US Bans Export of Tech Used In 3nm Chip Production On Security Grounds (theregister.com) 73

The United States is formally banning the export of four technologies tied to semiconductor manufacturing, calling the protection of the items "vital to national security." The Register reports: Announced Friday (PDF) by the US Commerce Department's Bureau of Industry and Security (BIS) and enacted today, the rule will ban the export of two ultra-wide bandgap semiconductor materials, as well as some types of electronic computer-aided design (ECAD) technology and pressure gain combustion (PGC) technology. In particular, the BIS said that the semiconductor materials gallium oxide and diamond will be subject to renewed export controls because they can operate under more extreme temperature and voltage conditions. The Bureau said that capability makes the materials more useful in weapons. ECAD software, which aids design for a wide range of circuits, comes in specialized forms that supports gate-all-around field effect transistors (GAAFETs), which are used to scale semiconductors to 3 nanometers and below. PGC technology also has "extensive potential" for ground and aerospace uses, the BIS said.

All four items are being classified under Section 1758 of the Export Control Reform Act, which covers the production of advanced semiconductors and gas turbine engines. Those types of technology are also covered by the Wassenaar Arrangement, made in 2013 between the US and 41 other countries, which functions as a broader arms control treaty. "We are protecting the four technologies identified in today's rule from nefarious end use by applying controls through a multilateral regime," Assistant Secretary of Commerce for Export Administration Thea D Rozman Kendler said in a statement. "This rule demonstrates our continued commitment to imposing export controls together with our international partners."

The reason for the addition of the four forms of technology to export controls is a change made in May to how the BIS characterizes emerging and foundational technologies. Under the change, such tech was reclassified to be covered by Section 1758. The BIS statement announcing the export ban made no mention of the countries, but recent events make it clear the target is China -- the US has been considering other tech export bans (and investment freezes), recently all of which appeared tailored to target China. Analysts in the Middle Kingdom have claimed the ban would have little short-term impact on China's chipmaking industry as no one in China has yet managed to design chips as advanced as those targeted by the ban.

      Encryption export controls actually prevented other countries from buying such technology. From that point of view it worked.

        Have a look at the history section of the Wikipedia article for Pretty Good Privacy. [wikipedia.org]
        I like this bit:

        ..in February 1993 Zimmermann became the formal target of a criminal investigation by the US Government for "munitions export without a license". At the time, cryptosystems using keys larger than 40 bits were considered munitions within the definition of the US export regulations; PGP has never used keys smaller than 128 bits, so it qualified at that time.

        I had to download it from a server in Sweden, which is what everybody who needed it did.

        So export controls didn't really work.

        Not so much. The math and theories of various forms of encryption were widely known in international circles. Writing the code to implement encryption is not a capital intensive endeavor. Zimmerman may have "exported" the PGP source under cover of copyright. But that only facilitated its international interoperability. Had some foreign intelligence service wanted their own encryption tool suite, they could have easily written it from first principles.

        • If you look at much more recent, and more relevant, examples, they've successfully limited the level and types of encryption used in international versions of large swathes of available software. In a modern age where few users know how to do any differently other than download something else from their app store, which often leads them to install software tailor-made to allow intelligence agencies to monitor them and discover threats.

        Encryption export controls actually prevented other countries from buying such technology. From that point of view it worked.

        In the long run, it had the opposite effect because companies developed encryption software outside of America to avoid the controls. So America lost market share and lost expertise.

        If you were starting a company to produce high-bandgap semiconductors, would you locate it in America, where your market is limited to America? Or would you manufacture elsewhere, so your market is the whole world, including America?

        • It doesn't matter if the encryption is so good that we won't sell it, or so bad that we will, either way nobody is going to use it and they will have to develop their own.

        • CORRECT! Thanks to "Clipper" and derivative ideas of toothless "privacy", French, and to a lesser degree, German providers stepped in, principally selling into the networking business.
  • I don't really believe in interfering higher powers ... but it can't just be a coincidence that I happen to be eating fish and chips and an article on chips appears on slashdot. Maybe Jesus is real and trying to tell me stuff. Also, why now?

    • Well, it seems to be UK Jesus that is interfering in your experience, so you're basically screwed. Time to keep a stiff upper lip while you're made a martyr that achieves a minor symbolic victory for some vanishingly small cause.

