Prohibited by the United States from purchasing EUV lithography machines that make modern chips, Huawei revealed the Tau Law and promises a Kirin 53% denser this fall using a technique that completely dispenses with the technology that China cannot i - CPG Click Petróleo e Gás

In response to U.S. restrictions preventing access to extreme ultraviolet (EUV) lithography machines, Huawei unveiled its 'Tau Law' framework at ICSAS 2026 in Shanghai. This innovation aims to enhance... Read original →

Huawei’s Tau Law represents a paradigm shift—replacing lithographic scaling with architectural ingenuity via Logic Folding and 3D stacking. This triggers cascading demands across the stack: EDA tools must evolve for vertical signal integrity, while domestic foundries like SMIC may fast-track hybrid bonding capabilities. Although it sidesteps ASML’s EUV dependency, secondary sanctions loom if U.S.-originated IP or design software remains embedded, compelling deeper decoupling. Competitors like TSMC and Samsung will likely accelerate their own 3D integration roadmaps (e.g., SoIC, X-Cube) to preserve density leadership, while Qualcomm and MediaTek face architectural disruption. Within 12–24 months, if Huawei scales this approach to AI and server chips, China could establish a viable 'EUV-free high-performance computing' pathway—forcing the industry to redefine what constitutes 'advanced node' beyond mere nm metrics.
