TSMC CoWoS shortage drives SK Hynix-Intel 2.5D push - digitimes

TSMC's CoWoS supply constraints are driving industry diversification efforts, particularly pushing SK Hynix and Intel toward collaborative advanced packaging initiatives. This development reflects the... Read original →

TSMC’s CoWoS bottleneck is catalyzing a strategic realignment in advanced packaging. SK Hynix and Intel’s joint push into 2.5D integration isn’t merely opportunistic—it’s a direct response to acute supply chain fragility in AI accelerators. This exposes systemic overreliance on a single foundry for critical interposer-based packaging, forcing logic and memory leaders to co-develop alternative heterogeneous integration flows. Technically, 2.5D stacking of HBM with CPUs/GPUs addresses bandwidth bottlenecks, yet fragmented standards in interposers, thermal management, and test protocols inflate R&D costs. Geopolitically, the U.S.-Korea tech alliance leverages this partnership to de-risk advanced packaging from Taiwan-centric capacity. NVIDIA, while currently shielded by allocation priority, may eventually need to diversify its packaging ecosystem. Samsung will aggressively pitch I-Cube as an alternative. Within 18 months, the industry will shift toward a dual-pole advanced packaging landscape—TSMC scaling CoWoS, while the Intel–SK Hynix axis emerges as a credible second source, redrawing power dynamics in AI hardware.
