IBM unveils sub-1 nanometer chip technology

IBM unveiled what it describes as the world’s first sub-1 nanometer (nm) chip technology, introducing a transistor architecture at the 0.7 nm, or 7 angstrom node. The company positioned the advance as a significant step for semiconductor scaling as chipmakers confront the physical limits of traditional design approaches.

The new sub-1 nm chip packs nearly 100 billion transistors onto a fingernail-sized chip, with nearly twice the density of IBM’s 2 nm chip, unveiled in 2021. IBM said the progress is enabled by structural and material innovations, including a three-dimensional nanostack architecture designed to support further gains in performance and efficiency as chip features approach atomic dimensions.
