Advanced Packaging Co-Packaged Optics Foundry Diversification

Leading-edge artificial intelligence silicon requires complex heterogeneous chiplet packaging. Researching advanced packaging co-packaged optics foundry diversification reveals the extreme concentration of TSMC's Chip-on-Wafer-on-Substrate (CoWoS) and emerging Silicon Photonics (CPO) lines.

Diversifying frontend fab capacity to the US or Europe cannot overcome semiconductor supply bottlenecks unless backend advanced packaging capacity is equally geographically distributed.

Advanced Packaging Geographic Concentration

Over 85% of global high-end heterogeneous AI chiplet packaging remains located within a concentrated geographic zone in Western Taiwan.

Frequently Asked Questions

Why is backend packaging as critical as frontend wafer fabrication?

Modern AI accelerators cannot function without advanced packaging substrates that link High-Bandwidth Memory (HBM) with logic dies at microscopic interconnect pitches.
