Huawei Claims 1.5-Micron Hybrid Bonding for 2026 Kirin Chips, Ahead of TSMC and Intel
Huawei's 2026 Kirin smartphone chips will feature 1.5-micron bond-pitch 3D stacking in a hybrid-bonding architecture, according to SemiAnalysis, far tighter than TSMC's 6-micron SoIC and Intel's 9-micron Foveros Direct. SemiAnalysis said the tighter pitch yields 16 to 36 times denser interconnect, enabling Huawei's LogicFolding design to split logic more granularly across stacked dies and shorten critical paths.
The packaging detail adds specificity to Huawei's broader Tau Scaling strategy, which the company has described as improving chip performance by reducing signal delay rather than relying mainly on smaller transistors after U.S. export controls cut off normal access to TSMC in 2020. Huawei has said its next Kirin phone chip will be the first full test of Tau Scaling, while SemiAnalysis said the following generation could move to a 1-micron bond pitch; a separate industry comment suggested part of any edge may depend on electronic-design tools built for 3D layouts rather than planar chips.

@teortaxestexSo Huawei is going for stacked small dies with Cerebras-style redundancy. It is, indeed, very clever if designed well. At the same error rate, they can go from like 20% to 70%+ wafer utilization. By EOY 2026, SMIC should have 100K WPM at 7n

@teortaxestex> 16-36x denser interconnect enables Huawei's LogicFolding design if real, this is a purely EDA software advantage, right? As the Chinese doomers correctly point out, with better lithography you can reduce bond pitch as well. But Western
