Challenging to read things that are auto-translated from Chinese into English.
From what I gather from the article, didn't get the Nature paper yet, the novelty here is a bismuth deposition process that doesn't damage fine structures underneath it.
This is definitely one of the hard problems in semiconductor manufacturing and as stated, it is implied it allows for very fine lines (1 nm) for connecting elements on a chip. If they can do that in a commercial fab it would help with density, if they are really able to reduce connection resistance to "negligible amounts" then that would be really good for power dissipation.
- jacquesm 5y agoYes, exactly that. I'm much more happy about the potential for power savings than the possibility to further extend the miniaturization, the latter has a lot of other hurdles that need to be overcome than just in-the-lab process size. Spend enough money and you can already have features that small (and much smaller) in the lab, but the power saving potential here is massive.
