He, head of Huawei's secretive semiconductor business, reappeared after a 2019 hiatus. At a Shanghai symposium, she introduced the "Tau (τ) Scaling Law," which Huawei claims could reach 1.4nm transistor densities by 2031 without EUV lithography, challenging traditional scaling methods.
Huawei presents Tau Scaling Law, a new framework for chip development, focusing on reducing delays across devices and systems as Moore's Law weakens and US sanctions restrict access to advanced chipmaking tools.
Huawei introduced its revolutionary LogicFolding architecture and a new Kirin processor targeting 1.4 nm production. This innovation aims to overcome US sanctions by focusing on time-scaling instead of physical shrinking, with a new Kirin chip expected in Fall 2026 and a 1.4 nm equivalent density by 2031.
Huawei has been using a new scaling law, dubbed "Her's Law," to design and mass produce 381 chips over the past six years. The law replaces traditional geometric miniaturization with time scaling and enables the new LogicFolding architecture, boosting transistor density.
Huawei has introduced a new Tau (τ) Scaling Law and LogicFolding architecture, aiming to achieve chip transistor density equivalent to 1.4nm processes by 2031. This move is a significant step towards China's self-reliant semiconductor ecosystem, with new Kirin chips set to adopt the technology later this year.
