It's not sad, it's just the way it is. No one can fully understand the implications of quantum mechanics (namely entanglement), which is why there are so many interpretations of the same observation. Look up the double-slit experiment and tell us that doesn't blow your mind.

Not really, quantum physics is very un-intuitive. The fact that an electron doesn't exist in any particular place or time (and is just a probability wave of being somewhere) until it is observed is something spooky that no one really understands. There's nothing like that in classical physics. Or the fact that two entangled protons can be a universe (or any length) apart and still affect each-other (instantaneously, breaking the laws of relativity).

That was a brilliantly clear and energetic overview of modern chipmaking. Professor Moriarty explained how a Silicon transistor works, but didn't label it as such. The Silicon substrate is formed into the transistors by adding impurities (doping).

Wow, that was was barely within what I could follow all the way through. The few times I started to get lost he stopped and explained it a bit more. Very well done, and I even picked up a few new things.

This material is way over my head, but this video was fascinating. Thanks for putting it together.

Unfortunately the 5nm and 7nm are really brand names than actual sizes of features - they are usually much more refined 10nm process which are capable of higher densities by eliminating issues with previous 10nm and 14nm processes. Essentially we are right up at the limits of manipulatable sizes when it comes to computing - most every improvement now comes from extremely complex and well designed architecture - cache for instance which is what amd rides on for their superior processing of late with 5000 and coming 6000 series chips

Plants are being constructed in Arizona, Tainan, etc. with 2 nm coming in 2025 - call it creative naming or fudging on the numbers - each new plant builds a smaller process. People don't invest and they don't spend over a hundred billion to convince you, you are not convinced. Instead the money is spent to place billions of transistors in the space previously occupied by one transistor, decades ago. They really are getting smaller.

@Sakkura1

The wavelengths they're using in mass production today are not that small. I believe 193nm is still standard, even though they're making features as little as ~14nm in size (actually many parts of a "14nm" process are not 14nm, but it's all pretty much to scale compared to older process nodes like 22nm). The next step is (supposed to be) EUV, where they do drop to very short wavelengths and high energies, as discussed in the video. They are having a lot of issues getting that to work for mass production though.

@davesextraneousinformation9807

The diffraction of light really is a limitinig factor when reducing the size of features. One of the ways semiconductor manufacturers get around this is phase shift masking, which Prof. Moriarty explained as two masks just slightly offset from each other.

+sewer renegade There are actually several ways of masking phase shift masks. I think Professor Moriarty is portraying the general concept of setting up having the edges of the photomask phase shift the light passing by so that when the light reaches the photoresist on the wafer, the edges of the patterns are being enhanced by constructive and destructive interference of the light waves, thus making features smaller than the wavelength of light possible.

Really cool to see semiconductor fab processing explained here!

This interview elevated my understanding of how we're able to manipulate atoms. Thank you.

this is great info, since I come from a physical science background this shows the application of what I learned, wish they had a class on the physics of computers

The physics and technology in making the 13.5nm light that is talked about here is some of the most advanced applied physics in industial RnD going on im the world today. Primarily this work is done close by to you, in The Netherlands. I would love to see you or Brady make a video on it. great job on videos. From another Irish physicist.

Love this guy and his energy. Great talk as well.

You're a gifted explainer of these topics.

I really liked this sort of unplanned interview

You said the wavelength is a limit but the nobel prize last year was for the invention of microscopes which overcome this wavelength barrier. I think they used the light emitted by proteins and blocked the light emitted by neighbouring proteins so that the resolution was down to one protein. There might be a way to use that for making smaller chips.

Physics AND computer science, all with Professor Moriarty. Great combo, I really enjoyed this episode. Thanks guys!

It's very interesting to dive into the physics and chemistry of electronic computing, it's not a subject I've explored much as a computer scientist.

Watched extra bits, still want more.

This was a really good video. Lots of detail. Could you do a video about error checking/handling in chips (CPU's). I read a few years ago that now CPU's are becoming smaller, there are more errors in the calculations. I would love to know how manufacturers get around the errors.

This guy is magic, and clearly loves his stuff. Excellent.

Big man working on small stuff, respect

I could listen to this guy for hours

I brought up the fact that Chemistry and Physics and ultimately everything that follows is a seamless whole just divided into digestible parts to a chemistry instructor once, and he almost flipped his lid. It was almost the same reaction from the physics department, yet they worked together constantly on things, though the chemists tend to be more reserved and the physicists tended to let their reservations go a bit, especially on things that went "boom". Nice to hear the Professor say nearly the same thing, about the relationship.

I freaking love this video, man.

I thought that the wave interference of the photons (as in, interference you see with the double split experiment) would be come a problem. But instead you could create a mask that actually utilizes this phenomenon to create interference patterns that match the target pattern on your silicon sheet.

Great video, I'd love to see more like this

This is awesome! More videos like this please!

silicon is reflective? MIND BLOWN.

To elaborate on the "Layers" question, yes, it's very much done in layers. In fact, even the first layer wasn't fully described here. After the exposed (or unexposed, depending on the process) areas of the polymer are washed away, another layer of some material is applied. Then the places where the polymer remained are washed away, leaving the new material only in the gaps. The material can be dopants for the underlying silicon, metal layers to connect components, insulating layers to separate things, etc. It can even be exposed to etchants, rather than a new material, to remove whatever layer is showing.

great stuff, hoping for more stuff about chip manufacturing and such :)

Great video... More of Professor Moriarty!

Amazing video. Learned a lot.

My fiancé worked for Intel, he was sent around to various clean rooms and such to work on the computers that were running the electron scanning microscopes that they were using for debugging chips. The whole process is pretty cool to me, as I just stopped learning the abstractions of the CPU at the logic gates, and VHDL design. A curious wonder, what kind of feature size would a hobbyist be able to achieve? I mean, there's that guy who built a macro-computer by using full chips for his transistors, and I know most of us are better off using FPGAs anyways. But say someone wanted to get into etching their own silicon, what do you think would be the range of quality that they could get to?

My "like" happened at 7:05. The "quantum computing" question wasn't very well informed, though it may have highlighted a common misconception. The answer, spurred from the question, about how "classical" computing must necessarily exploit the quantum nature of matter if it intends on reaching ~1nm scale features is totally spot on. Looking forward to the next ~5min of video!

Amazing video! I have a question about Professor Moriarty's explanation of how the semiconductor industry is able to create such precise patterns on transistors. When the two offset masks are placed over the silicon wafer and light is shown, how is it that the light is able to deterministically etch a pattern? Why would it not behave like a wave/particle in the double slit experiment and defract into a probabilistic wave pattern on the wafer?

I loved this! So informative :)

I'm just glad there's someone that can see that physics chemistry and computer science are integral to each other than the normal 'brinksmanship' that you see in these fields.

This makes me so excited/happy!! :D

We missed you!

I was wondering, what is the limiting factor in hard drive size, both physical and storage related? if you could do a video explaining, that would be appreciated.
