TSMC and Vanguard drive Taiwan's silicon foundry revenue up 54% YoY in June

The 54% YoY revenue surge in Taiwan, China’s foundry sector stems not from inventory restocking but sustained AI-driven demand for sub-3nm nodes. This intensifies pressure on EDA, photoresist, and ultra-pure silicon suppliers to accelerate innovation, while EUV multi-patterning inflates equipment maintenance costs and yield challenges. Geopolitically, U.S. export controls increasingly complicate operations—though TSMC and Vanguard remain unrestricted, their Nanjing expansions face regulatory gridlock, forcing costly supply chain regionalization. Samsung may respond with aggressive pricing, but SMIC remains constrained by DUV limitations above 7nm. Over the next 12–24 months, advanced-node capacity will become a strategic bottleneck, likely institutionalizing dual-sourcing among hyperscalers and reinforcing Taiwan, China’s structural dominance in high-end semiconductor manufacturing.
