Does that have physical correspondence to anything? Smallest gap between units is 1.8-2nm?

- lbourdages 3y agoIt used to refer to the smallest feature they were able to print, not gate length. I don't even think it has a physical meaning anymore, hence why the fabs mostly dropped the nm suffix from their naming schemes.
- wmf 3y agoIt doesn't correspond to any physical size and hasn't for a while. The idea is that a sqrt(2) reduction in the marketing number is supposed to correspond to a significant increase in density and transistor performance.
- s3p 3y agoNot at all. It used to back when transistors were planar and their distance could be measured in nm, but now transistor gates are 3D and we're just lowering the number to what the equivalent performance might be if a theoretical transistor gate were that small.
