Huawei unveils new chip architecture, claims path to 1.4nm-equivalent processors by 2031

Huawei Technologies, the Chinese tech giant, has unveiled an innovative semiconductor scaling framework and chip architecture that aims to achieve processors equivalent to 1.4-nanometre technology by the year 2031. This announcement underscores Huawei's commitment to establishing a self-sufficient chip ecosystem in light of ongoing U.S. sanctions. The groundbreaking reveal occurred during the 2026 IEEE International Symposium on Circuits and Systems (ISCAS) in Shanghai, presented by He Tingbo, chair of Huawei’s Scientist Committee and head of the semiconductor business unit. Central to Huawei's ambitious roadmap is a novel principle known as the Tau Scaling Law. This approach moves away from the traditional reliance on transistor miniaturization dictated by Moore’s Law. Instead, it emphasizes “time scaling” to enhance chip performance and increase transistor density. He Tingbo noted that this framework has already been applied to 381 chips designed and mass-produced over the last six years. In addition, Huawei introduced its LogicFolding architecture, a new chip design strategy that aims to reduce resistance and capacitance during signal transmission. This development is expected to significantly boost chip efficiency and transistor density. The company has announced that its upcoming Kirin processors, set to launch later this year, will be the first commercial chips to incorporate this innovative architecture. He Tingbo expressed enthusiasm for the future, stating that before the end of 2026, the company anticipates delivering a significant breakthrough. He reflected on the progress made over the past six years in cultivating domestic semiconductor capabilities, including advancements in electronic design automation (EDA) tools and chip design methodologies, as China seeks to diminish its dependency on foreign technologies. Looking ahead, Huawei envisions substantial evolution of this architecture over the next decade, with plans to transition from local critical path folding to full-scale and multiplayer-folding for comprehensive optimization across devices and systems. He emphasized that from 2026 to 2035, extensive R&D efforts would lead to increased transistor density and operating frequency, enabling the company to consistently deliver cutting-edge mobile chips. Moreover, Huawei expressed strong confidence in its ambitions within the AI chip sector, positioning itself as a competitive force against global semiconductor players. According to He Tingbo, the performance of their new chips is poised to rival that of local competitors, particularly in delivering high-quality, low-latency large-scale AI solutions.
