5nm EUV photons — a wavelength that glass absorbs, so ASML routes the light via Carl Zeiss Bragg mirrors (100 alternating atomic layers of silicon and molybdenum, ~70% reflectivity each). Less than 2% of original light reaches the wafer. The system etches features at 13.5nm — equivalent to aiming a flashlight from Earth and hitting a 50-cent coin on the Moon.
All three co-funded ASML's R&D via a 2012 Customer Co-Investment Program, taking equity stakes to secure future supply.
Since 2019, ASML blocked from exporting EUV to China under US pressure. In 2023-2024, restrictions expanded to advanced DUV systems. China represented 45%+ of ASML sales in some quarters as buyers rushed to stockpile older equipment. Long-term: systemic decoupling threatens a substantial portion of legacy revenue.
