What happened
According to a TrendForce post dated Oct 20, 2026, AI packaging's supply crunch is spreading upstream, with supply bottlenecks hitting IC substrates. Taiwan's Unimicron warns that amid heating CoWoS and EMIB demand, lead times have stretched for over 80% of key equipment, with some reaching 30 months; meanwhile key materials face a potential 20% shortfall in 2027 (the shortfall is a potential forecast, not an achieved result).
