Or this presentation which came out way long ago.
lol
So much more fun than LEDs.
But now 100k times a second apparently. Humans are amazing.
The source in the ASML machine produces something like 300-500W of light. With an Xray tube this would then require an electron beam with 50 MW of power. When focused into a microscopic dot on the target this would not work for any duration of time. Even if it did, the cooling and getting rid of unwanted wavelengths would have been very difficult.
A light bulb does not work because it is not hot enough. I suppose some kind of RF driven plasma could be hot enough, but considering that the source needs to be microscopic in size for focusing reasons, it is not clear how one could focus the RF energy on it without also ruining the hardware.
So, they use a microscopic plasma discharge which is heated by the focused laser. It "only" requires a few hundred kilowatts of electricity to power and cool the source itself.
Asianometry has lots of videos on ASML, this one is specifically about the light sources.
PSA: the si (along with pp) parameter is used for tracking purposes:
?si=kEPSicC2WXYhcQ6L
> 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?
+1 for this video, and the Branch education one. Well done to both teams.
> "We see a reasonably clear path toward 1,500 watts, and no fundamental reason why we couldn't get to 2,000 watts."
Right now the only way to make "bright" EUV (100-200 watts) is to spray fine drops of a metal in a stream, then target and blast each drop with a laser.
pretty wild way to make light.

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.
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.
So the ASML machines combine technologies developed in various places, not only in USA, even if the UV source is indeed a critical component. While an ASML machine would not work without the UV source, it would also not work without many other critical optical and mechanical components.
If it were so easy to make a lithography machine when you have a UV source, Cymer would have remained an independent company or it would have been bought by a US company. Cymer has been bought by their only customer.
The same happens when you look at a PC, it is likely that it contains something essential that comes from USA, i.e. the CPU logic may be designed by AMD, but the manufacturing technology is designed in Taiwan, the memories may be designed and made in Korea, other chips may be designed and made in Taiwan, other components come from Japan, the PCB may have been designed in Taiwan, but actually made in China, and so on.
So yes, it has some important US technology in it, but there is a very long way from a CPU logic design to a physical computer and most of that rarely has anything to do with USA.
The same happens with an ASML machine.
It's crazy that Europeans keep citing ASML as a strong example of European innovation.
LSTC will contribute research (for 1nm) though it isn't clear if it'll be in partnership with ASML or as competition.

with more on the horizon:

I can highly recommend this to everybody who is "somehow in tech or IT"
It's impressive to see that there still was so much room left to improve EUV, but I can't help but be royally pissed off that it will be a looooong time before we the people see any practical benefit of it.
This delay is presumably caused by both the lack of production capacity at TSMC, which is busy with AI, and by the fear that any launch of a new CPU would be crippled by the impossibility to buy DRAM and SSDs for new computers.
