On July 3, 2026, He Tingbo, Director of Huawei and President of the Semiconductor Business Department, updated and released the V2 version of her authored paper, “A Time Scaling Theory for Multi-Layer Electronic Systems,” on ChinaXiv, the Chinese Academy of Sciences’ preprint platform for scientific papers. The updated version further improves the theoretical framework of post-Moore’s Law scaling centered on the time constant τ, systematically presenting engineering implementation pathways, measured quantitative data, and product evolution roadmaps. The paper also discloses parts of the roadmap planning for Huawei’s Kirin and Ascend chip series, demonstrating the practical transition of the “Tao (τ) Law” from a theoretical framework toward engineering validation. The V2 version of the paper highlights two major production-scale engineering validation achievements in mobile SoCs and AI systems. In the field of mobile SoCs, the paper introduces the “LogicFolding” technology, which enables significant improvements in transistor density and energy efficiency on fixed semiconductor process nodes. In the field of AI systems, through collaborative design technologies including Unified Bus, Hi-ONE, and 3D Folding, the level of hardware integration is expected to increase by more than 100 times by 2035. For more details about the paper, please visit the original publication on ChinaXiv: As an important national-level preprint communication infrastructure, ChinaXiv published and updated the “Tao (τ) Law” paper at the earliest opportunity, providing an important channel for the rapid dissemination of cutting-edge scientific achievements. Preprint platforms represent a key component of the emerging academic communication system in the era of open science. They play an important role in supporting the initial disclosure and attribution of research achievements, rapid dissemination, open discussion, and continuous improvement of scientific work. Since its launch in 2016, ChinaXiv has continuously focused on national strategic needs and directions of scientific and technological innovation. It has continuously enhanced its ability to support academic communication between the research and industrial communities, promoted more efficient and broader dissemination of China’s original scientific achievements, and provided strong support for building a more open, efficient, and trustworthy infrastructure for modern scholarly communication. |
