This video is a really cool dive into EUV for the uninitiated (me) https://youtu.be/MiUHjLxm3V0?si=kEPSicC2WXYhcQ6L

The thing I didn't understand after watching that video was why you need such an exotic solution to produce EUV light. We can make lights no problem in the visible spectrum, we can make xray machines easily enough that every doctors office can afford one, what is it specifically about those wavelengths that are so tricky.

It really is the specific wavelength. Higher or lower is easier. But euv has tricky properties which make it feasible for Lithography (although just barely it you have a look at the optics) but hard to produce with high intensities.

The whole “exploding tiny drops of metal” in the middle of this is just Loony Toons. This machine is literally insane and two of the companies I am long-long on would be completely fucked without it.

Yes 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.
But 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.
Oh 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.

Which isn't easy considering they explode tin droplets in the machine. I think that's the point the other commenter wanted to make.

I have shares in one of their biggest customers, and one of their customer’s biggest customers.
We are quickly leaving the realm of dependent variables still looking anything like diversification.

Okay this is weird.
> The key advancements in Monday's disclosure involved doubling the number of tin drops to about 100,000 every second, and shaping them into plasma using two smaller laser bursts, as opposed to today's machines that use a single shaping burst.
This is covered in that video. Did they let him leak their Q1 plans?

So how small are individual components (e.g., transistors) nowadays? Presumably there's a lower limit: once you're a few atoms across, it seems that you can't go any smaller (?).

Gates are about 30-50 nm wide, even though they're called '3nm' for marketing reasons.
phkahleran hour ago
Metal pitch is 26nm. That means parallel wires can be placed 2 wavelengths apart with 13.5nm light.

I still think we should have gone with average gates per square mm as a new yardstick. It would also make sense to the Numbers Go Up people.
itopaloglu8323 minutes ago
It’s going to be quite funny if they can go below 40nm in gate pitch size, because they’ll need to call it 0nm.

> to help retain the Dutch company's edge over emerging U.S. and Chinese rivals
Great news, but what a strange attempt to equate the U.S. and China in this and build a narrative. Cymer was founded in San Diego.
petcat2 hours ago
Yeah it's an interesting angle in the article. The EUV light source technology is completely designed, developed, and manufactured by Cymer in California, which is a US company that ASML acquired in 2013. If export control agreements were not in place then ASML would have never been permitted to acquire Cymer. And if they are not enforced then the US would almost certainly require ASML to sell Cymer back to US ownership, TikTok-style.
The reality is that it's American technology that is used in ASML machines so I don't know why the article tries to frame it like it's a competition.
ahartmetzan hour ago
Which American rival would that be anyway? I have not heard of any.
petcatan hour ago
xLight is the promising new US competitor to Cymer. Lots of funding from the US CHIPS And Science Act. Founded by Dept. of Energy engineers who formerly worked on large-scale X-Ray systems and particle accelerators.

This is a steep increase of power to get out of a vacuum system that is highly sensitive to temperature changes.
