DIGITIMES Insight: AI chip upgrades shift substrate supply bottleneck from upstream materials to equipment

DIGITIMESSeptember 20, 2026en

DIGITIMES Intelligence has observed that as the performance of AI accelerators and server CPUs continues to advance, chips are increasing not only in compute core counts and I/O channels but also in integration complexity. Higher integration of high-bandwidth memory (HBM), high-speed SerDes, and chiplet designs makes signal transmission, power delivery, and component interconnects within the package far more complex, driving high-end IC substrates toward larger surface areas and higher layer counts.
