I didn’t think the ~5nm limit could be broke due to quantum tunneling.

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

They solved this problem by making the nanometer bigger.

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.

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.

Depending on how in-depth you want to delve into this.
Newsletter semianalysis.com
Youtube Asianometry
Some litography university textbooks. Sadly I don’t know which ones.

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. Epwill there be naming to reflect that or will they just follow existing naming, 0.5nm?
