ASML became the unchallengeable monopoly supplier of EUV lithography machines by betting early on an unproven technology backed by a US government-led public-private partnership.
Key Takeaways
Each EUV machine contains over 100,000 components, ships via 40 freight containers and 3 cargo planes, and costs more than $120 million.
EUV generates 13.5nm light by firing a laser at falling tin droplets, then reflecting the beam through mirrors so precise that Germany-scaled versions would show millimeter-level flaws.
Without EUV, manufacturing a 5nm node would require roughly 100 patterning steps; EUV collapses 3-4 cycles into one at the 7nm node.
ASML’s modular outsourcing strategy, mocked by German engineers, became its core advantage: faster on-site repairs cut customer downtime and won IBM’s first major order over Nikon.
The EUV LLC public-private partnership (Intel-led, DOE-backed, $270M over six years) rescued the underlying research program from budget cuts and locked ASML into the development path.
