I think the silicon industry is the equivalent of the modern space race. It just goes to show what insane advancements science can make with collaboration and a good amount of financial incentive behind it. It never ceases to amaze me how much further we can push this single element and I'm curious what will lie beyond the silicon lands.

[@alexanderbelov6892]

​@@mindnova7850Doing so much with so much less is all about diminishing returns. The most influence on performance give parallel instruction execution that has hard limits due to data and control path dependencies in the programs. While core performance is no better than frequency multiplied by IPC. Frequency does not grow well. 2000 year CPUs had x5 less frequency than now. So the most performance gain had to cone from IPC grow. Was it at least x4 or worse since 2000 year?

Interesting comment about using computers to make computers faster. In 1978 my first job was making circuit boards for Motorola 6802 based industrial computer. It controlled a retrofit to a K&S 478 wirebonder making it automatic by targeting 2 points on the die and pushing the button. We had no drill for to make the PCBs so we took the computer we made and bolted on so big stepper motors and turned the wirebonder into a drill for the circuit boards. A vacuum cleaner was the dust collector. Our customers when the toured the factory would stop at this homemade hack of a machine, and ponder. Many commented "wow, the machine is making itself!" Indeed....

[@kubetail12]

Mathematically, a lot of these computations are numerical inversions. OPC could be considered a crude numerical inversion depending on how it's done exactly. Typically, you have inputs and a mathematical model that gives an output. In an inversion, you know the output, but either the input or model is unknown. If the initial paper used simulated annealing, the computations most likely minimize the L2 norm, which is a classical numerical inversion technique. I imagine they have been predominately using Bayesian inversion in ILT. That gets very computationally intensive when you add complexity to Bayesian Inversion, but it is more flexible, and uncertainty quantification is given because the method involves probability distributions. I don't know what CuLitho uses, and it's hard to verify on the internet. I was thinking of AI Inference because NVIDIA has been using ML in GPU design recently. There are so many inverse problems in science. If it's a remote measurement or you are trying to determine the interior of an object from an exterior measurement, then it's most likely an inverse problem.

[@simaesthesia]

I appreciated your closing philosophical statement about using computers to design chips to make faster computers. It reminded me of the old "if you could make a machine that replicates itself but half the size, and the resulting machine does the same, how far could that recursion progress until the resulting machine is too small to work?"

I was taking a VLSI course back in the early 80's, and for a class project had to write and use a LISP design rule checker. At work the lab next to me had a DEC minicomputer. I asked for several seconds of CPU time to verify my chip design. It actually took several hours of CPU time. Not exactly lithography, just a lesson about how much computational power is required to design even a VLSI sized chip.

[@gorak9000]

Or perhaps your algorithm just wasn't very efficient? :) Funny that in the 80's taking a VLSI course meant writing your own DRC. When I took it (~2008) it was doing full custom transistor layouts, schematic capture, and a lot of timing analysis and spice simulations. Also measuring (in simulation) static and dynamic power consumption. Seeing as the cad tools haven't changed much since then (at least at the level of what's used in an intro class), I doubt it's changed much since I took it.

It's worth mentioning that this will not have any kind of major impact on the actual throughput of the production of the wafers. There were some channels that saw this Nvidia breakthrough news and got carried away with the idea that throughput would be 10X faster or whatever. This will help speed up design, the throughput is still the same.

[@RK-fr4qf]

Amazing work as always, sir!

[@douginorlando6260]

This is how I make sense of it. The fact that a photon is emitted from an individual atom implies the theoretical resolution limit of masks could reach the size of an individual atom regardless of the wavelength. (This assumes the etendue of the light source is the size of an individual atom). Working backwards, the photon wavefront emanating from the source atom must be duplicated at the absorbing atom. This is essentially what the mask design is trying to do. It’s more like a hologram than a stencil image being focused on the wafer. The wavefront reaching a point on the wafer must reach that point in phase from as large a solid angle as possible.

Reminds me of the technique used for inter-chip communication on computer motherboards. Basically two chips "ping" each other and "learn" how to distort their own output so the receiving end gets the cleanest signal possible. -> Introduce distortions at the source so they overlap/interfere among themselves over the conductors path so the received signal is clean. It was probably Intel who developed this technique but I cant remember its name...

[@wombatdk]

Fascinating presentation and topic. A fair bit is beyond my understanding, but it gave me a glimpse into the science of chip making. Very cool indeed.

[@ashleyobrien4937]

Immersion lithography is exactly the same concept that is used with light microscopes, when wanting to take a look at a sample of whatever under the highest magnification possible with light microscopes, it is common practice to place a small droplet of a very specific kind of oil, with a very specific refractive index, the light travels from the light source, underneath the sample, through the prepared sample on a glass slide with a thin cover slip of glass, the oil droplet contact both the top surface of the cover slip and also makes contact with the magnifying lens, the oil is carefully chosen so that the light rays basically pass right through the oil/glass interfaces without being wildly refracted, it's basically a clever way to collect and collimate limited light to provide more effective resolution at very high magnification, high for light microscopes at least.

[@mekafinchi]

I feel a bit sad for Luminescent Technologies. Coming up with revolutionary idea 2 decades too early. Also I'm worried that it might cement NVIDIA's monopoly in some segments of GPU use (in this case I assume it's something like HPC). I really hope that not only Radeon Technologies, but also a lot of 3rd party companies are working on their own patents. And when it comes to RTG there is always a chance (given their record) that they will make it open source. Because unless CuLITHO (Or however NVIDIA spells it) is not monetized or restrictive in use (so proprietary with control over who can use it for what), then again, it might end up with monopoly. Then again - credit where credit is due - they have amazing researchers. And they deserve a praise (and raise).

