The fact that this level of precision can be achieved on 300mm wafers over many dozens of separate steps in separate devices is an insane achievement on its own.
> A city provides a useful analogy. When available land becomes scarce, urban planners initially reduce the spacing between buildings and use roads and open spaces more efficiently. Eventually, however, further horizontal expansion becomes impractical. At that point, the solution is to build upward. High-rise buildings create more usable space on the same piece of land by utilizing the vertical dimension. Really? som…
Retrofits are insanely expensive and often fraught with issues.

What you loose in heat you gain in speed caused by proximity. Perhaps this will allow for lower voltage and thus less heat.
Except hot spots quickly reach the melting point of silicon these days. That creates, let's say, a rather steep drop off in performance.
You must be thinking of something else

Yet everybody seems to think the moat is with the AI companies or nvidia.

This seems like it could accelerate the transition to sub-1nm nodes (previously projected to mid 2030s), maybe by the end of this decade.

Nope, thermodynamics is weird at small scales. Hot spots can absolutely reach 1400C if not designed not to. Sophie Wilson (initial architect of the ARM processor) has talked about how poorly designed silicon can reach point temperatures hotter than a nuclear reactor steady state.

That’s crazy. I thought maybe some of the other elements used in modern semiconductors might melt first. The wiring seems like a potential problem. But before that even the elements they use in the transistors themselves could be an issue.
