Huawei's top semiconductor scientist Liao Heng said in a rare interview that Western chipmakers including Nvidia will eventually hit physical boundaries. He discussed Huawei's Tau Scaling Law as an alternative approach to chip advancement.
Liao Heng, a leading figure in Huawei's chip development, warned that conventional chipmaking strategies employed by Western companies are approaching fundamental physical constraints. The comments come as the semiconductor industry grapples with slowing progress in transistor miniaturization, the traditional path to performance gains.
Huawei has proposed its Tau Scaling Law as a framework for continued chip improvement beyond traditional scaling limitations. The approach suggests alternative methods for enhancing processor capabilities without relying solely on shrinking transistor sizes.
The remarks underscore growing divergence in semiconductor strategy amid U.S. export controls on advanced chip technology to China. While Western companies focus on established scaling techniques, Huawei is exploring different architectural and engineering paths to maintain competitiveness in processor design.
Liao's comments reflect broader industry recognition that Moore's Law—the decades-long trend of doubling transistors on chips—faces inevitable physical and economic challenges at nanometer scales.