I don't know that this sort of complacency is a good way to go about things, it usually doesn't end well.

The thing is you just need one of each picture, 4 16 125, 2^2, 4^2, 5^3, thats not alot of pictures. Once you have the set of pictures, you must replicate the set of pictures. This way uses heavy radiation, or slow etching. Slow radiation has more spin charge, but goes a shorter distance. Like riding the motorcycle through the bee hive into the oblivion. Once a large amount of sets are produced, its taken to the stadium with the 215 ft curved reynolds wrap is gently glowin at 100 billion degrees. The aztec foot bed of graphite with the piano safety lights allows the workers to set the fuzed quartz down.

[@BlindintheDark]

I wonder what the optimizations would look like if you were to allow it to calculate in three dimensions 🤔 if the light isbeing focused down then seems to imply that it's coming into the design pattern from a spectrum of angles? So what if you printed a design image with a few layers? Could you account for the angle difference caused by the focusing to produce an anti-lensing effect, using kind of a shadow box design? Very interesting that these idealized patterns have kind of a morié a to them.

[@seahyx120]

It's most likely to account for the effects of diffraction, that's why you get these kind of morie patterns. This is just my conjecture, but the principle of the fresnel zone plates might be coming into play here, where the mask itself is acting as a lens to focus light into the exact shape you want. Though disclaimer, I'm not an expert on this topic at all. Huygen Optics (the channel) has a really good video on this effect.

[@deniskhafizov6827]

11:07 So this ILT is basically a hologram containing the desired image? Or a process of calculating such hologram?

But surely, there are many common blocks used in a design, so their masks that can simply be called up from a library and used without extra computation ?

Thank you for a fascinating video, I'd love more detail on the techniques , if they could be explained as clearly as you have managed here !

[@weserck6900]

What you suggest was somewhat true when OPC was first introduced. If the distortion was caused only by the immediately adjacent features within the library cell (or block), then the appropriate OPC within each cell could be predetermined and replicated for each instance. But as feature sizes and separations continued to shrink for each generation, the "area of optical influence" continued to increase so that features of adjacent cells (and blocks) would affect each other. What you suggest is certainly true for memory products (which are highly repetitive) and is surely used by memory cell designers.

I feels like some of this computation could be "cached" as reusable features. Additionally, simple proximity rules could probably be established for adjusting the ILT boundaries on a feature.

Manhattan Layout predates VLSI. It originally referred to generic component layout on a PCB.

[@lucasrem]

Steiner points locations, the algorithm used male these CPU design, emulating it to test it before you produce chips. PCB? what did you meant ?

[@weserck6900]

PCB refers to Printed Circuit Board @@lucasrem

ngl i forgot what was that topic of the video around the end lol

12:56 One day we'll have in space fabs for chips. These will use lithography, but with a mask that is several hundreds of meters in size. The light will go through lenses similar in size to that of the mask, but these lenses will be fluid tension based, like almost completely self correcting. Spin fluid in space, and you get a lens, basically. Transistors operating on microvolts, 50 atoms wide circuitry. Makes Ryzen 9 appear like dinosaur bones when it comes to computational effectiveness.

[@alexanderbelov6892]

50 atoms wide wires were already in use. 7 atoms have 1nm size. 50 atoms have 7nm size. This is what 7nm process is capable to print on Si. Now 3mm is in use that allows 20 atoms width wires.

I'm 32 and I would give my soul and sanity to go to school in electrical engineering just to participate as an underpaid intern in this industry. Photolithography is the most extreme manufacturing possible. How does Asianometry seem to know everything about the history, concepts, science, and terminology in the semiconductor industry? He sounds so young to know the equivalent of a veteran in the industry. Mindblowing.

12:00 Manhattan geometry shapes are made of rectangles, not triangles

[@Flynn217something]

We use the GPU to build the GPU.

[@crf80fdarkdays]

That's how lathes are made, but someone had to build the first one from scratch pretty much 🤪

[@sweet_cherry_blossoms]

Can you provide some link where the luminescent technology has been split into synopsys and KLA ? I see it's acquired by KLA. But no reference to synopsys at all.

[@weserck6900]

I can't answer your question directly, but KLA is basically and inspection company (for masks and wafers) and Synopsis is an electronic design automation (EDA) company. Both companies need this software, as do their customers, circuit designers, mask shops, and wafer fabs. I'm sure KLA licenses this ILT software to all parties.

Oopse, maybe I needed to start with the nice guy you mention at the beginning who makes simple videos. I got lost pretty quickly this time.

[@Philfluffer]

Since quantum mechanics is now screwing up lithography (essentially the Universal Laws are now dictating how much further we can take lithography) there’s nothing left to do but add cores, and adding cores is something Nvidia is very good at. Now we need to recode most software to use multiple cores at once (parallel computing) but that’s difficult to do without getting race conditions (having variables getting modified by one core while another core still needs that variable with the previous value but hasn’t yet reached the point where it’s using it). This is all very doable when applying a transformation to graphics but less easy to do in conventional software.

Most power usage in modern devices is simply data transfer. As compute performance goes up it becomes increasingly difficult to feed the compute with enough data to even process

[@alexmcmahon2810]

It might not surprise you that the field of mathematics/mathematical logic concerned with computation is called 'Recursion Theory'. Self-reference is at the foundation of computation in the most abstract and concrete sense. Unsurprisingly, it appears all over the world of computers and the associated engineering of them!

Into the light, I command thee demon chips! On a serious note though, pretty good engineering! Funneling spectrum of light into existence.
