What This Article Covers

1.Huawei's semiconductor division head, He Tingbo, announced the development of the 'Tau Scaling Law' (Her's Law), a new chip design principle that optimizes for communication time rather than transistor density.

2.The company aims to use this method to produce 1.4-nanometer (nm) chips by 2031, potentially sidestepping the need for extreme ultraviolet lithography (EUV) machines restricted by US sanctions.

3.This development is a direct response to US sanctions imposed since 2019, which have cut Huawei's access to advanced lithography equipment, and is central to the strategic competition in AI and semiconductor technology between the US and China.

The Big Picture
