Is this just restating the size of the same shipment three times?
The more straightforward video of ASML EUV is from Branch Education: https://www.youtube.com/watch?v=B2482h_TNwg
Because that vid gives an overview of the whole machine, it gives context to what each scientist is talking about in the Veritasium interviews.
Makes one wonder: Would we be much better off of worse off if we reshaped society to do more of things, where a new technology is unlikely to work but highly beneficial in the limits? Would we sooner have 10 additional ASMLs or waste a lot of resources?
What is no longer mentioned is that ASML made another big gamble at the time they started on EUV. They decided to make an all-in-one chip making machine that took silicon and output chips (instead of matrices of chip circuits laid out on a wafer).
On paper, the machine would save a lot of money for the fab houses. IRL: no one asked for it, and no one was willing to risk their entire production on a single, untried, swiss army knife of a fabricator.
The whole program was a wash. People were reassigned and the project died a very quick death. ASML lost a ton of money on this misguided attempt, but not enough to choke them.
So, they rolled the dice twice, and one gamble paid off handsomely. If it went the other way, they'd be a smaller company, and Moore's Law would be overshooting reality. If neither paid off, they'd be DOA.
In this case, its the latter.
As a software engineer by trade, the above parable communicates to me two very important things and little else by comparison: that the machines are ultimately fragile and nowhere near "optimised", since the complexity is by own admission substantial to put it mildly; the machine is not a commodity, exactly, one of the million pieces breaking subtly likely renders it inoperable; its cost is proportional to its complexity (read: astronomic); by mere fact it's a focal point of geopolitics only supports the rest of the argument it's a machine of current stone age much like siege engines were at some point the closely guarded secret win-or-lose multiplers of feudal culture.
I mean it's certainly interesting to read about the complexity, but reducing the complexity and commoditising the whole thing is what's really going to be impressive I think :-)
I am probably speaking out against the nerd in us, and none of what I said should detract from enjoying the article or the subject, it's just that I think complexity here is the giveaway of us not having conquered UVL exactly, not quite yet :-) Or maybe we lack the right materials which would allow us to reduce the machine or make it less complex or prone to calibration related errors.
What is the corresponding revolution in chip production? I imagine something like FPGAs for litography - a wafer that can somehow work on another wafer in a sandwich-like configuration. Such a process could potentially improve on each iteration and thus get very good, very fast.
Either China will catch up on this or that particular technology will become obsolete. But it is certain that they won't stay behind forever (measured in a small number of decades at most).
whatever many secrets are involved, information wants to be free and it's hard to believe that others won't figure it out.
by the time they do catch up we better be steps ahead. what's after EUV?
- ASML's High-NA EUV machines ready for high-volume production
- Machines have processed 500,000 wafers, showing technical readiness
- Full integration into manufacturing expected in 2-3 years, ASML's CTO says
After that, it may be X-rays.
A disruptive step would be to move to 3D printing, but that (among other issues) is too slow at the moment. Maybe, ideas from nano robotics (https://en.wikipedia.org/wiki/Nanorobotics) can help there.
The lithography equivalents of that are laser direct write lithography and e-beam lithography. They've been used for decades in research labs, but they're impossibly slow for any mass production.
Atomic Semi are trying to make some derivative of these processes happen at a commercial scale.
I can understand why you can't just take one apart and copy it.
There's (apparently) 4 decades of accumulated cutting edge scientific research that has gone into these machines.
I suspect the machinery, process and human expertise required to simply produce the parts required for these machines is the real moat (oh and I guess the US-led export controls too).
The build tolerances for components are incredible. There are 11 primary mirrors in an EUV machine, each one has something like 100 coats of ultra-pure materials that are precisely deposited in picometer-thick layers with tolerances in the nanometers, across a 1-meter wide curved surface.
Then you have to position the mirrors perfectly inside the machine, again with tolerances in the nanometers.
So even if you know what you need to do, having the equipment and expertise to do it is a different thing.
And that's just one part of the 100,000+ parts that make up an EUV machine.
But in this case the Chinese will just develop their own alternative, that might work as good or even better
I mean we're not talking AMD FX and Core 2 Duo here, it's Raptor Lake and Zen 3, it's perfectly viable and still being sold in droves right now.
There’s also the issue of older process nodes not being profitable enough anymore, which explaines why at the height of the chip supply crunch older ARM chips were in short supply but there was ample stock of the 20nm feature-sized RP2040.
I don't think I'm being entirely hyperbolic when I say the consumer market only exists to put devices that can connect to and feed the datacenter loads into the general populations hands.
Yes and no. If just formally calculate, yes, servers are small market volumes. But, they are much less constrained financially, than private person, so from same fab one could earn much more money if sell to server market, than if sell to consumer market.
Plus, space arrange could last years.
Heat dissipation in range of megawatts could be just prohibited by local regulations.
So, space in large cities is very serious problem, and for business it is usually easier to "compress" as much computing power as possible in one rack.
Also big problem - connectivity - you cannot place DC where it cannot be connected to power grid and to very powerful network.
So yes, DC floor space is severely limited.
And the third issue - last decades, rack servers dissipate extremely large amounts of heat, I hear numbers up to tens Kilowatts per rack, which is just hard to dissipate with air cooling (as example, all IBM Power servers have option of liquid cooling, but this is totally different price range).
Surely you don't believe that the entire chip industry had not thought of "wait what if we just make the chips bigger".
