IBM creates world's first sub-1nm computer chip — cramming 100 billion transistors into a tiny fingernail-sized space

IBM's sub-1nm node chip.

For the first time, scientists can develop computer chips with transistors smaller than 1 nanometer. The new "NanoStack" architecture that has made this possible could even one day lead to transistors as small as 0.1 nm, the scientists claimed.

The new 0.7 nm transistors are significantly smaller than those that feature in standard 2 nm semiconductor chips used in supercomputers, AI systems and advanced graphics processing units (GPUs). While size designation doesn't necessarily correlate with an exact measurement of the transistors on the chips, it does represent their general capabilities.
