IBM claims world’s first sub-1 nanometer chip technology

IBM unveiled the world's first sub-1 nanometer chip technology at the 0.7 nm node, featuring a revolutionary "nanostack" transistor architecture . The chip packs nearly 100 billion transistors onto a chip the size of a fingernail, nearly twice the density of IBM's 2 nm chip unveiled in 2021 . The nanostack design vertically stacks and staggers transistors using 3D sequential integration while allowing different material combinations in each stacked layer to optimize performance and power efficiency .
