Dont forget quantum physicists

As an ASML employee, I can say that Cymer deserves all the credit for the light source, that's pronounced Sy-Mir. Cymer began development of EUV from a design perspective back in the mid 2000s. The reason ASML bought Cymer is that the two companies required close cooperation to develop an EUV light source/scanner system and this was technically difficult because of responsibilities to keep technology secrets.

When Cymer was in it's infancy I interviewed with them. I'm a medical laser engineer (BSEE). End story was I decided I wanted to stay on the medical end of this technology and am glad I did, but who knows where I'd be if I took them up on their offer?

Wow. I'd heard the phrase 'tin droplets" associated with EUV, but I had no idea they were using one laser pulse to create a convex target for the main pulse. That's absolutely ridiculous.

I has *NO* idea this is what it took to make EUV light for this manufacturing process. It's hard to believe, that out of all the people working on this, that this was the solution they landed on. Truly spectacular engineering and science. (if not straight up bonkers)

Your channel is one of the very few channels that bridges the gap between a good lay understanding of the semiconductor industry and a professional understanding of the semiconductor industry. Its a very rare thing to find in any field. I find it interesting that the "secret" part of "trade secrets" is becoming less and less important as a smaller and smaller number of people or corporations or nations are actually capable of making use of those secrets. I appreciate the explanations that companies like ZEISS give for the construction and function of their optical systems, but on its own it doesn't really increase your understanding of how the whole process works. I get a lot of people in the maker space asking questions like "why can't we 3d print our own microchips". This is why. There's no half-assing an EUV light source. Similarly, there's no half-assing ultra-pure water or the purity and precision of reagents and gasses used in semiconductor manufacture. One microscopic droplet of process oil in a gas stream is enough to ruin a processor, or, worse, ruin a photo-mask. If you're lacking for ideas for videos, one of the things I don't really understand well is how wafers are cut and polished. I'm assuming this has had to keep up with the process nodes as well.

@@eone199 I think people get the impression that Moore's law somehow applies to 3d printing. We've been stuck at (optimistically) 100 microns for 20 years for 3d printing and 10 microns for 2d printing for about the same amount of time. For me I guess its interesting to think of how you could pull off making functional electronics "at home" but you're talking about combining molecular beam epitaxy and electron beam lithography and nanometer scale additive manufacturing (which doesn't exist yet, we're still at the micron scale even in research) and now you need tubomolecular pumps and far beyond reagent grade materials and high end CNC machine tools. So I think you could make your own processor as long as you were willing to invest your life savings in a machine that could produce 1 questionable quality processor per week at a running cost of a thousand dollars a piece. For the record, though, we're sitting at the 5nm node right now (which doesn't mean 5nm at all, but that's another story) and electron beam lithography has been able to produce sub 10nm features in semiconductors since the mid 1990's. A lot of progress has been made in industry and mass production but in terms of the academic research leading it, far less progress has been made than people assume.

Very interesting. I wonder if an approach used by Becton Dickinson around 1980 to steer droplets either is used by ASML, or could be. After forming droplets with a Piezo, the droplets were hit by a laser and optically scanned (diffraction&absorption). The spectral results were instantly analyzed and used to apply a positive, neutral or negative charge to a pair of plates. As the droplet passed between the plates, the charge would then SORT each droplet into one of three vials. This served as an alternate means for concentrating a desired component, when other methods (like variations in density) would not work. The analogy for ASML would be to used the charged plats to steer or align the tin droplets, and perhaps also serve to minimize the travel of tin debris.

@@gregparrott Wow thats super cool! :) What do you think of my theory? Since all parameters in the EUV machine are known or measurable and the random factor of tin contamination has been engineered down to a predictable degree any additional method of levitation would add another complication and thus reduce efficancy of the machine. Now another question that comes to mind now is if the horizontal spacing of the tin droplets should be detected from distance or artificially manipulated by the method of dispension. I think droplet size is controlled by tin dispensing nozzle type+pressure+viscosity+temparature and cavity athmosphere. Since it is a two dimensional line with 5x the droplets of the actual pulse frequency they only expect 20%of droplets to be useful. I guess it its almost trivial to use highspeed cameras because models with multi million fps and very accurate interface that provide a very high line resolution - atleast high enough to determine good droplets, time the first pulse,determine correct tin formation and time the second pulse. I guess the performance increase mentioned in the video will come from expirience "in the field" and subsequent data collection and process optimization.

@@G4m3G3ni3 What you're saying is interesting, but I'm missing some of the details and have to conjure up. We're both assuming that the tin 'droplets' are formed in situ, which implies it is molten when it enters the nozzle. While it likely is molten, it is possible that they're actually small pellets. Assuming it's molten, the Piezo actuators used in fuel injection could be (highly) redesigned for metals. For starters, tin's density is 7.3X that of water, ~10X that of gas and ~9X that of Diesel. As you say, the piezo's characteristics, the size/shape of the nozzle's cavity, and the electrical pulse's shape can influence the resulting droplet. Saying it is a 'two dimensional line' is confusing. By definition, a line is one dimensional, and a plane is two dimensional. Also, I found nothing in the video which suggests "5x the droplets of the actual pulse frequency". At 14:14, he says they're hitting "50,000 bullets a second with a laser, twice (twice because two lasers hit each droplet). He mentioned the droplets are traveling at 80 m/s and are separated by 1.6 mm. If you crunch those numbers, this affirms there are 50,000 droplets per second.

OMG. This is far beyond what I had imagined.

Cyclotrons and synchrotrons are not the same type of accelerator, despite both being "doughnut" shaped -- their principle is not the same: cyclotrons use a time varying magnetic to speed up charged particles by magnetic induction, whereas a synchrotron uses electric fields to speed up particles in linear stretches, and magnetic fields at the "joints" to bend the trajectories -- synchrotrons are not actually circular, but rather they are many-sided polygons. In synchrotrons, the X-rays come out at the vertices that join two linear stretches. In fact, the LHC is a synchrotron, and it also produces X-rays the same as those synchrotrons which are used explicitly for that purpose: the X-rays are a byproduct of how synchrotrons work. The LHC is not simply related to the ones that are used for their X-rays, it is one of them, albeit used for a completely different purpose. And great video, by the way. Despite my minor "complaint", you explain things in a very straightforward fashion. Keep up the good work.

@@Eletronicafgyou're correct. I mixed them up -- been a few decades since I studied them. I should do a bit of refreshing of some accelerator physics.

@@isodoublet yes, you are right, I got the betatron and the synchrotron confused. As for the rest, I was trying to add more information -- the LHC is a synchrotron, but as far as I know, it's not used as an x-ray source. And of course, Asianometry's videos are excellent regardless.

@@gildardorivasvalles6368 Oh, don't get me wrong, I think your post was very informative.

Wow, I didn't know this had been achieved. I remember reading a bit about the promise of Xenon years ago. I was unaware what was going on with tin. I was always interested in mirror making for telescopes. To think that the first pulse creates a curved surface is amazing. Then the second pulse strikes this curved surface squarely to create EUV....WOW! What an incredible accomplishment....

Thank you for sharing this
