"The term "3 nanometer" has no relation to any actual physical feature (such as gate length, metal pitch or gate pitch) of the transistors. According to the projections contained in the 2021 update of the International Roadmap for Devices and Systems published by IEEE Standards Association Industry Connection, a 3 nm node is expected to have a contacted gate pitch of 48 nanometers and a tightest metal pitch of 24 nanometers"

- PrayagBhakar 3y agoWhy is it called 3nm then?
- fsociety 3y agoIt is defined by the smallest physical feature on the transistor - regardless of what that feature is. It used to be defined by the size of gate iirc - that is why people say it has no relation to the physical features.
- sim7c00 3y agosuper interesting info thanks. i was still on the gate size club :/
