Huawei unveils new scaling law and tech that narrows gap with TSMC, Samsung
Huawei introduced the Tau (τ) Scaling Law and LogicFolding architecture, claiming these innovations could achieve transistor performance equivalent to a 1.4nm process by 2031 without relying on advanced lithography tools. The breakthrough aims to reduce China’s dependence on US-sanctioned EUV machines for high-end chip production, marking a step toward self-reliance in semiconductor manufacturing.
Huawei Technologies unveiled a new scaling law and chip architecture designed to bypass the need for advanced lithography tools, a critical bottleneck in China’s semiconductor industry. The company’s Tau (τ) Scaling Law, presented by He Tingbo, chairwoman of the Huawei Scientist Committee and president of the semiconductor business department, outlines a principle for evolving semiconductors and electronic systems. According to Huawei, the new LogicFolding architecture reduces resistive and capacitive load, improving transistor density and enabling performance comparable to a 1.4nm process by 2031. The development comes as Chinese firms face US-led sanctions restricting access to extreme ultraviolet (EUV) lithography machines, essential for producing chips at 3nm and below. Huawei’s approach eliminates the reliance on these tools, offering an alternative path for high-end chip manufacturing. The company expects its self-developed chips to meet advanced performance benchmarks without traditional lithography advancements. He Tingbo emphasized the significance of the scaling law during a press briefing, stating it represents a foundational shift in semiconductor evolution. The LogicFolding architecture, a core component of this strategy, optimizes signal propagation and boosts transistor efficiency. This innovation aligns with broader efforts to strengthen China’s domestic semiconductor capabilities amid global supply chain constraints. The announcement underscores Huawei’s commitment to building a self-sufficient semiconductor ecosystem, reducing vulnerability to external restrictions. By leveraging the Tau Scaling Law and LogicFolding, the company aims to bridge the gap with leading manufacturers like TSMC and Samsung. The breakthrough could have far-reaching implications for China’s tech industry and global semiconductor competition.
