> retaliate by withholding ASML’s tech

The problem is that the core technology that makes ASML's tech valuable is the EUV light source which is entirely designed, developed, and manufactured by Cymer in California, which is a US company that ASML acquired in 2013. That acquisition was permitted only under strict technology sharing and export-control agreements.

I have no doubt that this administration would forcefully "take back" Cymer if the EU tried to restrict access to ASML lithography machines. They would force a sale back to US ownership, TikTok-style.

This framing gets the supply chain backwards. Cymer makes the source vessel, the part that generates tin droplets and converts them to plasma. But the laser that actually powers that process is a 17-ton, 40kW CO2 beast with 457,000 parts, built exclusively by TRUMPF in Germany. And the optics, mirrors smooth to tens of picometers that literally no one else on Earth can make, come from Carl Zeiss, also German, organized as a foundation that no foreign government can force into a sale. ASML only manufactures about 15% of an EUV machine's components. The rest comes from roughly 1200 suppliers concentrated in Germany and the Netherlands. Seizing Cymer gets you one subsystem with no laser to drive it and no optics to focus it.

The real problem with this theory is that EUV isn't a product with a capturable bottleneck. It's more like a standing wave of institutional knowledge distributed across organizations that have been co-developing at picometer tolerances for 30 years. TRUMPF's leadership described the arrangement as a "virtually merged company" with open books across all three firms. That kind of integration knowledge doesn't transfer via acquisition. China has been throwing enormous resources at this with access to published research and former ASML engineers, and their prototype still isn’t expected to produce working chips until 2028-2030. Saying the US could grab Cymer and start producing EUV machines is like seizing a transmission plant and calling yourself a car manufacturer.

Yes, we all know that ASML is a multi-national effort, with critical technology components provided by several countries. The point is that the EUV light source is one of the critical technology components and it has not been replicated anywhere else (so far, see xLight founded by Dept. of Energy engineers and funded by the US gov).

It's a bargaining chip that this administration will undoubtedly use to make sure that US access to ASML lithography machines remains undisturbed.

[joe_mamba]

You're missing the point. Nobody will take back anything since that hurts everyone, but if the US wanted they could license EUV tech to Nikon or Canon and give ASML a huge PITA of refreshed competition.

Similar to TRUMPF lasers and Zeiss optics, other companies from US and Japan like Coherent and Canon could have a crack at replicating the laser and mirrors given enough IP and resources if the US really wanted to decouple from ASML, since they're still man made objects, not magic things given by gods.

US is the richest country in the world and the second biggest manufacturer after China. Do you think the country that built the SR-72 and other sci-fi shit wouldn't be able to make a EUV lithography machine in house if they were to treat it like a Manhattan project instead of a side hustle?

this exact same logic applies the other way, though... unless Cymer is selling magic objects given by gods?

>Do you think the country that built the SR-72 and other sci-fi shit wouldn't be able to make a EUV lithography machine in house if they were to treat it like a Manhattan project instead of a side hustle?

do you think that ASML (or TRUMPF or whatever non-US entity) would be unable to make the EUV light source in house if they were to treat it like a Manhattan project instead of a side hustle?

[joe_mamba]

I agree with you, but that was my point exactly. No party holds all the cards to dictate the rules of the game like people bullish on ASML thought that they're somehow untouchable. They're untouchable because the US allows them to be because they play ball with the US admin and push back against rules they don't like from the Dutch government.

It's a gentlemen's agreement that will be held together by mutually assured destruction if one party tries to decouple completely.

The general decoupling from US tech you see has started after the general enshitification of major IT services from FFANG, not exclusively due to Trump, and not exclusively to US, Spotify is also seeing a lot of backlash.

>do you think that ASML (or TRUMPF or whatever non-US entity) would be unable to make the EUV light source in house if they were to treat it like a Manhattan project instead of a side hustle?

The EU(Germany, Spain and France) can't unite to build a next gen fighter jet together, can't decide how to tackle illegal mass migration, can't decide a sane energy policy that isn't hypocritical or anti-industry, or on a single direction on defeating Russia. A EUV Manhattan project is the least of their issues right now which moves the balance of power in the US court for the moment until EU members figure out how to work together.

> can't decide how to tackle illegal mass migration

the mass migration caused by american wars in the middle east you mean? Also, frontex seems to be working fine so far.

>on a single direction on defeating Russia

unlike the US, which has stopped all military aid to ukraine in 2025, and seems to be favouring russia more and more.

Lets not forget, europe is increasing its military en masse mainly because on one hand you have the russian flattening ukraine, and on other hand you have the US demanding greenland.

Who needs further enemies with friends like this?

>the mass migration caused by american wars in the middle east you mean?

Nobody forced the EU to open its borders. It's their job to defend their borders from intruders, foreign especially military aged males with no visa, instead of acting as a global charity with their taxpayers' money then wonder why the far right is booming and arrest them for hate speech.

>unlike the US, which has stopped all military aid to ukraine in 2025

This is news to me that doesn't math what Google returns. Care to back that up?

>and on other hand you have the US demanding greenland

That's bad indeed on the US, but EU can't even defend Ukraine from Russia, a broke-ass country, do you think they would have gone to war with the US over Greenland? The US can do this because the EE can't do anything.
