THE COMPANY THAT TOOK 20 YEARS TO BUILD A MACHINE ITS CUSTOMERS COULDN'T REPLACE
It costs hundreds of millions of dollars, takes years to develop, and is so complicated that the company selling it has no commercial rival.
The strange part?
The customers aren't buying the machine because they particularly want ASML.
They're buying it because they need what the machine can do.
And without it, making the world's most advanced chips becomes dramatically harder.
THE MACHINE DOESN'T MAKE CHIPS
ASML doesn't manufacture iPhones.
It doesn't design NVIDIA GPUs.
It doesn't produce AMD processors.
It makes something much less visible:
lithography machines.
These machines essentially project extremely precise patterns onto silicon wafers.
Those patterns become the tiny structures that eventually form transistors.
And the smaller and more precise those patterns can be, the more advanced the chip can become.
ASML's EUV systems use extreme ultraviolet light to print some of the smallest features used in advanced semiconductor manufacturing.
THEN ASML TRIED TO DO SOMETHING THAT SOUNDED ALMOST IMPOSSIBLE
The company wanted to use a wavelength of light that was dramatically shorter than the light used in conventional lithography.
The technology became known as:
EUV — Extreme Ultraviolet.
The problem was that EUV light is incredibly difficult to work with.
You can't simply shine it through an ordinary lens.
The entire system requires extraordinarily precise optics, light generation, vacuum systems, wafer positioning and software.
And all of those technologies have to work together.
A machine can fail if just one part isn't precise enough.
IT TOOK DECADES
The history of EUV didn't begin with ASML suddenly building a machine in a factory.
Research into EUV lithography stretches back to the 1980s.
ASML's own history describes a development journey involving laboratories in Japan, the United States and the Netherlands before the technology eventually reached commercial manufacturing.
ASML shipped its first EUV prototype to a customer research facility in 2010.
Production-ready systems followed years later.
In 2016, customers began ordering ASML's first production-ready EUV systems.
By 2020, EUV had entered high-volume manufacturing.
So when people say EUV took roughly 20 years to develop, they're describing a development journey that stretched across many years of research, engineering and commercialization — not a machine that ASML simply designed from scratch in a single 20-year project.
BILLIONS WENT INTO THE BET
ASML didn't build this technology alone.
Its EUV development involved a huge network of suppliers, research organizations and technology partners.
One important move came in 2013, when ASML acquired Cymer, a company specializing in the light source technology needed for EUV.
That helped accelerate the development of commercially viable EUV systems.
The money involved was enormous.
ASML's 2025 annual report shows that the company spent €4.7 billion on R&D in 2025 alone across its technology portfolio.
EUV itself required years of development before customers were willing to commit billions of dollars to fabs built around the technology.
THEN THE MACHINE BECAME TOO IMPORTANT TO IGNORE
By 2018, ASML says its customers had begun making major investments in EUV technology.
They weren't simply buying one machine.
They were building entire manufacturing strategies around it.
In 2019, the first commercial product using EUV-enabled manufacturing was released.
By December 2020, ASML had shipped its 100th EUV system.
By the end of 2021, 127 of its latest-generation EUV machines were operating at customer locations around the world.
The machine had moved from:
Science experiment
to
industrial technology
to
critical semiconductor infrastructure.
AND THEN SOMETHING VERY UNUSUAL HAPPENED
ASML became the only company in the world manufacturing EUV lithography systems.
ASML itself states this in its 2025 annual report.
That doesn't mean chipmakers have literally no other lithography equipment.
They use other technologies too, including DUV systems.
But for the most advanced layers of many leading-edge chips, EUV has become extremely important.
And ASML is currently the sole commercial supplier of EUV systems.
That creates an extraordinary position.
The companies designing the world's most advanced chips depend on a machine made by another company.
THE MACHINE IS ABSURDLY EXPENSIVE
The newest High-NA EUV machines are entering another level entirely.
Reuters reported in September 2026 that ASML's High-NA EUV machines cost around $400 million each.
And customers are still buying them.
Why?
