Yes look into jobs in for example the US. They are building lots of new fabs here in the news recently, I can only imagine people with your knowledge is highly sought after. Doesn't hurt to apply and look into.

Hey I just wanted to tell you how much I enjoy and am informed by your videos - love your choice of topics, sometimes quirky (Venera Program), sometimes highly topical (Hardware for AI) but always insightful. Your level of engagement with the physics and math hits just right for me. Congratulations and best wishes for a prosperous 2023!
I became a grad student at UC Berkeley's EECS department in the Fall of 1984. Following my undergraduate degree in electrical engineering and med school, I wanted to know more about semiconductor device physics. I prepared for prelim exams with an undergrad course taught by professor Chenming Hu. He was a superb teacher and communicator. I subsequently learned he is also a superb human being. Professor Hu, if you are out there, this humble medical device scientist is great full for your teaching and the gift of putting to use the FinFET electronics to better manage heart diseases. God speed, professor.
Small correction: I was at a factory making military devices containing 3-D bipolar transistors and other devices, in MMIC's in the early 1980's. The difference was that they were much larger devices than the modern versions.
Everyone forgets that DARPA is often the mother of our modern invention era. They only focus on where commercial production ends up. A whole era of innovation in technology usually begins at DARPA

Thank you for this! I had to smile when you mentioned your father at NSC...that's where I worked first...at their first fab (I don't think we called them that at the time!) in Danbury CT
I cranked the volume on my headphones to force this information into my brain. Asianometry does a stupendous job of informing, what was, what is, and what's will be. Technology keeps throwing curve balls, Asianometry shows us the pitch.
Another outstanding video, great summary and great visuals. Slight correction: Intel moved to high k metal gate for 45nm. Their 32nm node was a shrink of 45nm, the second high k metal gate node, and, as you noted, final planar node. Samsung tried to squeeze one more planar process for 20nm, but it was a disaster. 14nm yielded far better with finFETs.
Yeah which is why his non semiconductor/hardware videos has more views. Hopefully he gets paid more (cpm) for the high IQ videos which are his signature ones.
I like these videos. I am no engineer, but I understand the "problems and hurdles" with new processes and like knowing more details rather than "there are yield problems with the new technology"
Very well written and paced, love the narrative! If I can make a suggestion, for those of us viewing at night or on a home projector, it would be great to show article screenshots in dark mode or at least a lower contrast background (something like the warm brown color of parchment) to reduce the sudden switching between graphics / photos / video and the full blast of a 255-255-255 bright white page of paper.
Great video, saw you got 400k subscribers now too! I remember when you only had like 40k but the videos were the same high quality and well researched as they are now. Glad to see you finally get the viewers/subs this level of content really deserves
It’s nearly twenty years since I was in the semiconductor industry, your videos give me an excellent insight into modern developments. Thank you for taking the time to make them.
Thanks for that explanation, I kind of actually understood this one a bit. Like in buildings, each floor you build comes free as you pay for the lot size only once. But the higher you go the more they cost per floor. Charles
Kind of, kind of not. In architecture, each new floor costs marginally so little compared to the marginal value it adds that it makes sense to build higher. A more apt analogy is that building higher was what they did before hitting the limitations described in the video. So finfets is as if now everyone would have to build cantilever buildings or buildings with holes in them to pass wind flow, to compensate for not being able to build higher. So in my opinion examples of "finfet buildings" might be The Link in Dubai (cantilever skybridge between two buildings) or 432 Park Avenue in NYC (a very tall building in comparison to its footprint.)
Awesome content as usual, spent 16 years in semi as equipment tech, late 90s to early 2000s started in military ceramic packaging and ended up in R&d fab dry etch, your content is fantastic thanks
You do a SUPER human job of taking theese abstract concepts and making them readily available to all. I am a technologist with almost foury years in semiconductors and learn something everytime I tune into your channel. Thank you for all your hard work!
Hmmmm... The way I see it, the next step is full 3d. Not merely adding 3d features to existing 2d basic structures, but outright building those structures in 3d, floating anywhere in the volume of the chip, all the way from up against the pads, to down against the substrate. If you can additively manufacture a gate, an insulator, and a channel, you can (probably) additively manufacture a source and a drain. Maybe even a structurally weak breakaway layer to save substrate. Maybe mixing sizes on a single chip for power and stuff. Added bonus: if you can stack logic on top of itself, you need less chip area for the same device size, allowing the use of smaller (and hopefully easier) photomasks (at the expense of more of them). Though it might be time to abandon photomasks altogether in favor of scanning the pattern (resin 3d printers do this exact thing at macro-scale).
Just want to thank you for making this content! There is not a lot of quality content on the industry I both work and am interested a lot and it's great to have something where I can say, hey I have worked on this or I have seen this or I found that interesting as well. I have shared this channel to so many customers and colleaugues I work with and shared on every unviersity or workshop lecture I gave, You are amazing!

