TSMC Nanjing · 台积电（南京）有限公司
Taiwan Semiconductor Manufacturing Company (TSMC) | Fab
TSMC’s only 12-inch (300mm) fab in mainland China, producing 16nm and other mature-node chips — reported to contribute roughly 2.4% of TSMC’s overall revenue per its 2024 annual report. Received a US annual export license (not individual per-shipment licenses) for chipmaking tool imports in early 2026, part of a broader shift from one-off vendor licensing to annual review for allied-country fabs operating in China.
Chinese name: 台积电（南京）有限公司 (Táijīdiàn (Nánjīng) Yǒuxiàn Gōngsī)
What does this facility make?
12-inch (300mm) wafers at 16nm and other mature process nodes — intentionally kept well behind TSMC’s leading-edge Taiwan/Arizona/Japan nodes.
Why does it matter?
The clearest example in this tracker of a foreign advanced-foundry leader operating a deliberately mature-node-only fab in China — TSMC has kept Nanjing’s technology multiple generations behind its frontier nodes elsewhere, widely read as a deliberate choice to maintain a China manufacturing presence without exposing leading-edge process technology to export-control or diversion risk.
