Will a panel-level or substrate-less advanced packaging line (CoPoS, CoWoP, or OSAT 310x310mm panel) reach announced mass production for an AI accelerator product by the end of 2027?

The CoWoS shortfall forces panelization and substrate-less relief paths into real mass production by end-2027, moving part of the AI package bottleneck out of TSMC's wafer-based lines.

Advanced packaging capacity limits supply

A CoWoS supply gap above 20% today and above 30% by 2027, plus AI packages exceeding wafer-format reticle and area limits, makes panel formats and CoWoP economically necessary. OSATs and TSMC qualify panel/substrate-less lines, cutting unit-area cost 20-30% and widening effective packaging supply beyond CoWoS allocation.

Panel-level lines stay off the mass-production roadmap

Suppliers cut or under-invested after the COVID cycle while AI demand accelerated past forecasts, so capacity remains scarce at critical points and headline capex is partly absorbed by price, duplicated sites and system coordination rather than new panel lines. Packaging allocation tightened early, with pools that xAI, Anthropic, OpenAI and Google all drew from since 2024, and a visible frontier win pressures competitors to spend on existing wafer-based packaging and infrastructure rather than unproven formats. This side would be confirmed if ASE, Powertech and TSMC all push panel-level mass production beyond 2028 in public statements.
