IBM has unveiled chip technology that could help extend Moore’s Law another decade

IBM has announced a prototype chip using a new 'nanostack' architecture that vertically stacks two layers of transistors on a single silicon chip, achieving roughly 100 billion transistors on a fingernail-sized area — double the density of its 2021 state-of-the-art. The design, classified as a complementary field-effect transistor (CFET), promises up to 50% more performance and 70% better energy efficiency compared to IBM's previous generation. IBM distinguishes its approach by staggering the second transistor layer rather than stacking directly on top, simplifying wiring and improving alignment precision. Key manufacturing challenges remain, including thermal budget constraints (keeping processes below 400°C) and higher defect rates from multi-layer fabrication. IBM plans to partner with semiconductor manufacturers to bring the technology to GPUs, CPUs, and data center chips within a decade, potentially extending Moore's Law by 10–15 years.
