Huawei introduced the Tau (τ) Scaling Law as an alternative to Moore’s Law at the IEEE International Symposium on Circuits and Systems in Shanghai. The company aims to achieve transistor density equivalent to a 1.4nm process. It expects to reach this milestone by 2031. This strategy seeks to build a self-reliant semiconductor ecosystem following US sanctions on advanced chipmaking equipment.
The Tau Scaling Law shifts focus to time scaling, prioritizing signal travel speed over traditional geometric shrinking. Huawei will utilize LogicFolding architecture to optimize circuit layouts and increase performance. The upcoming Kirin chips scheduled for release in Fall 2026 will be the first to feature this architecture.
