Huawei Introduces the Tau Scaling Law: Pursuing New Paths to Improve Chip Efficiency Through Advanced Packaging, 3D Stacking, and Logic Layering
At the end of May 2026, Huawei publicly explained its new chip concept, the “Tau Scaling Law” or “Tau Law,” emphasizing that it would no longer rely solely on continued transistor miniaturization, but instead improve chip density, performance, and efficiency through advanced packaging, 3D stacking, and LogicFolding. Reuters and The Wall Street Journal both confirmed this direction; related DIGITIMES coverage mentioned the role of glass substrates in this approach, although the main article did not directly expand on Huawei’s chip technology. Some details, such as whether glass substrates are central and the exact scope of industry impact, could not be fully confirmed from the available sources.
