打破内存墙瓶颈，HBM已成为DRAM市场增长主要驱动力。HBM解决带宽瓶颈、功耗过高以及容量限制等问题，已成为当下AI芯片的主流选择。Yole预计全球HBM市场规模将从2024年的170亿美元增长至2030年的980亿美元，CAGR达33%。SK海力士指出，HBM的引入不仅能显著提升AI的性能和质量，其增长速度甚至超越了传统内存性能，有效打破了内存墙瓶颈。
民生证券认为，从产业链来看，HBM产业上游主要包括电镀液、前驱体、IC载板等半导体原材料及TSV设备、检测设备等半导体设备供应商；中游为HBM生产，下游应用领域包括人工智能、数据中心以及高性能计算等。在HBM制造中，TSV工序是主要难点，其涉及光刻、涂胶、刻蚀等复杂工艺，是价值量最高的环节。国产HBM量产势在必行，当前国产HBM或处于发展早期，上游设备材料或迎来扩产机遇。
