Answer: It is the dimension of Laser features on Wafer Lithography for semi's.

Once started really huge in the micron size , now state of the art is 5 nm with 2 nm runs going now with low yields for the fastest chips and 1 nm is possible but really hard.

Thank You Tony for your answer. I understood in a broader point of view. Could you answer in a specific manner for sub-180nm process meaning? Does it mean lower technology of 180nm or something else, I am confused in that perspective. Thank you.

It's just an expensive multi-billion $ evolution of Moore's Law for each change.
Lots of history.

Wikiwand - 180 nm process

The 180 nm process is a MOSFET semiconductor process technology that was commercialized around the 1998–2000 timeframe by leading semiconductor companies, starting with TSMC and Fujitsu, then followed by Sony, Toshiba, Intel, AMD, Texas Instruments and IBM.