Nice video, this info reminds me some words in the datasheets of some discrete power semiconductors transistors like: TrenchFET (Vishay), HexFET (Infineon-Int.Rect), SuperMesh (ST), HiperFET (IXYS) and CM2 (CREE). Some techonologies are for lowering the RDS_on and other to withstand high open voltage (some mosfet are rated to 1.7 kV OMG!)
I always thought HexFET sounded weird but didn't look it up until today. Turns out that it indeed consists of a hexagonal lattice as the name might imply. Zeptobars even has a die shot of it.
Really nice and interesting video, as always! Looking forward to your video on the next gen technologies involving superlattices and atomic layer deposition.
in spite of all the terrible going on in the world, its things like this that make you think that its really a great time to be alive and seeing all this happen.
Well, statistically speaking there was no better time to be alive. Never has a larger percentage of the human population lived in peace, didn't starve and so on. Problem is that nowadays you have the means to inform you about all the crap that happens anyways.

That was awesome video! Thanks and happy new year! I think at the moment the computing power in smartphones is sufficient to do all things I could think of. We are lucky that physics allows to produce stuff like modern smartphones without spending too much money, this limit could have been reached couple of years ago and that would mean laggy gps, slow low res youtube and no 3d smartphone graphics and no refresh rates above 60hz, with all mentioned stuff being available before that limit I am not worried too much. I might be a bit of a oldtimer (I just had my birthday today finished 38 years)
Executive summary: Great video! As a software person working closeto hardware I know much of the information in your video but not necessarily the background such as history or who invented what an its great to see all this information to be presente in around 15 min. Considering you also need to edit etc. these videos I'm sure you have Snowwhite's dwarves and many more minions working for you in the background ;-)
At 11:32, I believe fin pitch is the distance from center to center (or side to side) of adjacent fins. The area between fins is for electrical isolation to prevent crosstalk.
As developing new nodes gets more expensive, it'll just happen slower. Given time, paying for it is no question. Once the entire market has bought the last node and doesn't want more of it, the payoff for coming up with node n+1 becomes astronomical. Right now that's not the case, previous node is just a few years old, and node n+2 is coming soon enough, no problem to skip a node or few.
Long time subscriber but first time commenting, your videos has inspired me to go back to university to study electrical engineering as an adult learner. Thank you so much ❤
The true geneous of FinFET was it allowed scaling using traditional equipment. The next generation when likely be far to complicated and difficult to yield to be economically viable apart for millitary applications. The next evolution to home computing will be multi processor systems and a return to multi GPU architecture. As for improved efficiency we are at the end.
back in my school days (80's) asked my teacher why dont cars park themselves? My Teacher (Alan Bleasedale, i'll never forget you sir) replied.. "its already possible.. But it's a lot of cost. putting too much advancement into products that people cant realistically afford leaves a void. yes you a great thing, but you have no customers"
@@Palmit_ Yeah The same Fallacy present in all humanity lives there is many thing that or so called Artifacts has been created in the past that amaze us still this day but usually they only exist a few and only leader of a tribe, nation or a wealthy man in a nation with particular interest can afford it. Economic feasibility is what hold back innovations.
i feel like if programmers wrote more efficient code we wouldn't need so much computing power. there's probably a lot we can do in terms of WHAT gets processed rather than HOW it gets processed.
Hopefully N2 has good yield. Unless there is a major improvment in power consumption, smaller chiplets with high yield coefficient will be needed for any significant advance in value to the end user. It has been almost 10 years since N32 and I still don't see much incentive to upgrade, as someone that had a home computer all through the '90s when 2 years without an upgrade was a long stretch,that is shocking. A decade for few more cores that I rarely need, maybe 20% boost in clock speed, AVX512, compatibility with slightly improved motherboards (PCIe and DRAM generation bump), and maybe 5% energy savings [whole machine], all for the low low price of 3 times what I paid for the n32 based machine.
