Chip-on-Wafer-on-Substrate Capacity Becomes a Strategic Asset
TSMC's CoWoS packaging technology has become the single most sought-after manufacturing capability in the semiconductor industry, with customers reportedly committing capital years in advance to secure allocation for future accelerator generations. TSMC has disclosed multi-billion dollar capital expenditure specifically targeting CoWoS capacity expansion, citing sustained demand from AI accelerator customers outpacing even aggressive capacity growth plans. Samsung and Intel have both accelerated competing interposer packaging programs to capture overflow demand that TSMC capacity constraints leave unaddressed. The shift has turned packaging capacity itself into a strategic asset comparable to leading-edge wafer fabrication capability.
Market Impact: Adds 45% packaging content per chip
