ASE, Wus to jointly build Kaohsiung advanced packaging plant by 2029

ASE and Wus’s joint advanced packaging plant in Kaohsiung isn’t mere capacity expansion—it’s a vertical integration play targeting AI-driven packaging bottlenecks. This move will accelerate adoption of ABF substrates, hybrid bonding, and Chiplet interconnects, pressuring equipment vendors to slash lead times. Geopolitically, concentrating high-end packaging in southern Taiwan boosts efficiency but creates a critical single-point failure risk; any regional disruption could fracture the global HPC supply chain. ASE must now co-develop buffer inventory strategies with U.S. and European clients and secure alternate sources. Competitors like Amkor will likely fast-track Southeast Asian expansions, while JCET may leverage SMIC to push 2.5D/3D integration. Within 18 months, advanced packaging capacity will shift from a support function to a strategic asset—control over packaging nodes will dictate pricing power in AI compute delivery.