  • From the brief: " Analysts in the Middle Kingdom have claimed the ban would have little short-term impact on China's chipmaking industry as no one in China has yet managed to design chips as advanced as those targeted by the ban."

    Isn't that the point of the ban, so they can't buy it, but there's nothing to stop them from eventually developing it. I mean, really, are you saying that Europeans and Americans are smarter than the Chinese in developing this tech? I'm sure the Chinese will do it on their own.

      China doesn't invent. They just steal and save the R&D expense. All the smart Chinese moved to another country leaving behind only those to scared of the Chinese threats. Back in the day the Russians held entire family's hostage to make sure their top tier scientists could not leave the country. I'm sure China uses the same playbook today.

        That is not true by a long stretch. Yes, they are stealing LOTS of western tech. BUT, that is to catch up. Once they understand it, then they engineer the fuck out of it.

        If u want to stop this, then:
        1) control the flow of Chinese students to the west.
        2) control the grad students doing R&D in America. Most Chinese profs hire check nese grads that then take the tech back to China ( many times, illegally ).
        3) look at the diversity regulations. Those are killing us when applied to tech.
        4) finally, take spying as a serious concern. It is constantly happening.

        The term "3 nanometer" has no relation to any actual physical feature (such as gate length, metal pitch or gate pitch) of the transistors. According to the projections contained in the 2021 update of the International Roadmap for Devices and Systems published by IEEE Standards Association Industry Connection, a 3 nm node is expected to have a contacted gate pitch of 48 nanometers and a tightest metal pitch of 24 nanometers.[14] However, in real world commercial practice, "

    A lot of companies claim to be able to segregate the design from the manufacturing facilities, and create their chips and circuits in China, but keep the actually technology and design secret. That of course is complete horseshit. I started looking at this after a conversation (in first class) while flying out of Denver, with a guy who has a company doing contract manufacturing in China. That was his line: we make sure the manufacturing and technical details are completely separate. Turns out there are a lot of those twats who say stupid shit like that, basically lying as if it were even possible. And so many people who want to believe them with dollar signs in their eyes greenlight it (obviously I'm talking about politicians).

    • China has a 7nm fabrication facility, but they cannot quickly turn out new chip designs like TSMC. The masking process is very difficult for 7nm and sure you can develop a chip with mediocre yields, but the time it takes to make the next iteration is very long. It's concerning to the the USA that they got this tech at all, but they actually aren't very far along with it. TSMC is moving to 3nm now, 5nm is mature and new designs are very quick to production.

    Go read the munitions list. If almost anything mentioned in there as banned actually existed society would be many, many times better.

    It bans things like air filters that remove 99.9% of diesel fumes such that the air can be re-breathed over and over in sealed environments for tanks. It bans 3d 6-axis fillament weaving machines that supposedly are not possible to make.

    It bans shape changing blades on aircraft and helicopters, like that silent one we got BinLaden with that crashed and we spent huge efforts to blow it shreds? (because its illegal to have but we had it)

    That treaty basically alludes to a secret amazing science capability that makes me sick because it isnt shared with society. Filters that would solve pollution issues but we pretend they dont exist.

    Did you know it bans diesel engines with super high outputs? Gas with its horrible knock issues limits itself but diesel can actually scale up to such high outputs per liter that they needed to ban it.

    Imagine society having diesel engines making over 2000 horsepower per liter. We would only need small lightweight 0.1 liter engines with outputs this good. Embarrasing F1 engines.

    If this crap existed, we should have it. But its hidden behind secret military uses that never benefit mankind. If it doesn't exist then why are there pages in these treaties calling out these limits as illegal? Why are these limits raised from old 2006 revisions of the treaty to now if this stuff doesnt exist?

    Encryption is allowed on any "off the shelf commercial cpu" but NOT on military designed chips. If there were no backdoor then why call this out? Why ban Encryption with user adjustable parameters besides keys? Well it makes supercomputers in Utah less useful if they cant crack Encryption made the same through regulation.

    Go read the Wassenaar munitions list. Its amazing what is banned. Its the one time secret advances are discussed out in the open between nations. It DIRECTLY shows what they have developed in secret with your tax dollars while you choke on fumes in the street.
