U.S.-made chips still require shipment to Taiwan for packaging, undermining domestic manufacturing goals

Nvidia has quietly cornered the market on one of the semiconductor industry’s most critical—and least understood—bottlenecks. The AI chipmaker has reserved the majority of TSMC’s most advanced packaging capacity, creating a new supply constraint that could throttle the entire AI industry’s growth. Even chips fabricated in new U.S. fabs must make a 12,000-mile round trip to Taiwan for final assembly, exposing a vulnerability in America’s semiconductor independence push.
The semiconductor industry’s attention has fixated on fabrication—the intricate process of etching transistors onto silicon wafers. But Nvidia’s latest strategic move reveals that advanced packaging, the lesser-known final assembly step, is emerging as the real constraint on AI chip production.
Nvidia has effectively monopolized TSMC’s most sophisticated packaging services, particularly CoWoS (Chip-on-Wafer-on-Substrate) technology that’s essential for high-performance AI accelerators. This packaging method allows multiple chiplets to be stacked and interconnected with extreme precision, creating the dense configurations required for training large language models and running inference at scale.
The implications extend far beyond corporate rivalry. Even as the U.S. pours billions into domestic chip manufacturing through the CHIPS Act, American-made semiconductors still need to travel to Taiwan for advanced packaging. TSMC dominates this specialized capability, operating the world’s most advanced packaging facilities almost exclusively in Taiwan. The geographic concentration creates exactly the kind of supply chain vulnerability that Washington’s semiconductor strategy aimed to eliminate.
Intel, which is racing to catch up in both fabrication and packaging technology, finds itself in a particularly awkward position. The company’s ambitious plans to become a foundry competitor to TSMC hinge partly on developing its own advanced packaging capabilities. But current production realities mean even must sometimes rely on for packaging services—capacity that has largely locked down.
