Industry Analysis
The surge in 3D IC technology stems not from incremental innovation but from AI and HPC’s insatiable demand for bandwidth and power efficiency. TSMC (Taiwan, China) has established a formidable lead with CoWoS and 3DFabric, compelling Samsung to accelerate hybrid bonding scale-up, while ASE bets on chiplet ecosystems to offset process node gaps. Technologically, TSVs and hybrid bonding are reshaping EDA, test equipment, and materials supply chains—especially demanding breakthroughs in alignment precision and thermal management. Geopolitically, U.S. and EU subsidies for advanced packaging come with tightened export controls, inflating compliance costs. Over the next 12–24 months, the race for HBM4 and 3D-stacked DRAM will intensify, yet yield volatility and slow capacity ramp could trigger AI chip delivery bottlenecks. The ultimate winners will be platform-scale players integrating design, fabrication, and packaging capabilities.
