Twice. They have to hit the molten droplet twice.
Once "gently" to deform it briefly into a concave shape, and the second, harder pulse to actually activate the droplet to emit extreme ultraviolet light
Asianometry on EUV. Skip to 10m50s. https://youtu.be/5Ge2RcvDlgw https://youtu.be/5Ge2RcvDlgw
- fennecfoxy 3y agoNot only do they hit it twice, but they're also depositing and hitting it twice _50,000_ times every second! https://www.asml.com/en/technology/lithography-principles/light-and-lasers#:~:text=Then%20a%20more%20powerful%20laser,repeated%2050%2C000%20times%20every%20second https://www.asml.com/en/technology/lithography-principles/li.... Just absolutely insane engineering going on there.
- fnordpiglet 3y agoAnyone who reads these descriptions and doesn’t realize this is literally the magic of sorcerers predicted in our fantasy lore have lost the ability to dream. What an amazing time to be alive.
- dougmwne 3y agoThe process sure, but the end product? Sand awoken, talking, thinking, creating, dreaming. Merlin was not so powerful.
- AshamedCaptain 3y agoI'm quite sure that the people working on this see lots and lots of barely holding duct tape in what you describe as "magic".
- ThrowawayTestr 3y agoAnd yet that duct-taped machine can consistently fire two laser beams at a single droplet of molten tin hundreds of times an hour. Pretty magic if you ask me.
- fnordpiglet 3y agoI teach my daughter science is just magic we understand. Once we understand something it becomes ordinary, but the trick is to hold onto the wonder.
- jacquesm 3y agoI'm quite sure they know the difference between real engineering and pretend engineering and I can guarantee you there is no duct tape in there, each and every last residual effect is part of the model, if it weren't it wouldn't work at all. The scales you're talking about imply that even the tiniest parasitic effect that you could safely ignore otherwise is going to utterly dominate your work if you don't account for it.

- zeristor 3y agoJust so long as Stormtroopers aren’t doing the aiming.
- audunw 3y agoAsianometry is an amazing channel for topic like this. Also check the video on water for chip manufacturing. You’d never think there so many interesting challenges with something so mundane as water. Modern chip manufacturing is basically black magic.
- Hikikomori 3y agoBasically the title of this presentation. https://youtu.be/NGFhc8R_uO4 https://youtu.be/NGFhc8R_uO4
- jacquesm 3y agoHighly recommended if you haven't seen it yet.
- automatic6131 3y ago>Modern chip manufacturing is basically black magic. This, if you ever want to feel wonder at things the human race can accomplish, lithography has to be in the top 3 reasons imo.
