The direct catalyst for this comprehensive outbreak in the chip sector was Huawei's official announcement at the 2026 International Circuits and Systems Symposium held in Shanghai that morning.“Tao (τ) Law”. He Tingbo, Director of Huawei and President of the Semiconductor Business Department, officially announced this law in a keynote speech entitled “Exploration and Practice of New Paths for Semiconductors”. This isFor the first time in the global semiconductor field, China has proposed new principles to guide industrial development.

“Tao's Law” constructs a system that runs through devices, circuits, chips and system levels.Multi-level collaborative optimization system. He Tingbo revealed that based on this law, Huawei381 chips have been successfully designed and mass-produced in the past six yearswidely covering mobile phones, servers, communications and other fields. The Kirin mobile phone chip, which will be released in the autumn of 2026, will be the first to fully adopt logic folding technology, and its performance is expected to achieve a step improvement. Huawei expects to2031the transistor density of high-end chips based on this law will reachThe same level as the 1.4nm process.

The release of Tao's Law has greatly boosted market expectations for the development of the entire domestic semiconductor industry chain. This law reduces the sole reliance on extreme line width shrinkage through architectural innovation and system-level optimization paths, and provides a new development paradigm for the domestic wafer foundry link. Galaxy Securities has previously pointed out that SMIC's advanced process yield and production capacity continue to climb, and the overall utilization rate remains high. There may be valuable revaluation opportunities in the future.
