IBM Debuts Sub-1 nm Chip

IBM has unveiled the world's first sub-1 nanometer chip technology, featuring a revolutionary 0.7 nm transistor architecture called 'nanostack'. This new design packs nearly 100 billion transistors onto a fingernail-sized chip, offering up to 50 percent more performance or 70 percent greater energy efficiency than IBM's 2 nm chips. The nanostack architecture, a three-dimensional, nanosheet-based design, allows for vertical stacking and staggering of transistors, optimizing performance and power efficiency. This innovation is projected to extend logic technology beyond the 1 nm node, advancing angstrom-level scaling and providing a roadmap for future semiconductor development for at least a decade. IBM is also forming Anderson, a quantum foundry, to further its leadership in quantum computing and semiconductor manufacturing, aiming for production of nanostack technology within the next five years.
