AI packaging push: how TSMC’s CoWoS advanced packaging is scaling for the next wave - AD HOC NEWS

TSMC's CoWoS (chip-on-wafer-on-substrate) advanced packaging technology is at the heart of the AI accelerator boom. As hyperscalers ramp up AI infrastructure investments, demand for CoWoS capacity has... Read original →

TSMC’s CoWoS capacity crunch signals a paradigm shift in AI hardware architecture. Technically, the tight integration of 2.5D silicon interposers and HBM stacks has become the critical path for AI accelerator performance, forcing EDA, test equipment, and materials suppliers to adapt to heterogeneous multi-die integration. Geopolitically, while the U.S. CHIPS Act incentivizes domestic advanced packaging, CoWoS remains deeply anchored in Taiwan, China’s precision manufacturing ecosystem—making near-term relocation impractical and heightening supply chain risk. Competitively, Samsung and Intel are pushing I-Cube and EMIB, but lag TSMC by over 18 months in yield and scale, unable to challenge its pricing power in high-end AI foundry. Over the next 24 months, CoWoS will evolve from a supporting process to a strategic system-level asset, reshaping TSMC’s revenue mix toward high-margin packaging and compelling customers into long-term capacity commitments—marking a decisive shift in semiconductor value from transistor scaling to system integration.