Your videos are absolutely amazing. Where do you get all this knowledge from? I'm taking mainly about electronics. I just want to find a way to increase my understanding of those topics.
Function Accelerated nanomaterial Engineering (FAME) focuses on nonconventional materials and devices incorporating nanostructures with quantum-level properties to enable analog, logic and memory devices for beyond-binary computation. Also financing their Center for Spintronic Materials, Interfaces and Novel Architectures (C-SPIN)
This is really the key issue. If cost/transistor stops declining, ever smaller nodes will become increasingly niche. You will get more bang for the buck by just stacking 28nm chips. For everything other than the most power constrained devices, it would make little sense to go below 28nm.
I really enjoy these videos. Can I ask if you have thought about doing a video on the rapid development of SerDes for semiconductors. As we continue to move bigger and bigger amounts of data we are going to need better solutions to move data as quickly as possible. I have been reading a lot about a company called Alphawave IP recently who do some really interesting and work were founded by ex intel employees.
The smaller transistors used less power because their capacitance was lower. There was a smaller amount of energy needed to transition the gate from off to on (or vice versa). This is what has enabled computers to become more powerful whilst not using more energy.
13:53 That comment from ASML's CTO about reaching the end of lithography is certainly interesting. If we're reaching the end of lithography, what is next? Is anything next? Some might say new materials, but a new material is more or less a one-time jump and an expensive one at that. I wonder if perhaps the next big game in town is innovating on the manufacturing processes/equipment to reduce the cost of going to higher layer counts.
We've been dealing with the exclusionary aspect of electrons (i.e. one signal on one lead) and how to work around it for a long time now. I truly believe photonics will be the future. The tech is still very immature, but we're already got photonic AI chips and photonic data relays on integrated circuits. Once we can figure out how to do the same sort of general purpose Von Neumann architecture or something analogous it will just be a matter of materials science on how to construct them at smaller and smaller scales.
While packing more transistors in a small space is already happening, clubbing quantum computing with it will add a new dimension to extreme computing chips in the near future. Imagine every nano chip is a super computer with terabytes of memory!
Protean transistors where each gate is a protean? Genetic engineering industry could help with that. Protean folding comprehensions has made a recent giant leap. Our cells use proteins like machines. We can use proteins like electronic circuits.
Hu Chenming, born in Beijing in 1947. Grew up in Taiwan, earned a scholarship for Berkeley UC. Chinese talent saved the proud American industry. Probably for the last time.
hey there's one thing i've been curious about and don't know where to find info on it. What are the current ideas on moving forward when EUV is too expensive to improve? Somewhere I heard a comment that there will be a change
Interesting to think they can make such complicated 3D structures using lithographic methods. One kind of wonders if this kind of technology would allow for some other potential things as well in due time. To bad the cost is only going up these days though, I guess they will have to find a way to reduce costs in future or accept things starting to slow down once more. Maybe some kind of self assembly technology could help here? Or will it be yet another extra cost? Well I guess we'll find out.
My thoughts on this are in the 90s it was already clear we see the end and I was still a pupil but one way I saw was 3D CPus . Yes I know like he said they are already do some more layers on the CPU/GPU these days but you can't go far with this because you trap the heat inside with this. I watched a video on youtube about a different type of transistors which solve this by not blocking the current but just switch over basically you have 2 inputs and 2 outputs with something like this it would be possible. The down side like he said such a unit would have 100th if not 1000th of layers basically ^3 the amount of transistors but even more the costs . This is not a consumer product.

