We are going to hit an interesting spot in a few years when the processes run out of numbers to use - because the “x nm process” hasn’t been talking about the actual sizes for almost three decades (the 250nm process back in 1997 was one of the last ones).
The “2nm” process for example has a gate pitch of 45nm, and metal pitch of 20nm. Once they go below 42 and 16 - 1nm values - is it going to be the 0nm process? And -1nm after that?

Both Intel and TSMC have leveraged A (for Angstrom), as in 18A node, for their next generation nodes.
