These are just some of the questions i've been pondering for a while.

Because in Cassegrain optics, or in a Schmidt-Cassegrain telescope, the final light path needs to pass through the centre of primary mirror with a curved secondary mirror. The improved image resolution over Newtonian mirror optics is a real improvement though. Unfortunately, unlike the Newtonian telescope, you probably don't have the finesse to grind the secondary mirror to the required grade.

Incredible presentation. I learned so much. Wow.

Nice info , thanks for the detailed explanation , now i can make my NA EUV machine by myself at my backyard

Thanks for the deep dive.

The holes in the mirrors actually reduce transmission in and of itself. But it allows the incident rays to hit within the narrow allowed angles of the multi-layered mirrors, avoiding an even worse loss. Result is increased transmission compared to what a laterally-offset mirror arrangement (as previous machine had) would provide, given the increased NA. It may have a compactness benefit as well.

Excellent and sophisticated presentation! NA is not free. The economics scales by non-linear functions that are pretty complicated, so the cost of optics increase between the square (for processed mirror area) and the cube (for material to support mechanical rigidity). You need to recover that cost by the speed up in throughput. It’s a difficult challenge.

very few layers at TSMC. Intel's Meteor Lake (Intel 4 and Intel 3) will be using EUV on ALL Layers... TSMC 5nm is just a half node from their 10nm process which they call "7nm". Intel will get all the High NA machines. TSMC can't get 3nm working because they are still on copper.

At the FAB I work at production is at the limit with meteorology of anything with a target value below 10nm, even with +/-3nm tolerance.

Most of your videos had covered existing state of art technologies so is great to have one on up coming technologies like advanced EUV technology. It would be great to have a video comparing performance of various nodes and from different vendors. Given that fabs are obfuscating the definition of geometry size (ie Intel 10nm is equivalent to TSMC 7nm) it would be good to understand the true dimensional size and how each technology scale in size/power/performance especially into the 5/3/2 nm nomenclature.

node specs has been getting more and more complex as before we moved to finfets, the transistors were completely planar, so it was easier to define what your "resolution" was and thus your density, with finfets adding a vertical component things got more complicated, we are now adding cobalt interconnects, gate all around soon, imo density is the only metric that still holds up. Then there is the problem of libraries used, they usually advertise the numbers of the dense lower power libraries but cpus rarely use those (amd was able to nearly double the density of their cache in the same node just by changing libraries (talking about normal zen 3 vs zen3 3d's cache die)), To make matters worse at least from what i have seen intel has mostly stopped to share their more detailed node specs with the public, the latest i can find is for the first 10nm that was barely usable.

Outstanding analysis, a remaining curiosity, what is the total cost of ownership for the ASML EUV systems. 150MM or 300MM, this is just the start on a 4 or 6 year investment. Your video does raise a further question, past videos implied ASML is producing 50-60 of these complex machines/ year, with the additional level of complexity, can ASML still produce at that volume?

Really good video! Technical inaccuracies are minor, judged by someone from the industry.

If you think about what has to be *around* the M5/M6 mirror system, the diagram makes more sense. M6 is focusing light onto the wafer, so the wafer must be down right below M5. Similarly, M5 reflects light from M4 and mask up on M6... so the mask and the rest of the projection system must be above M6. Mirrors with holes in them is a pretty standard trick in astronomy!

So... They wanted to make EUV "better and faster", so they increased the NA from 0.33 to 0.55, but that makes two light cones overlap by 1° which is not allowed (for some reason), so they doubled the magnification in one dimension which translates to half the wafer coverage. It seems like there *has to be* a better way of shaving off that 1° discrepancy than reducing the wafer coverage by half! Can't they target a slightly smaller NA or just place a constraint on the mask that says "this tiny sliver of the mask has to be black, so you lose x% of your wafer and mask, but the machine goes twice as fast". I don't know. This is crazy tech...

They are doing weird things to the light source to get the highest contrast possible and this puts a lot of constraints in the optics geometry. There is just no other way. The main constraint is the intensity of the source itself. Brighter source allows faster exposure. But the intensity is already fix because of how the EUV is generated so they have to resort to optics jujitsu.

@@kazedcat medieval alchemists would look at this light show and burn you at the stake. This is good progress even if it uses hacks and slows down wafers per hour. Going smaller undoubtedly wont be peaches but those praise the sun wizards at optics labs are chanting spells alright.

It's rather clumsy isn't it?

@@kazedcat If I'm not mistaken, the light source comes from Cymer in San Diego (acquired by ASML) - and so, presumably, one needs to look for information from them. I once had it described to me as high-energy lasers hitting a molten drop of tin - which produces 13.5 nm 'light.' Not light that any of us can see. Electromagnetic radiation. Wonder if Cymer has a relevant youtube video? kzread.info/dash/bejne/Z62Io7Sak6XeeKw.html

Well the "two light cones overlap by 1°" means the the next mirrors (before and after the mask) would have to physically overlap. That's not possible - you can't have two things in the same place. Jon's graphics here is not accurate, he should draw actually overlapping cones instead of keeping the same cone and just putting the word "overlap" there.

Hi, great video. i work for ASML on the nxe exe

One thing that offsets the lower throughput in wafers is the smaller die. So, as far as actual chip production it probably offsets. Going from TSMC N7 to N3 is about a 3X increase in transistor density. While that won't = 3X the number of die per wafer, it's probably something closer to 2.5X which is still excellent.

I wonder if the stakeholders have already decided what optical node to go next after EUV? Asianometry, please keep us posted on that! I’d love to hear what will be the next crazy odyssey after EUV. Or if they’ll discard that and go for something other than light entirely!

Thanks!

iirc anamorphic lenses compress/decompress to standard sized /film/ rather than screens. Apart from that, amazing stuff! Many thanks!

Works both ways, you use an ana lens to capture a compressed image onto the film and then another ana lens on the projector to decompress it onto the screen

Many thanks INSANE TECHNOLOGIES
