4. Huawei Kirin 2026 transistor density increases 55%; He Tingbo publishes paper on the Tao (τ) law Community
IT Home reported on September 4 that Huawei engineer He Tingbo published a preprint paper on ChinaXiv titled “Should the Huawei τ (Tao) chip have burned up from overheating?” disclosing the underlying principles of the τ (Tao) law and releasing measured data for the Kirin 2026 chip. The paper shows that the Kirin 2026’s transistor density is 55% higher than its predecessor. The paper states that the industry generally believes 3D stacking causes severe heat issues, but the measured results of the Kirin 2026 offer a different answer.
Traditional Moore’s law relies on shrinking transistor geometry to achieve performance iteration. Huawei instead chose to compress the characteristic delay τ of signal transmission inside the chip, with the core implementation technology being LogicFolding. This technology relies on 3D hybrid bonding, splitting the originally flat circuits into multiple vertically stacked silicon dies, bridging each layer with micron-scale vertical interconnects, replacing horizontal wiring with extremely short vertical jumps. The Kirin 2026 achieves a 1.5μm bonding pitch with 50 million vertical interconnects; the next-generation Kirin 2027 has already reached a 1μm bonding pitch.
