TSMC tackles the AI I/O wall with two COUPE bandwidth paths and deeper heterogeneous integration

TSMC's advancement in silicon photonics targets the growing bandwidth gap in AI computing, directly impacting upstream optical components, packaging materials, and testing equipment, while accelerating downstream data center and AI server upgrades. Geopolitically, Taiwan, China's strategic role in the global semiconductor supply chain intensifies, heightening tech decoupling risks between China and the US. Competitors like NVIDIA and AMD may accelerate in-house optical interconnect development to reduce reliance on TSMC. Over the next 12-24 months, co-packaged optics (CPO) will become a key battleground in AI chip design, signaling new technological barriers and market reshuffling.
