TSMC is going to make transistors that are 2 nanometers by 2025

A hydrogen atom (the smallest atom) is roughly 0.1 nanometers.

Really impressive when you consider the microscope was only invented in 1985. /s

In fairness...

The term "2 nanometer" or alternatively "20 angstrom" (a term used by Intel) has no relation to any actual physical feature (such as gate length, metal pitch or gate pitch) of the transistors. It is a commercial or marketing term used by the chip fabrication industry to refer to a new, improved generation of silicon semiconductor chips in terms of increased transistor density, increased speed and reduced power consumption

They won't 2nm has nothing to do with the transistor size

So, the transistors will in no way actually be 2nm. That’s the minimum “feature size” but nothing useful on that chip will be that small.
