TSMC CoWoS Bottleneck Pushes Intel EMIB Into AI Chip Packaging

The global shortage of advanced semiconductor packaging capacity is reshaping the supply chain for high-performance GPUs and AI accelerators. TSMC’s CoWoS technology remains the industry standard, but demand has outpaced production, forcing major chipmakers to diversify their manufacturing partners. This shift matters because it introduces new competition in the packaging sector and may alter the availability of next-generation graphics cards.

Intel and Taiwanese OSATs gain share as TSMC struggles to meet AI demand

TSMC currently operates five advanced packaging and test facilities in Taiwan and plans to build two additional fabs in Arizona to address the bottleneck. Despite these expansions, the company cannot meet the exploding demand for AI chips, which has led to orders spilling over to competitors. Intel and several Taiwanese OSATs, including ASE, SPIL, Powertech, and KYEC, are now receiving a larger share of these critical manufacturing contracts.

Intel is actively positioning itself to become the world’s second-largest player in advanced packaging by leveraging its EMIB technology. AMD is already utilizing CoWoS for its N2P process EPYC Venice processors and plans to use it for future MI400 and MI500 AI accelerators. Meanwhile, AMD is also evaluating Intel’s EMIB packaging as an alternative source for its own high-performance needs.

Reports indicate that NVIDIA may shift some of the packaging volume for its next-generation Feynman GPU to Intel to mitigate supply constraints. This potential move highlights the intense pressure on TSMC’s CoWoS capacity and the growing reliance on alternative advanced packaging solutions within the industry.

The diversification of advanced packaging orders away from TSMC signals a structural change in how GPU and AI chip manufacturers manage supply chain risks. Buyers and industry observers should monitor how Intel and other OSATs scale their EMIB and related technologies to meet this new demand.
