Up until 45nm the name of a process node was twice the length of a transistor's gate. At that point it stopped being technologically feasible to reduce the gate length but companies were able to find other ways, such as fin FETs, to pack ever more transistors in with each node without having to reduce the transistor length.
- kayson 4y agoThis is not correct. First, process node names were the same as the minimum transistor gate length, not 2X. Second, at least down to 28nm, this relationship held true. It may have also been the case for 22nm. It all went out the window with finfet processes.
