Summary
On November 11, 2024, TSMC suspended sub-7nm chip services to Chinese AI and GPU chipmakers following a US Commerce Department directive, as part of Washington's broader strategy to limit China's access to advanced semiconductor technology. The move creates supply chain disruptions and may shift orders to Samsung and SMIC, though both face their own export control constraints. This represents an escalation of US semiconductor export controls targeting AI-relevant compute infrastructure.
Key Points
- •US Commerce Department issued a directive requiring TSMC to halt sub-7nm chip exports to China starting November 11, 2024, targeting AI and GPU applications.
- •TSMC notified affected Chinese clients of the cessation, impacting companies focused on autonomous driving, cloud computing, and AI chip development.
- •Chinese firms are expected to shift orders to SMIC and Samsung, though Samsung also faces US export control restrictions due to its use of US-origin technology.
- •The directive builds on prior restrictions imposed on Nvidia and AMD, escalating Washington's effort to limit dual-use semiconductor technology access for China.
- •SMIC's technology and capacity limitations raise questions about whether Chinese domestic foundries can adequately substitute for TSMC's advanced process nodes.
