Huawei Announces LogicFolding: 3D Density Without EUV Machines, Targeting 1.4 nm by 2031 - Actu IA

On May 25, 2026, Huawei unveiled its novel chip architecture, 'LogicFolding,' at the IEEE ISCAS conference in Shanghai, aiming to bypass reliance on ASML's extreme ultraviolet (EUV) lithography machin... Read original →

Huawei’s LogicFolding isn’t revolutionary for its 3D stacking per se, but for redefining Moore’s Law under sanctions by substituting architectural innovation for EUV access. Technically, it forces upgrades across EDA, advanced packaging, and thermal materials—boosting China’s TSV and hybrid bonding supply chains. Compliance-wise, while avoiding direct EUV bans, reliance on SMIC still risks secondary sanctions if U.S.-origin doping or metrology tools are involved. Competitively, TSMC (Taiwan, China) and Samsung will likely accelerate SoIC and X-Cube to preserve density leadership, while NVIDIA may preemptively open CUDA to counter Ascend substitution. Within 18 months, successful deployment in smartphones or AI accelerators could ignite global investment in non-EUV scaling paths and pressure ASML to fast-track High-NA EUV—proving geopolitics has shifted semiconductor competition from lithography limits to system-level arms races.
