Intel is looking to broaden its foundry strategy beyond the race for advanced process nodes, placing greater emphasis on advanced packaging and glass substrate technologies as it positions Rio Rancho — its New Mexico site — as a global hub for next-generation packaging production.
According to Forbes and Wccftech, Intel's Rio Rancho facility has begun offering silicon photonics (SiPh) manufacturing services to external customers and could become the world's first site to mass-produce glass core substrates.
Sources familiar with the matter said the Rio Rancho site is expanding its equipment, workforce, and floor space, while offering customers services ranging from individual process steps to full end-to-end packaging solutions. The expansion reflects rapidly growing demand from external customers.
The push comes as demand for artificial intelligence (AI) chips, high-bandwidth memory (HBM), SiPh, and co-packaged optics (CPO) continues to gather pace. Intel is looking to use its packaging strengths to rebuild its strategic position in the global semiconductor supply chain.
Glass substrates take center stage
Glass substrates have become a growing focus in the semiconductor industry as AI chips and large-scale data centers require denser packaging. Traditional organic substrates are approaching their limits in warpage control, interconnect density, signal integrity, and power efficiency.
Intel first disclosed its glass substrate technology in 2023, unveiling a glass core solution combined with its Embedded Multi-die Interconnect Bridge (EMIB) packaging technology. Compared with conventional materials, glass substrates can reduce warpage, improve packaging density, and support faster signal transmission, making them a potential foundation for GPU, HBM, and CPO architectures.
Packaging closes the gap with process
As AI token usage and data center scale continue to grow, advanced packaging is rising in importance, moving closer to advanced process technology itself. Future competition in high-performance computing will depend not only on transistor scaling, but also on the ability to integrate compute dies, HBM, networking, and optical interconnects into a single package.
That shift is turning advanced packaging from the final stage of semiconductor manufacturing into a core technology that determines chip performance and power consumption.
Big names circle Intel's packaging play
Intel's advanced packaging capabilities have reportedly drawn interest from major technology companies, including Apple, Google, Microsoft, Nvidia, and Tesla. Amazon Web Services (AWS) and Cisco are already customers of Intel Foundry Services' (IFS) advanced packaging business. Intel has also established a strategic HBM partnership with SK Hynix and expanded its cooperation with outsourced assembly and testing provider Amkor Technology.
Analysts say Intel still trails TSMC and Samsung in advanced process technology, but remains competitive in packaging, where EMIB and Foveros 3D stacking are among its most differentiated assets. Some industry observers expect advanced packaging to become a profitable business for Intel Foundry Services sooner than advanced process manufacturing.
With its 14A process, glass substrates, SiPh, and CPO technologies advancing in parallel, Rio Rancho is emerging as a key site in Intel's attempt to regain relevance in the AI-era semiconductor industry. It could also become one of the company's most strategically valuable manufacturing assets.
