Industry Analysis
Imec’s XTCO paradigm marks a systemic countermove against post-Moore fragmentation. Technically, integrating silicon photonics into the die—not just the package—will force TSMC and Intel to accelerate optical-electrical co-design in CoWoS and Foveros, while redefining memory hierarchies via HBM4 and near-memory computing. On compliance, using High-NA EUV for qubit fabrication extends export controls into quantum hardware, further politicizing non-U.S. foundries’ access to advanced lithography. Strategically, NVIDIA may leverage chiplets plus photonics to bypass electrical I/O bottlenecks, while ASML cements its indispensability by anchoring quantum-classical hybrid manufacturing through imec. Within 18 months, R&D will invert: architectures will drive process choices, not vice versa. Companies fixated solely on transistor scaling will rapidly lose relevance in AI chips.
