Huawei Announces New Semiconductor Law, Claims Mass Production of 381 Chip Models

Central News Agency, Beijing, May 25. Chinese telecommunications giant Huawei officially announced the 'Tau (τ) Law' today, stating that it has designed and mass-produced 381 chip models based on this principle over the past six years. This autumn, Huawei will release a new Kirin smartphone chip that fully adopts logic folding technology. According to the People's Daily, Huawei board member and President of the Semiconductor Business Unit, He Tingbo, announced the 'Tau Law' during a keynote speech at the 2026 International Symposium on Circuits and Systems in Shanghai. In recent years, Moore's Law in semiconductors has faced physical limits, with 'geometric scaling' of transistors slowing down. The 'Tau Law' proposes replacing 'geometric scaling' with 'temporal scaling,' aiming to systematically reduce the time constant (τ). By using innovative technologies like logic folding, it compresses signal propagation delays, continuously increases transistor density, and enables the evolution of semiconductors and electronic systems. Reports state this is the first new principle for industrial development proposed by China in the global semiconductor field. The 'Tau Law' builds a multi-level collaborative optimization system spanning devices, circuits, chips, and systems. By 2031, the transistor density of high-end chips based on this law is expected to reach the equivalent level of a 1.4nm process.
