2.5D packaging - organic/bridge interposer (CoWoS-L, EMIB)

Supply is constrained by embedded bridge die shortages and organic substrate capacity, and a qualified second source is years away.

2.5D integration using organic or embedded silicon-bridge interposer instead of full silicon interposer. Lower cost than CoWoS-S for applicable AI GPU designs; adopted for next-gen products from 2025. Constrained by embedded bridge die supply and organic substrate capacity.

What the evidence shows

Production of the carrier and the CoWoS assembly runs captive at TSMC — there is no merchant market.
