ASML is the dominant supplier of photolithography machines for integrated circuit production. Founded in 1984 as a joint venture between Philips and ASM International, it inherited Philips’ stalled lithography project and initially had no market-ready product. Its first machine, the PAS 2000, failed commercially and technically. Success came with the PAS 5500 in the early 1990s. By 2002, ASML was the largest lithography supplier. It now leads in extreme ultraviolet (EUV) lithography—the only viable method for manufacturing the most advanced chips—and completed EUV machine development in the late 2010s. Competitors included Canon, Nikon, Ultratech, MKS Instruments, Lam Research, and Cadence Design Systems.
ASML is a Dutch lithography machine manufacturer founded in 1984 to finish Philips’ stalled in-house project. It solves the problem of printing ever-smaller transistor features onto silicon, enabling Moore’s Law to continue.
How it works
ASML builds photolithography machines that project circuit patterns onto silicon wafers using light. Its modular design outsources subsystems while retaining integration control. It prioritised serviceability and field-upgradability over monolithic in-house engineering.
What works
ASML’s outsourcing-plus-integration model worked. Its PAS 5500 succeeded in the early 1990s. By 2002 it was the largest lithography supplier. It now dominates EUV—the only technology capable of producing the most advanced chips.
What does not
ASML did not deliver a market-ready product at launch. The PAS 2000 failed technically and commercially. Its EUV development took over a decade and was not completed until the late 2010s—far past initial projections.
What it changes
ASML changed who controls the bottleneck in chipmaking. It shifted lithography from a competitive, multi-vendor market—where Canon and Nikon held share—to a de facto monopoly on advanced nodes, enforced by physics, complexity, and integration lock-in.
Is it worth your time
Yes—if you work in semiconductor manufacturing, equipment procurement, or chip design. ASML’s machines are not optional infrastructure but mandatory gatekeepers for sub-7nm nodes.
