ASML
The only company in the world that can mass-produce EUV (Extreme Ultraviolet) lithography machines, and a one-stop supplier of the most critical equipment in semiconductor manufacturing.
A global monopoly in EUV lithography machines, with no competitor able to produce a mass-producible EUV system. Decades of precision optical and mechanical engineering, complex system integration capabilities, and deep ties with top-tier supply chains such as Zeiss form a technological moat that cannot be replicated in the short term.
Company Overview
ASML was founded in 1984 as a joint venture between Philips, the Dutch electronics giant, and ASM International, headquartered in Veldhoven, the Netherlands.
ASML's rise in the lithography machine market is a classic case of a "technology bet." In the 1990s, when Japan's Nikon and Canon held an absolute advantage in the DUV (deep ultraviolet) lithography machine market, ASML bet on the EUV (extreme ultraviolet) lithography technology route, which was still at the theoretical stage. After nearly 20 years of overcoming technical hurdles and tens of billions of U.S. dollars in R&D investment, ASML delivered the world's first production-ready EUV lithography machine in 2015, completely transforming the competitive landscape of the semiconductor equipment industry. Today, all chips manufactured with advanced process nodes at 7nm and below must be produced using ASML's EUV lithography machines.
Core Business
EUV (Extreme Ultraviolet) Lithography Systems | Core Profit Source (Revenue Share ~50%+)
EUV lithography machines are among the most complex single machines in the world. A single EUV lithography machine weighs approximately 180 tons, contains over 100,000 components, requires 40 shipping containers for transport, and costs more than €300 million.
- Technical Principle: Uses extreme ultraviolet light with a wavelength of only 13.5nm to "etch" chip design patterns onto silicon wafers through a series of extremely precise reflective mirrors (mirror surface roughness must be controlled at the atomic level).
- Core Barrier: EUV lithography machines must generate extreme ultraviolet light in a high-vacuum environment, with light source power reaching hundreds of watts. Only ASML (through its integration with Cymer) can manufacture light source systems at this level.
DUV (Deep Ultraviolet) Lithography Systems
Although EUV represents the most cutting-edge technology, DUV (193nm wavelength) lithography machines remain the primary equipment for mature process nodes and certain special processes. ASML holds a market share of over 60% in the DUV market, competing with Japan's Nikon and Canon.
High-NA EUV (Next-Generation Systems)
ASML is vigorously advancing High-NA (High Numerical Aperture) EUV technology, which is essential for achieving 2nm and below process nodes. High-NA EUV lithography machines feature a more powerful optical projection system, with a unit price potentially exceeding €400 million. Intel has already taken the lead in placing orders.
Technical Moat
EUV Monopoly Position: ASML is the only company in the world capable of designing and manufacturing high-volume-manufacturing EUV lithography systems. Its EUV technology R&D spanned nearly 20 years, involving collaboration across more than 5,000 suppliers globally, including Germany's Zeiss providing specialized reflective mirrors and America's Cymer supplying the light source system. A supply chain ecosystem of this magnitude cannot be replicated in the short term.
Capital and Patent Barriers: ASML invests over €4 billion in R&D annually and has accumulated tens of thousands of core patents. EUV lithography technology involves the intersection of cutting-edge expertise across multiple disciplines, including optics, precision mechanics, plasma physics, and vacuum systems.
Strategic Position from Export Controls: Due to the irreplaceable role of EUV lithography machines in advanced-node chip manufacturing, their exports are subject to strict controls by both the Dutch and U.S. governments. This makes ASML more than just a commercial company—it has become a core piece in the global semiconductor geopolitical chess game.

Financials & Growth
| Metric | Data |
|---|---|
| Revenue (2024) | Approx. €28 billion |
| Net Profit Margin | Approx. 28% |
| Backlog Orders | Over €35 billion |
| Growth Drivers | Continued advancement of advanced process nodes → EUV demand only increases; High-NA adoption → further increase in unit price |
Risks and Summary
Key Risks:
- Geopolitical Risk: Export restrictions on China have caused ASML to lose part of its market and face uncertainty over the continued tightening of export policies.
- Approaching Technical Limits: The physical limits of EUV are fast approaching, and whether an entirely new technology roadmap (such as high-energy electron-beam direct writing) will be needed remains uncertain.
Core Industry Value: ASML is the "crown jewel" at the very top of the semiconductor manufacturing chain. If TSMC is the "chip-making factory," then ASML is the "access card to the factory." Without ASML's EUV lithography machines, no company can manufacture advanced chips below 7nm. It is the ultimate gatekeeper of the hardware foundation of the entire digital world.
