IMAPS Symposium 2025: Chiplets vs. Dielets and the Truth about Co-Packaged Optics
Description
We sit down with Dr. Subu Iyer of UCLA to unpack chiplets vs dielets, why a universal ecosystem is missing, and how sub‑10 µm bump pitch could make protocols optional. Then we host a panel featuring John Knickerbocker, IBM; Mike Kelly, Amkor; and Tolga Tekin, Fraunhofer IZM on co‑packaged optics, bandwidth, and power for AI data centers.
• chiplet as design construct, dielet as physical die
• lack of universal chiplet ecosystem and interoperability
• bump pitch scaling and protocol overhead trade‑offs
• packaging purpose reframed as power, communication, and cooling
• economic shift and value capture in advanced packaging
• national competitiveness, prototyping access, and talent pipeline
• co‑packaged optics definition, drivers, and cost targets
• copper reach limits, latency, and bandwidth density for AI
• hyperscalers as early adopters and five‑year outlook