A decade for few more cores that I rarely need, maybe 20% boost in clock speed, AVX512, compatibility with slightly improved motherboards (PCIe and DRAM generation bump), and maybe 5% energy savings [whole machine], all for the low low price of 3 times what I paid for the n32 based machine.
Your videos are absolutely amazing. Where do you get all this knowledge from? I'm taking mainly about electronics. I just want to find a way to increase my understanding of those topics.
Great videos as always
Thanks much for such a wonderful explanation!
Absolutely fascinating - love your videos!!! Wonder what darpas cooking up now 🤔 🧑🍳
Function Accelerated nanomaterial Engineering (FAME) focuses on nonconventional materials and devices incorporating nanostructures with quantum-level properties to enable analog, logic and memory devices for beyond-binary computation.
Also financing their Center for Spintronic Materials, Interfaces and Novel Architectures (C-SPIN)
Loved the animations.
I choose to believe "GAAFET" is pronounced "Gay-Fet" because it sounds funny
So NVIDIA is just getting in early and conditioning the consumer market for future higher prices with $1000+ consumer GPU boards...
This is all amazing!! we live in awesome sometimes. Thanks Asianometry.
Who needs 3D animation? When you can innovate with boxes! Love the videos
Extremely interesting one! Thanks!
thanks for another great video about super technical subject
Good summary and video. FYI, your arrow showed the FIN space cd, not the FIN pitch.
This is really the key issue. If cost/transistor stops declining, ever smaller nodes will become increasingly niche. You will get more bang for the buck by just stacking 28nm chips.
For everything other than the most power constrained devices, it would make little sense to go below 28nm.
10:30 This is about a decade after Digh Hisamoto's publication.
I really enjoy these videos. Can I ask if you have thought about doing a video on the rapid development of SerDes for semiconductors. As we continue to move bigger and bigger amounts of data we are going to need better solutions to move data as quickly as possible. I have been reading a lot about a company called Alphawave IP recently who do some really interesting and work were founded by ex intel employees.
Thanks Jon
Absolutely fascinating
The smaller transistors used less power because their capacitance was lower. There was a smaller amount of energy needed to transition the gate from off to on (or vice versa). This is what has enabled computers to become more powerful whilst not using more energy.
I like zero hype ending. No corporate channel would do that, as they need to lie if this means more engagement
They'll probably go with nested octangonal offset so you can closely pack 9 gates per sequence.
I like Hu Cunming’s book about the basics of semiconductor devices
damn... this is so well researched.
Thanks for making this! It's not just a fad.

Amazing content on amazing technologies

HafniumOxide is NOT a metal.
its a crystaline salt like every other oxidized metal.
13:53 That comment from ASML's CTO about reaching the end of lithography is certainly interesting. If we're reaching the end of lithography, what is next? Is anything next? Some might say new materials, but a new material is more or less a one-time jump and an expensive one at that. I wonder if perhaps the next big game in town is innovating on the manufacturing processes/equipment to reduce the cost of going to higher layer counts.
I've heard about "electron beam" (?) lithography?
And now in 2023 we have gfxs with 4nm processors, everytime we think we hit the wall, some geniuses finds a new way.
We've been dealing with the exclusionary aspect of electrons (i.e. one signal on one lead) and how to work around it for a long time now. I truly believe photonics will be the future. The tech is still very immature, but we're already got photonic AI chips and photonic data relays on integrated circuits. Once we can figure out how to do the same sort of general purpose Von Neumann architecture or something analogous it will just be a matter of materials science on how to construct them at smaller and smaller scales.
I remember there was a 1979 Scientific American article about 3-D chip architecture...but cooling made it impractical!
While packing more transistors in a small space is already happening, clubbing quantum computing with it will add a new dimension to extreme computing chips in the near future. Imagine every nano chip is a super computer with terabytes of memory!
Let's chat Whatsapp ☝️☝️
Protean transistors where each gate is a protean? Genetic engineering industry could help with that. Protean folding comprehensions has made a recent giant leap. Our cells use proteins like machines. We can use proteins like electronic circuits.
Great video!
Thanks!! :)

hey there's one thing i've been curious about and don't know where to find info on it.
What are the current ideas on moving forward when EUV is too expensive to improve?
Somewhere I heard a comment that there will be a change
Interesting to think they can make such complicated 3D structures using lithographic methods. One kind of wonders if this kind of technology would allow for some other potential things as well in due time.
To bad the cost is only going up these days though, I guess they will have to find a way to reduce costs in future or accept things starting to slow down once more. Maybe some kind of self assembly technology could help here? Or will it be yet another extra cost? Well I guess we'll find out.
My thoughts on this are in the 90s it was already clear we see the end and I was still a pupil but one way I saw was 3D CPus . Yes I know like he said they are already do some more layers on the CPU/GPU these days but you can't go far with this because you trap the heat inside with this. I watched a video on youtube about a different type of transistors which solve this by not blocking the current but just switch over basically you have 2 inputs and 2 outputs with something like this it would be possible. The down side like he said such a unit would have 100th if not 1000th of layers basically ^3 the amount of transistors but even more the costs . This is not a consumer product.
6:25 What’s the pest control cockroach boxes are used as illustration for channel and gate? :-)
Thanks!
@12:25, looks like a dental x-ray
