180nm denotes which one Poly width or min diffusion width ?

[cnnprem.eee]

In 180nm technology Here 180nm denotes min diffusion width or poly width?

Please any body help

Usually it's a channel length, i.e. Poly width.

Technology node (180nm, 130nm, 90nm, 65nm, 45nm, 32nm, 22nm, etc.) is defined as the lowest metal (metal 1) half-pitch (i.e. metal width or metal spacing) for the DRAM version of the process.

Gate length or channel length is usually much smaller than the process node dimension (for example, in 90nm technology, the gate length is about 70nm).

Which one is correct lower metal half pitch or poly width?
do u have any manual please send it to me
