IBM unveils sub-1 nanometer chip with nearly 100 billion transistors (opens in new tab)

IBM is showing off a fingernail-size silicon chip that promises to deliver more power, more efficiently, in future computing, communications, and infrastructure deployments. The sub-1 nanometer (nm) chip features a transistor architecture at the 0.7 nm, or 7 angstrom node, IBM says. It packs nearly 100 billion transistors, which is almost twice the density of IBM’s 2 nm chip unveiled in 2021. A series of structural and material innovations made the chip possible, according to IBM, including i...
