Maybe also quencher for secondary emissions.
EDIT: See attached. Vanadium oxide might offer several beneficial characteristics including the two we just speculated on.

I have to read this entire article up, but Dylan Patel seems really impressed by the network setup that Deepseek did to improve latency and such.
Just because the US government says that NVIDIA isn't allow to sale their most advanced AI chips to China doesn't mean that China won't be able to get their hands on those chips. Its a widely produced and commercially available product and China has both the contacts and the money to buy them from third parties aka the black market. China of course will have to pay a premium on those chips but for China's AI efforts its well worth it.
What attached?
It is a matter of degrees of separation.
1) You can sanction China in the 1st degree.
2) So Chinese firms buy from re-sellers in Japan in the 2nd degree.
3) If a local governments allied to US like Japan cracks down then Japanese re-sellers can sell to Thailand who then sell to China in the 3rd degree of separation.
Now the 2nd degree of separation doesn't include only Japan but many nations. And then even more nations in the third degree when re-sellers radiate to avoid local bans. Pretty soon you'll have to involve the whole world to keep these chips from reaching China at which point you'll probably wreck Nvidia's international business.
Under US law, if enforced to the fullest Nvidia theoritically needs to not only check who they sell to but also who their customers sell to and so on and so forth down the rabbit hole.
At some point, you'll just need to develop a blind eye if you want to sell globally.
And we haven't gotten into gray areas where people smuggle directly to China to profit from cutting out middle men in the 2nd and 3rd degrees of separations or simply buying currently unbanned devices that contain Nvidia chips.

They can’t even stop North Korea from getting American chips but somehow they can stop China? That’s why the decision makers are clueless.
Gray market imports. Russia is doing the same thing.
They cannot easily stop such imports when these products are so commonly available.
The only way to stop it would be to require strict export licenses on a per customer basis like they used to do with Cray computers back in the Cold War. But this would make those chips a boutique product and possibly uneconomical to develop.

Adding administrative costs and friction and making large-scale purchases/projects off limits (large data centers made from smuggled parts is highly inefficient and of course, no way Nvidia can give technical assistance for it) or prohibitively difficult is part of the intent. Resources are not infinite
Sorry. Looks like the screenshot I wanted to throw in was too big lol. But here’s the paper I was trying to excerpt from. Somewhere in there it discusses some potential benefits of using
While trying to find the paper again also stumbled on this one that I think is a good overview for some of the chemistries involved in potential EUV photoresists.
Very interesting.
However, this study does not go into EUV wavelengths and it is still questionable as to the interaction with Sn.
I've searched a whole bunch for V oxide and tin with EUV, and can't find much other literature.
