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

IBM unveiled what it calls a “major semiconductor breakthrough” today, with the introduction of the world’s first sub-1 nanometer chip technology. The new chip “node”—a manufacturing process and its design rules—can pack 100 billion transistors onto a chip the size of a fingernail, nearly twice the density of IBM’s 2 nm node chip, which revolutionized the industry when it was unveiled in 2021. Achieving sub-nanometer scale has been a key industry milestone on the path to smaller, more powerful,
