Intel is rapidly working on its advanced packaging capabilities and is reportedly partnering with AU Optronics, a Taiwanese optoelectronics giant, for co-packaged optics and massively integrated chips. The collaboration combines Intel's advanced packaging experience with AUO's Micro LED substrate specialty. Intel will fully enter the field of Micro LED substrates, a specialty of the Taiwanese manufacturer, and the two will jointly develop CPO and high-density chip layouts with advanced integrated solutions.

CPO, co-packaged optics, integrates optical components with the silicon, which matters for AI and compute demands that are swelling. Intel's experience with glass substrates and advanced packaging solutions such as EMIB makes sense for AUO to join. Intel has recently obtained a US patent involving the packaging of ICs on Micro LED substrates, which discusses embedding portions of the semiconductor chip within a glass substrate containing TGVs, Through-Glass-Vias, as opposed to TSVs, Through-Silicon-Vias. The TGV is the interconnect choice: glass-based vias instead of silicon-based ones, which is the technical core of the collaboration.

This is Intel pushing into the optics-and-packaging frontier. The slowdown of Moore's Law makes advanced packaging a necessity, and CPO is the specific target: integrating optics with the chip to handle the bandwidth demands of AI. The Micro LED substrate is the substrate choice, and the TGV is the interconnect. Intel's EMIB series of technologies is the existing packaging base, and the Micro LED and glass-substrate work is the extension. The collaboration with AUO brings the Micro LED substrate expertise into Intel's packaging stack.

The timeline for the CPO products, the specific chip layouts, and whether the patent translates to shipping products. Intel declined to comment on the reports, and AUO's chairman has previously said the company entered advanced packaging and glass substrates, but the collaboration's product timeline is not stated. The patent is the technical signal, not a product commitment.

Whether Intel and AUO announce CPO products, whether the Micro LED substrate work reaches production, and whether the TGV interconnect scales. For the packaging industry, Intel entering Micro LED substrates and CPO is a significant move into the optics-and-packaging frontier, and the AUO collaboration is the signal that the work is a joint effort rather than a solo push. The TGV is the interconnect choice: glass-based vias instead of silicon-based ones, which is the technical core of the collaboration, and the Micro LED substrate is the substrate choice that AUO brings into Intel's packaging stack.

Intel and AU Optronics are combining advanced packaging for CPO and Micro LED substrates, with TGVs as the interconnect. A push into the optics-and-packaging frontier as Moore's Law slows.
