TSMC expands advanced packaging capacity as AI demand strains the supply chain

DigiTimes reports that TSMC outlined rapid growth in CoWoS and SoIC capacity at its 2026 Technology Symposium. The company tied the expansion to AI demand and broader investment across advanced nodes, 3DFabric packaging, and smart manufacturing. For memory markets, CoWoS remains important because high-end AI accelerators often pair logic dies with HBM in advanced packages. More packaging capacity can help relieve a bottleneck that has constrained AI hardware shipments and influenced HBM allocation. This is not a direct HBM price quote, but it is a meaningful capacity signal. If packaging availability improves, it can support higher AI accelerator output and sustained pull for HBM supply.
