Industry Analysis
The insatiable AI demand for HBM is forcing a full-stack semiconductor redesign: logic architectures now optimize around the memory wall, making advanced packaging and TSV the new bottlenecks. U.S. CHIPS Act incentives and EU V regulations compel Samsung and SK Hynix to build costly fabs abroad, inflating capex by 15–20%, while Taiwan, China and mainland China accelerate domestic DRAM ecosystems, deepening supply chain fragmentation. With 70% of output locked into AI, Samsung may prioritize in-house AI chip supply, whereas Micron leverages U.S. policy to cement defense and data center ties. Over the next 12–24 months, 'memflation' will drive adoption of HBM4-E and CoWoS-L hybrid integration, sustaining ETF inflows—yet a 2027 capacity surge risks sharp price corrections, creating a fragile 'high-inventory, low-elasticity' equilibrium.
