You forgot WITH LASERS, and IN A VACUUM
replyThe old SemiAccurate article https://semiaccurate.com/2013/02/13/euv-moves-forward-two-st... was very funny.
replyIIRC from the Veritasium video[0] there is actually some hydrogen gas flowing at quite a high speed though the laser chamber to carry away the tin debris so that it does not accumulate on the mirrors.
replyYes it was crazy when I first heard about it "wait what? they shoot it in mid-air?" and that was before I found out they did that like 30k times a second.
replyBut now 100k times a second apparently. Humans are amazing.
You have a machine that’s basically a clean room inside and one of the parts is essentially electrosputtering tin but then throwing all the tin away and using the EM pulse from the sputter to do work.
replyOh and can you build it so it can run hundreds or thousands of hours before being cleaned? Thanks byyyyyyyyeeeeee!
The inside of those machines are far, far cleaner than the inside of any clean room ever entered by a human. They have to be molecularly clean.
replyWhich isn't easy considering they explode tin droplets in the machine. I think that's the point the other commenter wanted to make.
replyThink about the purity requirements that places on the tin.

reply< Why?!

< Yes, of course you are.
> 100,000 times per second.
< [AFK, buying shares.]
Don't forget that they are hitting each droplet 3 times.
replyI have shares in one of their biggest customers, and one of their customer’s biggest customers.
replyWe are quickly leaving the realm of dependent variables still looking anything like diversification.

replyWhat does that mean?
