Introduction:
Imagine a printing press so advanced that instead of printing ink on paper, it etches billions of tiny transistors onto a silicon wafer the size of your palm. Now imagine this machine as the foundation of every powerful chip that fuels today’s artificial intelligence — from OpenAI’s ChatGPT to Google’s Gemini. That giant is built by ASML, a little-known but critically strategic Dutch company.
If ASML didn’t exist, the digital brains behind today’s AI tools wouldn’t either. No ChatGPT, no Gemini, no AI boom. It’s not just another tech company — it’s the heart of the semiconductor world.

Overview: Five Key Reasons Why ASML is Indispensable
| Key Insight | Why It Matters |
|---|---|
| EUV Lithography Inventor | Only company making Extreme Ultraviolet (EUV) machines crucial for 5nm, 3nm chips. |
| AI’s Secret Enabler | AI chips like NVIDIA’s H100, Google’s TPU, and Apple’s M3 rely on ASML-made chips. |
| Single-Source Monopoly | ASML is the only firm globally that builds EUV machines — others like Canon, Nikon can’t. |
| Geopolitical Flashpoint | Caught in the U.S.-China tech war; blocked from selling EUV to China since 2020. |
| Precision Engineering Marvel | EUV machines have over 100,000 parts and cost €350 million each (~₹3,480 crore). |
ASML: The Company That Redefined Lithography
Founded in 1984 as a joint venture between Philips and ASM International, ASML giant specializes in lithography — a process where light is used to carve intricate patterns onto silicon wafers. These patterns eventually become chips powering phones, laptops, data centers, and now, AI models.
ASML’s biggest leap came in the late 1990s when it shifted focus from Deep Ultraviolet (DUV) to Extreme Ultraviolet (EUV). DUV had a wavelength of 193 nanometers, while EUV operates at just 13.5 nanometers — small enough to enable chip sizes under 7nm, unlocking massive performance and energy efficiency.
EUV Machines: The Giant Behind Tiny Transistors
Think of EUV machines as the Hadron Colliders of the tech world. They’re bus-sized machines with over 100,000 precision parts. Building just one takes months, and it involves firms across continents — including German optics company Zeiss, which creates atomically smooth mirrors for the system.
To produce EUV light, lasers strike molten tin droplets 50,000 times a second, generating an ultra-pure beam. This beam travels in a vacuum chamber — because even air can distort it. A single dust particle can ruin a chip.
That’s how advanced and delicate the process is — yet it’s the only way to etch billions of 2nm or 3nm transistors onto a chip used in AI processors like NVIDIA’s H100 and AMD’s MI300.
Why ChatGPT and Gemini Need ASML
The AI tools millions use today — ChatGPT, Gemini, Grok — all run on power-hungry GPUs and AI accelerators made using sub-5nm process nodes. These nodes are only achievable using EUV.
For example:
| AI Company | Chip Used | Made With EUV? |
|---|---|---|
| OpenAI (ChatGPT) | NVIDIA H100 | ✅ Yes |
| Google (Gemini) | TPU v5 | ✅ Yes |
| Meta (LLaMA) | Custom AI chip | ✅ Yes |
Without ASML’s EUV machines, none of these chips — and therefore, none of these tools — would exist at their current scale and power.

Tech Monopoly and Geopolitical Chess
ASML is now a chokepoint in the global tech supply chain. The U.S. has blocked ASML giant from selling EUV machines to China under export restrictions, fearing advanced chips could aid Chinese military AI development.
In 2023, China began developing its own EUV systems, but experts say it’s years behind, lacking critical lithography expertise and supply chain access.
ASML’s position has placed the Netherlands at the center of U.S.-China tech tensions — despite being a small nation, it controls a technology bigger nations can’t replicate.
Conclusion: ASML Is the Motherboard of the AI Age
If NVIDIA and TSMC are the arms and legs of AI hardware, ASML is the spine. It doesn’t make chips. It makes the machines that make the chips — and without it, our digital world would still be stuck in the 2010s.
Just as Gutenberg’s printing press unlocked the information revolution, ASML’s EUV machines have unlocked the AI revolution. You might not see its name on a chip or in a chatbot, but ASML is the hidden force behind the intelligence we’re rapidly teaching our machines.
