The smallest transistors currently in production are the intel 18A which have a gate length of 18 angstroms or 1.8nanometers.
However this is more of a naming convention than actual size as transistors have moved off planar design for a while now as FINFETS and GAA transistors became the norm.
The smallest planar transistors are around 22nm which would give you around 450,000 stacked end to end in one cm. This doesn’t take into consideration buffer devices or any proper layout procedure.
I however don’t think that’s the core breakthrough here. It’s more about it’s durability seemingly.
