  • 28nm is the nominal resolution of the scanner. The chips that can be made with a single exposure. In that measure no ASML DUV scanner is 7nm either. The physics of 193nm light makes it impossible for any DUV scanner to have a nominal resolution of 7nm. 7nm chips are made using DUV by exposing 4 times at a 28nm resolution. The same quad patterning techniques allows 22nm chips to be made with a 90nm machine.

    The name is also misleading 7nm chips aren’t sub 9nm. TSMC’s 7nm chips are physically 10nm. The marketing names haven’t matched for years. It all started when TSMC sold 20nm FinFET under 16nm branding as they believed the addition of FinFET gave it 16nm performance. Then the entire industry adjusted their naming conventions to match with TSMC.

    SMIC, Huawei didn’t get to where they are by compromising. They never would’ve bought the Chinese domestic alternatives if not for sanctions. Price doesn’t matter in this industry, what they’re looking for is the best in the market. This is not the type of capital equipment that subsidies can sell. Which is why when US scanner manufacturers couldn’t compete with ASML, they completely failed as economically viable businesses and their assets were sold off.


  • China prepared for this 17 years ago. They launched the “02 Special Project” all the way back in 2006. The companies established by those grants have existed years before the sanctions. They were able to develop the products but selling them was another thing entirely, until the sanctions hit causing a massive boom in their revenue. People forget that it was market conditions that killed GlobalFoundries 7nm effort not technical issues. The same reason UMC gave up on anything more advanced than 14nm. Sanctions created the inevitability of Chinese 7nm by wedding the world’s largest telecom equipment vendor, Huawei to SMIC.

    It’s an amusing coincidence that by the time ASML will no longer be granted export licenses for their 5nm capable DUV scanners, the NXT:2000i and above, SMEE will be selling a 7nm capable scanner, the SSA/800-10W. A machine easily comparable to the NXT:1980Di that TSMC used to develop their N7 process. The fact that the NXT:1980Di and anything less advanced than it isn’t going to be export restricted is an implicit acknowledgement of the Chinese capability of making competing machines.

    5nm capable DUV scanners, such as the SSA/900 still in development, might be a requirement for SMIC N+2 however as the “7nm” Kirin 9000S is only 2% larger than the TSMC N5 made Kirin 9000. That suggest a density far exceeding anything any other foundry has been capable of with just DUV, such as Intel 7 or TSMC N7/N7P.

    Applied Materials and LAM are less of an issue. AMEC has been selling 5nm etching systems to Samsung and TSMC for years.

    TSMC made Kirin 9000 ran out in 2021, P50 Pro was the last phone to use it and the Kirin 820 ran out in 2022. It’s only the 5G base stations that still use TSMC made HiSilicon chips.



  • The only Nintendo console I ever had was a Famiclone so I don’t really have much nostalgia for their games.

    It’s just Nintendo ROMs that are disappearing. It’s still easier than ever to find even the most obscure classic PC games on abandonware sites and GOG compilation torrents. It’s also only the SEO abusing ROM sites that are vulnerable to Nintendo’s attacks. Complete ROMsets for their consoles can still be obtained through torrents, Vimm.net, and the r/ROMs megathread especially for the older cartridge consoles.

    Emulating a current gen Nintendo console has never been as good as it is for Switch emulators. Any new PC can emulate Switch Triple As at full speed. Android is getting builds of the Yuzu emulator and mobile SOCs have enough power to run less demanding titles. When a lot people who don’t even own a Switch can play Tears of the Kingdom, Nintendo is understandably trying to crack down. The portable aspect of the Switch is no longer a unique advantage. It used to be just GPD making those handheld PCs now every brand is trying to compete in that form factor.

    Honestly I think the state of emulation in general is experiencing a golden age.

    Retroid, Anbernic and AYN are making hardware that is a better solution for most people than trying to jailbreak and refurbish old original portable consoles. The screens, the analogs and the buttons they use are as good if not better than the first party hardware. Unlike bulky handheld PC, their Linux or Android based emulation handhelds are still in the same size and weight class as the PSP.

    A couple years ago the Xbox 360 and PS3 emulators were basically just experimental demos. They weren’t stable enough to actually finish any game on and most CPUs weren’t fast enough to run them at full speed. They’re still hit and miss but the list of playable titles will only ever grow.

    It has come to the point that the PC can play everything. All previous gen consoles aside from the OG Xbox have emulators at a playable state. There are almost no current gen console exclusives anymore as the PC is getting ports of PS4/PS5 exclusives, the XBone/Series never had any to begin with, and of coarse the aforementioned Switch emulation.
