The semiconductor lithography business operates on economics unlike almost any other industry. ASML’s model reveals how physics constraints, yield mathematics, and ecosystem dependencies combine to create what may be the most structurally protected revenue stream in technology.
Lithography economics rest on a simple but brutal reality: smaller circuits require exponentially more expensive machines, but they make chips exponentially cheaper to produce per transistor.
This is the engine that has driven Moore’s Law for decades. CEO Christophe Fouquet explains it directly: “Moore’s Law says that we need to continue to drive costs down. There is a belief that if you drive costs down, you create more opportunity, so we need to be part of this game.”
The customer is not buying a machine. They are buying access to the next node and the cost reductions that come with it.
Why This Matters
ASML builds the most expensive machines in semiconductor fabs and the only ones that reliably make chips cheaper. Each generation does not just cost more but delivers proportionally more value. The company must keep total chip costs declining to maintain demand growth.
If lithography costs rose faster than the value it creates, customers would slow adoption and the entire semiconductor industry would stall. ASML’s pricing power is real but bounded by the need to keep Moore’s Law economics functioning.
The Monopoly Position
ASML is the only company in the world capable of building EUV systems. This monopoly position could theoretically support even higher pricing, but the company operates under a fundamental constraint: the monopoly is over machine supply, not the ultimate chip market.
The economics of lithography ultimately rest on a single proposition: ASML’s machines cost more than anything else in a fab, but they are also the only path to chips that cost less per transistor. As long as that equation holds, the business model remains unassailable.
