The node supports chiplet integration, allowing heterogeneous packaging for CPU-GPU-HBM stacks used in supercomputers.

Europe's AI Act emphasizes sustainable computing; 1.6nm's efficiency aligns perfectly, aiding compliance for DACH cloud providers.

Customer sampling begins mid-2026, with major platform wins already secured for 2028 products.

This positions TSMC ahead of Samsung and Intel in the race for sub-2nm dominance.

DACH firms gain from shortened lead times, crucial for just-in-time manufacturing in automotive sectors.

Supply Chain Implications for DACH Industries

Germany's semiconductor ecosystem relies heavily on TSMC for advanced nodes in power electronics and sensors.

1.6nm enables next-gen SiC and GaN integration, boosting EV efficiency for Volkswagen and Mercedes-Benz platforms.

Austria's AMS Osram benefits from compact image sensors on this node for automotive LiDAR.

Switzerland's STMicroelectronics can leverage for mixed-signal ICs in industrial automation.

TSMC's European expansion, including a potential Dresden fab, reduces latency and geopolitical risks.

Capacity allocation prioritizes strategic partners, ensuring DACH autosec firms secure allocations amid global shortages.

Cost per transistor drops 20-25%, democratizing advanced tech for mid-tier DACH SMEs.

Reshoring efforts like the EU Chips Act amplify these benefits, fostering local design wins.
