Any indication of the technical process without quotes for "2nm", etc. is a deception of readers, the public and clearly imposed commercial advertising. Any person who understands physics and at least minimally how modern chips are created knows perfectly well that all these names including nanometers without quotes are a blatant marketing lie for the stupid majority of the population.
In fact, Intel has at least stopped indicating nm in the name of its technical processes (but not in marketing presentations to the public), which is much more honest than what TSMC and others write.
All this speaks only of one thing - about the further technical and scientific degradation of the education of the majority of the planet's population relative to even the old knowledge of 50-70 years ago, not to mention new layers in science...
