7 nm, 5 nm, 3 nm. The smaller MOSFETs and FinFETs become, the more circuits are possible on the same surface area. However, development is coming up against a very practical limit: the atomic radius.https://www.notebookcheck.net/Less-than-1-nm-New-technology-makes-tiny-chips-possible.863299.0.html
Interesting news, and I wonder how China is doing with its new factories and new technology?
All these advances are very good for cell phones, watches, etc... but we need them to consume less energy.