Because the machine isn't being judged like an ordinary piece of factory equipment.
A company isn't asking:
"Can we find a cheaper machine?"
It's asking:
"Can this machine help us manufacture the next generation of chips?"
That's a completely different purchasing decision.
ASML DOESN'T BUILD EVERYTHING ITSELF
This is one of the most interesting parts of the business.
An ASML EUV machine is not simply a collection of components manufactured inside one Dutch factory.
It depends on a vast network of specialized suppliers.
ASML describes its supplier network as an essential part of its ability to develop and manufacture its systems.
The company also notes that many EUV components are highly specialized and that some are single-sourced or difficult to source from multiple suppliers.
So ASML's advantage isn't just:
"We have a secret machine."
It's closer to:
"We have spent decades coordinating an ecosystem capable of building this machine."
THAT MAKES THE BUSINESS HARD TO COPY
Imagine a competitor deciding tomorrow:
"We'll build our own EUV machine."
They don't just need one brilliant engineer.
They need:
And then they need the entire system to work reliably inside a semiconductor factory.
That's an enormous barrier.
The difficulty isn't simply copying the appearance of the machine.
It's reproducing the knowledge accumulated around it.
THE CUSTOMERS ALSO BECOME PART OF THE SYSTEM
ASML works closely with major chipmakers to develop and improve its machines.
The customer doesn't simply receive a giant box and walk away.
These systems need installation, qualification, maintenance, upgrades and continuous optimization.
ASML's 2025 annual report notes that its growing installed base requires extensive customer-support capabilities, including shipment, maintenance, servicing and upgrades.
That creates another layer of dependence.
The relationship becomes:
Machine
↓
Software
↓
Service
↓
Upgrades
↓
Manufacturing knowledge
↓
Next-generation machine
The product becomes a long-term ecosystem.
THEN ASML BUILT THE NEXT MACHINE
EUV itself wasn't the end.
ASML began developing High-NA EUV, a more advanced version designed to print even smaller features.
The first High-NA system was shipped in 2023.
In 2025, ASML reported that it had shipped its first High-NA system in full specification to its first customer.
Reuters reported in September 2026 that major chipmakers including TSMC, Samsung, SK Hynix and Intel were embracing the technology, with High-NA systems priced around $400 million.
The cycle continues:
Develop
↓
Test
↓
Customers invest
↓
Factories adapt
↓
Technology becomes essential
↓
Develop the next generation
THIS IS WHY THE BUSINESS IS SO POWERFUL
ASML doesn't need to sell a consumer product to billions of people.
It doesn't need an app on your phone.
It doesn't need a famous logo on a laptop.
It sells an extraordinarily complicated piece of infrastructure to a very small number of customers.
But those customers are themselves responsible for producing enormous amounts of the world's most important chips.
So one machine company sits deep inside an enormous technology chain:
ASML
↓
Lithography
↓
TSMC / Samsung / Intel and other chipmakers
↓
Advanced processors and memory
↓
AI systems / smartphones / computers / data centers
↓
Products used around the world
THE REAL MOAT ISN'T THE MACHINE
This is the part most people miss.
ASML's biggest advantage isn't simply owning patents or having a large factory.
It's the accumulated complexity.
Decades of research.
Thousands of engineers.
Specialized suppliers.
Customer collaboration.
Manufacturing experience.
Software.
Optics.
Light sources.
Precision engineering.
Data from machines already operating in factories.
Each generation builds on the previous one.
That makes the next competitor's starting point incredibly far behind.
MAACAT PERSPECTIVE
Some businesses become powerful because millions of people buy their products.
ASML represents a different model.
Very few customers.
Very expensive machines.
Extremely high technical barriers.
And enormous importance to the companies that buy them.
The machine itself is almost invisible to consumers.
But if you own a smartphone, use AI, run a computer or depend on modern electronics, the technology chain behind your device may eventually lead back to one of these machines.
That's the strange economics of infrastructure.
You don't have to sell something to everyone.
Sometimes it is enough to build one piece of technology that everyone else needs.
