Taiwan's TSMC, the world's largest foundry (contract semiconductor manufacturer), plans to begin mass production of 1.4-nanometer (nanometer, one-billionth of a meter) process semiconductors in 2028, Taiwanese media including the China Times reported on the 20th.

I don't think they are anywhere near 1nm in terms of semiconductor feature size:

Wikipedia seems to imply that that 1 nm class fabrication processes will have a 16 nm metal pitch:

Don't get me wrong, it's mind boggling that we operate on such scales and that semiconductors that use these leading edge processes are somewhat accessible (even with the massive increase in price due to data centre demand). But we're not anywhere near actual 1nm features.
