On July 6th, according to the 'Sci-tech Innovation Board Daily', sources familiar with the matter said that Huawei's Mate90 series, scheduled to be released this fall, will be equipped with a new Kirin chip based on the 'τ law' (Kirin 2026).
On May 25th this year, at the 2026 International Circuits and Systems Symposium, He Tingbo, a director of Huawei and president of its semiconductor business unit, announced the "Ta Law". This is the first time that a Chinese company has proposed new principles to drive industrial development in the global semiconductor industry.
On July 4th, Observer Network learned that according to the latest publication on the China Academy of Sciences' technology paper pre-release platform ChinaXiv, He Tingbo released the V2 version of "Time Compression Theory for Multi-Level Electronic Systems" (Tao Law) on July 3rd.
On May 25th, Huawei's He Tingbo delivered a keynote speech titled “Exploring and Practicing New Paths in Semiconductors”.
Compared to the V1 version released on May 25th, the new version adds a wealth of engineering details, real-world measurement data, and product evolution routes to the existing theoretical framework. This further improves the post-Moore era scaling theory system, with time constant τ as its core element.
In terms of the paper structure, the V2 version integrates the introductory paragraphs of the V1 version, resulting in a complete 8-chapter discussion system. The logic and technical layers within each chapter are more clearly defined. The new version of the paper also includes several schematic diagrams illustrating key technologies, such as the τ layered spacetime model, LogicFolding architecture, bonding interface cross-sections, Unified Bus interconnection architecture, and Hi-ONE light engine. This extends the concept of “time microsuction” beyond mere conceptual elaboration to a system-level technical presentation.
In recent years, Moore's Law has faced challenges from physical limits and economic benefits. The advantages brought by the reduction in transistor size have gradually diminished. Against this backdrop, Taolei proposes using time micro-minification instead of geometric minification, with the goal of systematically reducing the time constant τ. Through innovative technologies such as logic folding, the signal propagation delay is continuously reduced, further increasing transistor density and enhancing chip performance.
Several industry insiders also stated that the current constraints on lithography machines make it difficult to continue improving chip performance. When advanced manufacturing processes are limited, how to produce high-performance chips is the reason why Ta Law is a topic of concern.
According to He Tingbo, based on the Tao Law, Huawei has designed and mass-produced 381 chips, which are used in the mobile, AI, automotive, industrial, and infrastructure markets.
