Why TSMC’s CoWoS Role Keeps Taiwan Semiconductor (TSM) Central to the HBM-Driven AI Chip Boom

Taiwan Semiconductor Manufacturing Company Limited (NYSE:TSM) is one of the fastest-growing high-bandwidth memory stocks to buy. The company’s latest relevant financial update came on June 10, 2026, when it reported May revenue of NT$416.98 billion, up 30.1% year over year, while January-through-May revenue rose 30.0% to NT$1.96 trillion. The HBM link is not through memory production, but through TSMC’s advanced logic and packaging role in AI accelerators. Its CoWoS platform is designed for ultra-high-performance computing applications such as AI and supercomputing, and TSMC says CoWoS-S can integrate logic chiplets with HBM cubes over a silicon interposer.

That makes TSMC one of the central bottleneck suppliers for GPUs, custom AI chips, and other processors that need HBM close to the compute die. The latest revenue growth, therefore, fits the same demand cycle, pushing HBM adoption: larger AI models, denser accelerator clusters, and rising need for advanced packaging capacity rather than ordinary consumer-chip replacement.
