IBM Develops First Sub-1 Nanometer Chip with Nanostack Architecture

IBM has announced a significant advancement in semiconductor technology with the creation of the world's first sub-1 nanometer chip, specifically 0.7nm. This breakthrough is enabled by a novel three-dimensional 'nanostack' transistor design. The new architecture is projected to offer substantial improvements, including up to 50% more performance or 70% greater energy efficiency compared to IBM's previous 2nm chips, with implications for AI and cloud computing.
