this shit is ancient, 30 years old node and russians had access to smaller nodes anyway (90nm) https://www.youtube.com/watch?v=N_4R4X7AWtU this is situation from 2022, doubt it got much better, could even get a fair bit worse

So, it’s obviously nothing like an across-the-board replacement, but you can make useful chips that aren’t the latest and greatest.
If you want to do performance-competitive CPUs or competitive signal-processing for radars or whatever, then it won’t work.
But let’s say that you want to make a voltage-regulator chip (something that I know we have put on sanctions lists for Russia). Power supplies need those, so you’re gonna pretty universally want them. That doesn’t need to be particularly high resolution.
Think of all the problems that automakers had due to COVID-19 chip disruption. That was mostly over old, low resolution chips…but they had to have them to ship cars. The article specifically mentions auto manufacture.
Microcontrollers do a lot of work in consumer electronics. Probably have one in your microwave oven. Not very fancy, but it lets you plonk logic in in software.
Russia can probably smuggle in some chips. But that’s expensive (because criminals are going to want a premium for their risk) and risky. Let’s say that you’re trying to buy sanctioned CPUs in Kazakhstan from sketchy parties.
Maybe one of those parties is a (comparatively) upstanding smuggler getting you the real thing and just charging you an arm and a leg.
Or maybe it’s from some enterprising party selling counterfeits, because now the original manufacturer isn’t gonna be working with you to verify that the stuff is authentic, and that knockoff doesn’t have the same testing and has some problems.
Or maybe the person you’ve run into is with the CIA and intending to poison your sanction-busting smuggled supplies of chips with backdoored or sabotaged versions.
Russia will source what it has to from the black market, but the less stuff in their supply chain that comes from the black market, the better-off they are.
Well that was a double take
You had us in the first half not gonna lie
people got to the moon on less.
I think that behind those “oh, it’s 30 years old” people miss one thing:
350nm chips are perfectly alright for many things. Simple controllers, chips inside various appliances, even some of the simpler military tech can absolutely rely on those chips.
It is way more than nothing.
Ya but would you like a yield of 100 cpus per slab, or 5.000 ?
So it’s a question of cost too I think, not an expert OFC.
Probably 20 per slab, and an annual yield of about two slabs combined. Of course it will only run for a month before breaking down, due to some vital part going missing.
Yep. Look at it this way, those $100,000+ machining centers that make nearly everything you use and own, are running on basically 486 chips. And they only transitioned from the 386’s because the dies wore out and the chip manufacturers said they weren’t going to remake them. It caused a noticeable amount of angst in manufacturing when the news got out.
Yeah, not to mention some low level engineers that built it only using a hairpin, a hammer, and a lithography machine … (ofc joking, but I bet there are like five nerds that basically made it all happen).
Yeah, those old fans are still useful. Here’s what Microchip Technology Inc runs:

See page 6.Their fab in Lawrence, MA only goes down to 1000nm. Their other locations go down to 250 or 110nm. IIRC, some of that is the auto industry refusing to port things off of old chips, but the point is that you can do a lot of useful stuff with horribly outdated fabs.
That’s like late 486 early pentium 1 era. You don’t need a supercomputer for everything. The chip situation could be much shittier.
Are they telling the truth though?
we landed on the moon with those
With much worse ones*
Plus I would guess that few country could also rebuild the whole manufacturing process in a few years?
I like how the article shits on Russia like
In every civilized nation of the world, 14 years olds make these in their bedrooms, but since a bunch of Ivans can’t stop drinking spoiled potato juice, it took Russia 35 years, haha!
Uh… They’ve definitely assembled more than just one lithography machine. Probably over 80 years ago. Is it just me or is that a weird headline?
