The term "3 nanometer" has по direct 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 IEEE Standards Association Industry
Connection, a 3 node is expected to have a
contacted gate pitch of 48 nanometers, and a
tightest metal pitch of 24 nanometers.!"2!
However, in real world commercial practice, 3 is
used primarily as a marketing term individual
microchip manufacturers (foundries) to refer to a
