Chips are not getting cheaper.

Firm predicts it will cost $28 billion to build a 2nm fab and $30,000 per wafer, a 50 percent increase in chipmaking costs as complexity rises::As wafer fab tools are getting more expensive, so do fabs and, ultimately, chips. A new report claims that

    Afaik 2nm is the theoretical limit for current transistor tech so this sort of end-game for this type of tech.

      2nm process doesn’t actually mean 2nm though. Hasn’t in over a decade.

      The current 3nm process has a 48nm gate pitch and a 24nm metal pitch. The 2nm process will have a 45nm gate pitch and a 20nm metal pitch.

      “Nm” is just “generation” today. After 5nm was 3nm, next is 2nm, then 1nm. They’ll change the name after that even though they’re still nowhere near actual nm size.

        Intel already has plans to name the further generations xxA, after Angstroms

        Yeah I’m a bit curious what the marketing will be as they have to get more vertical, 3D. Will there be naming to reflect that or will they just follow existing naming, 0.5nm?

        The nm number is just the smallest part on the waffer. It’s not actually the transistor.

        This was my understanding as well: That beyond ~7nm the reliability begins to lose value because the diameter of an electron ‘orbit’ or whatever becomes a factor.

        Admittedly I’m not an expert. But my understanding was that to break this limitation and keep Moore’s law were kinda leaning into quantum computation to eventually fill the incoming void.

          The reason you mean is quantum tunneling. Essentially, at that small a scale an electron can ‘teleport’ outside of the system, which is obviously a big nono for computing.
