Absolute banger. ASML actually sponsored the video too

One of the comments about it is hilarious

China be like : WRITE THAT DOWN!! WRITE THAT DOWN...
Seriously who needs corporate espionage when you got videos like that
DZCreeper@reddit
Doesn't matter how much knowledge they have, being able to produce the mirrors with 50 picometer aka 0.05nm surface finish precision is the bottleneck.
Carl Zeiss is the only company in the world that does it.

So what happens if some religious group or the anti-tech nutjobs blow these guys up? Seems like putting the entire world technology in one company is utterly stupid
Own_Cartographer8962@reddit
Not really. The expertise and equipment used to develop carl Zeiss Starlith mirrors would still be unharmed (eg. Zygo Corporation, CAMECA, Bühler Leybold Optics). It would Probably take three years to rebuild but after that production would resume again.
In order to destroy EUV it would require a large-scale and heavily coordinated effort by a hostile country in the middle of western Europe to destroy every one of ASMLs component providers and there retrospective manufacturing tools.
If this happened, being stuck on 2nm would be the least of our issues.
Strazdas1@reddit
would you say a hostile country buying up critical infrastructure in western europe make this plan easier?
puffz0r@reddit
what are you referencing?
Strazdas1@reddit
A hypothetical.
Strazdas1@reddit
In this unrealistic scenario it would simply mean that the production of new machines would stop for a bit until the mirror manufacturing is rebuilt.
StickiStickman@reddit
How would you even make a surface finish smaller than an atom?
Strazdas1@reddit
probably by arranging atom structure in a shape that makes the surface smooth on atom level?
DZCreeper@reddit
Far outside my area of expertise, but I know atoms have different sizes. Increasing the proton count shrinks the atom because the electron attraction increases. Increasing the number of electron shells will expand the atom.
Apparently you can then manipulate electron orientation by doing metal deposition at extremely low temperatures.

China is pouring obscene amounts of money into figuring out EUV, they've already (kinda) figured out DUV.
If you think anything in this videos is news to them then idk what to tell you.
No_Hornet_1227@reddit
The increasingly incoherent US response (see: CHIPS Act) is essentially "well fuck, they're catching up and we can't stop them, what do we do"
They could ban nvidia, amd and intel from selling gpus to china, hong kong and singapore for starters... and any country that tries to help them do gpu smuggling... and if jensen doesnt understand he could be go to prison for being a traitor.
nanonan@reddit
That won't slow down their advancement in fabs, if anything it is doing the opposite. They already have banned those companies from selling certain categories of products. The only result of that banning has been Chinas acceleration of its plans.

go get some fresh are and get your house checked for carbon monoxide
ComatoseSnake@reddit
Ahahahahahah he thinks a superpower doesn't already know entry level information like this pahahaha
Berengal@reddit
Asianometry already has several videos about EUV lithography and the difficulties of making it viable/scaleable.
BuchMaister@reddit
Nothing there is out of public domain knowledge. Working principles, doesn't get you anywhere without the intricate design, know how and manufacturing capabilities of the sub components and assemblies (for example manufacturing the lenses is very difficult due to their tolerances).
Eremita_Urbano_1655@reddit
Generating UV light by creating plasma with a laser in a droplet of tin is crazy.
lucidludic@reddit
I haven’t watched this video yet, but my understanding is that they strike each droplet twice with a laser. First to get it in the correct shape and then to generate the EUV light.
Earthborn92@reddit
This is correct.
ReipasTietokonePoju@reddit
300 000 dollars for single mask ?!
So, 80 layers = 80 masks = 24 million dollars ?
Shaq_Attack_32@reddit
not every layer will use EUV. DUV is just fine for many of the masks.
Earthborn92@reddit
That's one stepping. You'd need more masks if you need to make changes or if the mask has a defect.

Imma go for some proton beam lithography
