【#Tech24H】IBM has unveiled a major semiconductor breakthrough with the world's first sub-1-nanometer chip technology, featuring a revolutionary transistor architecture at the 0.7-nanometer (7 angstrom) process node. IBM states that its latest sub-1nm chip integrates nearly 100 billion transistors on a chip the size of a fingernail, achieving a density nearly twice that of IBM's 2nm chip released in 2021. This technology is enabled by a series of structural and material innovations, including IBM's groundbreaking three-dimensional nano-stack architecture, demonstrating that continued performance and efficiency improvements remain possible even as chip features approach atomic dimensions. According to published technical results, the new chip is expected to deliver a substantial performance leap—up to 50% performance improvement and 70% greater energy efficiency compared to IBM's 2nm node chip—significantly boosting computing power for applications ranging from generative AI and cloud infrastructure to next-generation electronic devices.
