Intel (INTC) Targets Rio Rancho for World's First Glass Substrate Mass Production as AI Packaging Demand Surges

Intel (INTC) is advancing plans to transform its Rio Rancho, New Mexico facility into the first high-volume manufacturing site for glass-core substrates, a next-generation advanced packaging technology, as the company races to meet soaring demand from artificial intelligence chips. Glass substrates offer a flatter, more stable surface than traditional organic alternatives, enabling tighter chip-to-chip interconnects and higher packaging density. Earlier in 2026, Intel demonstrated its first “Glass Core” sample using its embedded multi-die interconnect bridge (EMIB) technology. Amkor's chief engineer has indicated the technology could reach commercialization within three years. The 218-acre Rio Rancho site, which began operations in 1980 and shifted to advanced packaging in 2021, is the most complete integrated packaging facility in the U.S. and has room for expansion. The plant is also already producing silicon photonics components for external clients, targeting data-center power and cost savings through optical interconnects. Intel currently operates only a glass-substrate pilot line at its Chandler, Arizona campus, making Rio Rancho the frontrunner for mass production.
