Panel-level / glass-substrate packaging
Next-gen advanced packaging beyond wafer-scale CoWoS
To break the CoWoS bottleneck, the industry is racing to panel-level packaging and glass-core substrates (Intel, Samsung, Absolics/SKC, LG) that promise larger, cheaper interposers for giant AI accelerators. This is the leading-edge frontier of the packaging chokepoint that CoWoS/SoIC currently gate.
