Many thanks to science and technology company Merck for sponsoring this video! Find out more about directed self-assembly and the past and future of microchips by listening to their podcast about it: www.merckgroup.com/en/future-talk/1592785/?ko=anst Edit 25/03/2023: So sorry to hear about Gordon Moore today. www.bbc.com/news/world-us-canada-65073812 His name will forever be synonymous with a half-century of impossible-seeming technological progress. This video was made well before the news but it seems fitting that I released it just in time to be a tribute. RIP Gordon Moore-but may your Law live on.

This is the greatest explanation of EUV i've ever seen. You did really great 🎉

You skipped over the part where they used interference patterns to create structures smaller than the wavelength of light used

I skipped over quite a bit to be fair! :) But that is incredible too!

Great explainer graphics as always, now I feel more sympathetic after being stuck on 14nm with ever increasing TDPs for half a decade! Didn't realise how much of a problem the UV light wavelength was during fabrication as most of the tech coverage for laypeople like me emphasises the issues with transistor size and electrons.

please make videos on quantum mechanics ,how to approach ,your expereince and etc

I think in the early nineties, there were attempt to combine rhodopsin and lasers as logic gates to replace semi-conductors, I don't know whether the idea went further than scribbles on the back of an envelope.

Brilliant video Andrew! Very Fascinating explanation!

Thanks! And good question…maybe something quantum?! But I’m guessing not for a while! The great thing about materials is that they give us the power to control the subatomic particles (ie electrons) that are doing the real work!

You'd need to keep the chips at almost absolute zero (degrees Kelvin) or probabilistic quantum effects would take over and crash your OS every other nanosecond...

The whole self assembly idea makes me wonder: solids don’t usually mix with each other, so I assume they will be liquids, or solid + liquids and that just feels like growing something, with extra steps. What a time to be alive, needing to “grow” microchips to make them smaller.

@DrAndrewSteele

Жыл бұрын

It is a wild time to be alive! And the self-assembling molecules are usually dissolved in something, so they’d be solid in bulk but they’re able to move around in solution and find the right way to self-assemble. :)

Slightly jealous you got a computer as early as 1993… I had to wait another four years! But remember the 486 fondly from a friend’s house (well, remember Doom on it fondly)

Computers starting to get exciting again, there's nothing like a limit to bring out creativity.

Definitely! In the short term I think we’re going to do amazing things redesigning chips for specific applications, like the various tensor chips for machine learning but on steroids…and then who knows what amazing stuff new materials will allow. Bring it on!

Why so many mirrors if they’re that bad for the power?

@DrAndrewSteele

Жыл бұрын

I don’t know the exact optical details, but I’m sure the engineers tried to minimise the number for exactly that reason! My guess is it’s because you can’t make a single mirror that reflects the light precisely enough: there are a number of issues known as ‘optical aberrations’ that basically make it impossible to precisely focus light if you’re just using one mirror or lens. It’s the same reason camera lenses have multiple glass elements-one on its own would have an image that was blurry at the edges/brought different colours to focus at different points etc, but by combining a few different ones together, you can ‘cancel out’ these optical errors and get a sharper image. :)

I thought videos were 24FPS and only video games were 60FPS (or more commonly 30, these days). Why is it so important to keep Moore's Law going?

@DrAndrewSteele

Жыл бұрын

There are loads of video frame rates! Common ones include 25, 30, 60 and 29.97 and 59.94 (don’t ask)…while games usually display at a variable frame rate depending on how fast your graphics card is! And it’s important to keep Moore’s law going because so much of our society and economy depend on faster, more power-efficient computing. :)

13:33 "Current chips are flat" that's not 100% true. FinFET is a technic to make 3D transistor, and the first "stacked CPU" are already on the way with Intel EMIB and Foveros

fastest ever running cpu was an Intel i9 13900k 9008.82 MHz before that it was AMD FX‑8370 @ 8722.8MHz and today they even run at 5ghz easily

YES IT IS A GOOD VID BUT WHY NOT JUST USE X-RAYS OR SOMETHING LIKE THAT. I really don't get why you need EUV when much higher frequency light is much easier to make.

@DrAndrewSteele

2 ай бұрын

It is something they’re thinking about for the next generation of chips…but there are still challenges making the X-rays monochromatic (or just one wavelength), and finding chemicals that react to them.
