Huawei's New Mystery 7nm Chip from Chinese Fab Defies US Sanctions

  • Until we get more data/testing from people outside the country, I am going to remain skeptical that it isn't just another chip they re-engraved and changed what your computer will say it is. Doesn't matter which country it is, I don't trust the data unless a neutral 3rd party from outside the country is able to fully confirm whether the claims are true or false.

    I'm also skeptical since they had absolutely no PR about it before a US official went over and that (unless it's changed or I am misremembering) Huawei didn't even put out any official stats on the chip itself and instead let the tech bros in country do it instead (which to me screams a little bit of a red flag).

  • This is the best summary I could come up with:


    In another Global Times publication, Chinese analysts labeled N+2 as SMIC's 5nm-class production node about a year ago.

    Yet, there are independent proofs from TechInsights that SMIC produced MinerVa Semiconductor Bitcoin mining ASICs on its 7nm-class N+1 technology.

    Meanwhile, SMIC's Twinscan NXT:2000i deep ultraviolet (DUV) lithography scanners can make chips on 7nm and 5nm technologies, so that the company may have developed a 5nm-class fabrication process.

    Huawei's HiSilicon is China's most successful chip designer that has used to adopt TSMC's leading-edge fabrication technologies.

    After Huawei lost access to American technologies in 2020, HiSilicon could no longer work with the world's largest contract maker of chips, and it is believed that the parent company helped SMIC to advance its fabrication processes.

    Huawei has not commented on the matter, and even state-ran Global Times does not explicitly say that the HiSilicon Kirin 9000S uses SMIC's 5nm-class process technology but prefers to call the information a rumor.


    The original article contains 574 words, the summary contains 148 words. Saved 74%. I'm a bot and I'm open source!

  • That's cool, so they are almost not 5 years behind everybody else, unless their 7nm node is actually like Intel's, ie. Bigger number but same density as the competition
