Decades of R&D investment in extreme ultraviolet lithography created a monopoly position where the entire semiconductor industry depends on a single equipment provider to continue shrinking transistors.
A structural look at how a Dutch company became the sole supplier of the world's most advanced chipmaking equipment.
Introduction
ASML makes the machines that make advanced chips. Without ASML equipment, there would be no leading-edge smartphones, data center processors, or AI accelerators. The company occupies one of the most unusual competitive positions in any industry: sole supplier of a technology essential to modern electronics.
Few people outside the semiconductor industry recognize ASML's name, yet the company's technology is essential to products billions of people use daily. This gap between obscurity and importance reflects the company's position deep in the supply chain, far from consumer-facing products.
Understanding ASML's arc reveals how technical excellence sustained over decades can create monopoly positions that would be nearly impossible to replicate. The barriers are not legal or regulatory—they are purely technical and accumulated.
The Long-Term Arc
How did ASML survive its early years against Nikon and Canon?
ASML began in 1984 as a joint venture between Philips and a Dutch company. The early years were difficult—the company struggled against established competitors like Nikon and Canon in lithography equipment. Survival required continuous improvement against well-funded rivals.
Lithography machines use light to print circuit patterns on silicon wafers—a fundamental step in chip manufacturing. Each generation of smaller circuits requires more precise lithography. ASML focused on this increasingly demanding technology, gradually improving capabilities.
What drove ASML's rise to technology leadership through the 1990s and 2000s?
Through the 1990s and 2000s, ASML steadily gained market share through technology leadership. The company invested heavily in R&D, often partnering with customers and suppliers to advance capabilities. This collaborative approach enabled innovations that internal development alone might not have achieved.
Critical decisions to invest in extreme ultraviolet (EUV) lithography began in the 1990s. EUV uses light with wavelengths far shorter than conventional lithography, enabling smaller circuit patterns. This technology required decades of development, billions of investment, and collaboration across the industry.
What makes EUV lithography essential to advanced chips?
EUV lithography reached commercial viability around 2018 after over two decades of development. ASML is the only company that successfully productized EUV. The technology is essential for manufacturing the most advanced chips—anything below 7 nanometer process nodes requires EUV. No alternatives exist.
This monopoly position emerged from sustained investment, accumulated expertise, and supply chain integration that competitors did not or could not match. The barriers are technical: replicating ASML's capabilities would require years of development, billions in investment, and relationships with specialized suppliers who already work with ASML.
Which chipmakers depend on ASML today?
Today, ASML supplies lithography equipment to every major chipmaker. Intel, Samsung, and TSMC all depend on ASML machines for their most advanced processes. The company's order book extends years into the future; demand exceeds production capacity. EUV machines cost over $150 million each and generate extraordinary margins.
The strategic importance of ASML has drawn government attention. Export controls limit EUV sales to certain countries, particularly China. ASML has become essential infrastructure for semiconductor independence, elevating the company's geopolitical significance beyond its commercial position.
Structural Patterns
- Technical Monopoly — ASML is the sole supplier of EUV lithography. This position resulted from technology development, not market manipulation or regulatory protection.
- Decades of Development — EUV required over twenty years of R&D. This timeframe creates barriers that new entrants cannot compress. Catching up would take decades.
- Supply Chain Integration — ASML coordinates specialized suppliers worldwide who provide components no one else makes. This supply chain is itself a competitive advantage.
- Essential Infrastructure — Advanced chips cannot be manufactured without ASML equipment. This essential nature creates pricing power and demand stability.
- Collaborative Development — Partnerships with customers, research institutions, and suppliers enabled innovations that isolated development could not achieve.
- Continuous Investment — R&D spending remains substantial even with monopoly position. Leadership requires continuous advancement as chip requirements evolve.
Key Turning Points
1984: Company Formation — Beginning as a Philips joint venture established the foundation. Survival through early challenges required focus and persistence that would characterize the company's development.
1995: EUV Research Begins — Committing to EUV development when commercial viability was uncertain demonstrated willingness to make long-term investments. This decision decades ago enabled today's monopoly.
2012: Carl Zeiss Partnership — Acquiring a stake in Carl Zeiss's semiconductor optics division secured essential mirror technology. The partnership ensured access to components no one else could provide.
2017: First EUV Commercial Shipments — Delivering commercial EUV systems validated decades of development. Production ramp began the revenue and profit growth that continues today.
2020s: Export Controls — Government restrictions on EUV sales to China elevated ASML's strategic importance. The company became essential infrastructure for national semiconductor independence.
Risks and Fragilities
Export controls limit market access. Restrictions on sales to China reduce potential revenue and create geopolitical complexity. Further restrictions could affect other markets or create pressure for alternative development.
Technology transitions could reduce ASML's relevance if fundamentally different approaches to chipmaking emerged. While no alternatives to lithography-based manufacturing exist currently, technological disruption cannot be ruled out over long timeframes.
Customer concentration creates dependency. A small number of chipmakers represent the majority of revenue. Their investment cycles and strategic decisions directly affect ASML's results.
What Investors Can Learn
- Technical excellence can create monopolies — When barriers are purely technical and accumulated over decades, monopoly positions can emerge and persist.
- Long development cycles create barriers — Technologies requiring decades to develop cannot be quickly replicated. Time itself becomes a moat.
- Essential infrastructure commands pricing power — Products that customers cannot operate without enable pricing that discretionary products cannot achieve.
- Supply chain integration provides advantage — Coordinating specialized suppliers creates barriers beyond the technology itself.
- Strategic importance has implications — Companies essential to national priorities face both protection and constraints from government attention.
- Collaborative development can accelerate innovation — Partnerships with customers and suppliers can enable advances that isolated development cannot.
