TSMC CoWoS shortage drives SK Hynix-Intel 2.5D push

TSMC’s CoWoS bottleneck is forcing a strategic realignment across the AI chip ecosystem. SK Hynix and Intel’s push into 2.5D packaging isn’t innovation for performance—it’s supply chain triage. Technically, this accelerates co-development of silicon interposers, thermal solutions, and EDA flows for heterogeneous integration. From a compliance angle, U.S.-Korea collaboration reduces exposure to export controls but raises barriers for smaller players lacking scale. Competitors like Samsung and ASE will fast-track FOPLP or X-Cube alternatives, while NVIDIA may be compelled to loosen its packaging specs to meet delivery targets. Within 18 months, advanced packaging will shift from back-end manufacturing to a core strategic asset—determining who defines next-gen AI accelerators. Diversification isn’t optional; it’s existential.
