Interesting article on the history of microchip production. The evolution of manufacturing technology and how miniaturization is approaching the limits allowed by physics.

here is a small snip.... much more at the link

Tiny progress IBM says it can fit 50 billion transistors onto a chip the size of a fingernail using its latest 2nm chip technology. (Courtesy: IBM)

We are certainly not yet done with Moore's law. Although 2 nm is barely the width of 10 silicon atoms, remember the transistors in 2 nm chips aren't actually that small; the distance from one gate to another is nearer to 50 nm (the so-called 'gate pitch') so there is a bit more room to play with.

Yeah, 2nm (.002 um) is just the minimum structure that can be printed (generally a "line" or a space between lines). The actual transistors are generally larger.

My company wasn't on the bleeding edge, so I never had to deal with those. We were around .18 um (or 180 nm). We did a bit of foundry (TSMC) at .18 um. TSMC's technology is much closer to the bleeding edge than we were. I think they go down to at least .005 um.
