Not an electromagnetic field, an electric field.

An electromagnetic field always means photons (light, microwave, radio, etc.) no exceptions. That's why it has the "electro" part and the "magnetic" part; photons are an alternating electric field and magnetic field.

Field Effect Transistors just use an electric field, that is, a charge. Nothing magnetic.

4:43 ❤ High Yield is by far the most handsome and smartest of us two. Don’t be deceived!!!

[kevikiru]

It's clear that High Yield's first language is not English yet he is so eloquent in speech. Even more interesting is the fact that he is speaking about complicated language to probably a technically competent audience but not very sophisticated but still very understandable. And he keeps attention without the repellent clickbait and over-hype. This is just lovely!

I'm working on a GAA tapeout right now. From an analog designer's perspective, the transistors perform great, but my god the ever increasing layout rules a nightmare. In addition, the lack of multiple oxide thicknesses makes anything that faces the IO a significantly higher challenge.

In all honesty, I think back-side power will have a significantly higher impact on performance than the move to GAA.

Wait, how do I notice this only now. You where my University Professor I took my "Wahlpflichtmodule" using FPGAs. Still the most fun modules I ever signed up for.

shows FinFET
I'm getting old.

Dang ASM looks so cool ! I am definitely buying one of their machines, but I'll have to wait till black friday for the discounts !

[DigitalJedi]

Hello once again from Intel Foundries! I've been loving to see all the coverage these new nodes are getting. Intel has moved me on from 18A fully now that Panther Lake has powered on. I don't have all the info and can't give all of what I do have, but I'm happy to field questions again.

[bastiangugu]

Great shoutout to Asianometry. His videos are always very interesting, not only on semiconductors. 🙂 But I'm also very glad to have found your channel. It was through a video by Tom from MLID. So the journey continues.

[hytalefanboi]

It's a good day when High Yield drops a new vid

[supramentalmanifestation]

I know nothing about semiconductors and loved this video. Thank you!!! Investing in Atomera actually brought me to find your video, not the algorithm.

[christophermullins]

When you said "thats the 'field effect'" many things vame into perspective for me. You do such a great job explaining these topics. ❤❤❤❤❤

[sgt_mate]

Took me a few minutes to bring back my knowledge on fet but I think I got it now. Thanks for bringing back and enriching my knowledge.

[shmookins]

Ah, you abruptly stopped at the forksheet/fork design. I was so engrossed in the whole video and was very curious about this new fork method.
Excellent video, friend. I'm off to look for this fork idea.

[Vinzmannn]

I think this was a nice explanation. Also really nice of you, shouting out a much smaller youtuber like asianometry.

[EntekCoffee]

Nice video! One detail you might have missed is that in GAA, assuming that it's a perfect structure, you can have multiple different FET channels coupled together by one gate. This could be handy in many situations. If individual channel growth is controllable enough, you can also have multiple independent FETs in the same area of what used to be one FinFET. This would increase transistor density exponentially. Plus, you can also make FETs that interacts with each other vertically through simple or even quantum (!) interaction! It's Sci-Fi for now but many research labs are very successful in these already (especially in sub LN2 temperatures).

However, the issue is with cost (which implies simplicity). The very reason why Silicon has been the material we all know is that we can get away with as little epitaxial growth as possible. It is the jack of all trades that is extremely cheap and easy to work with. Consequently, the traditional "silicon planar process" never included any epitaxial growth, except for the metal parts. Only etching, doping, oxidation, and lithography was needed.

While certainly unproven, Rapidus is also supposed to start producing 2nm in 2027 presumably using GAAFETs. It would be interesting to have 4 cutting edge foundries if they can do it.

[karlstathakis]

This is rapidly becoming one of the best channels on YouTube

[shuginubi]

Just thinking about the indomitable human spirit willing to take on such an immense task as wrapping those tiny channels. Just mind blowing.

Good to see you on Moore's Law is dead man!
Hope to see more content from you soon.
