New Delhi, June 26 -- IBM has unveiled what it says is the world's first sub-1 nanometer (nm) chip technology, introducing a new transistor architecture that the company believes could extend semiconductor scaling for at least another decade.

The new semiconductor technology features a 0.7 nm (7 angstrom) process node and nearly 100 billion transistors on a chip roughly the size of a fingernail, which is almost double the transistor density of IBM's 2 nm chip unveiled in 2021.

According to IBM, the breakthrough is enabled by a new three-dimensional transistor architecture called Nanostack, designed to overcome the physical limitations of conventional chip scaling while improving computing performance and power efficiency.
