TSMC is using cross-node operations to leverage idle capacity at N7 while maintaining highly efficient operations at its N3/N5 fabs. Wafer shipments between Tainan and Taichung, along with the relocation of equipment from older Taiwanese fabs to Dresden, are moving forward.
Against the backdrop of the idle-fab problem created by the traditional business model, TSMC has formalized a method of using its highly efficient N3/N5 nodes to avoid bottlenecks at N7. It is seeking to address mismatches in assets arising from node transitions through coordination between fabs and optimized logistics.
In cross-node wafer shipments, wafers at leading-edge nodes are produced at full-capacity fabs such as N3, then semi-finished wafers are transported by truck to N7 in Taichung, where the metal layers are formed. The aim is to use idle capacity, ease bottlenecks, and maintain operations at N3/N5.
The logistics strategy goes beyond simple transportation. Equipment from older fabs in Taiwan is being repackaged and relocated to ESMC in Dresden. The emphasis is on accelerating the local launch through relocation while restraining capital investment and avoiding waits for new equipment orders.
This initiative could offer an alternative to conventional thinking on AI investment, suggesting that operational innovation can increase the flexibility of production capacity. The success of future relocations to Dresden and the durability of cross-node operations will be key points of focus.
