Intel Introduces Groundbreaking “Glass Core” Substrates with EMIB Advanced Packaging for Next-Gen AI Chip Development

Intel is making innovative strides in advanced packaging technology, particularly with its integration of glass substrates. This development highlights the company’s commitment and the potential for high-performance computing (HPC) applications.

Intel’s Glass Substrate and EMIB Technology: Paving the Way for Multi-Chiplet HPC Solutions

As discussions surrounding the future of advanced packaging evolve, the focus on glass substrates as a superior alternative to traditional organic materials grows stronger. At this year’s NEPCON Japan, Intel Foundry proudly unveiled its “Thick Core”glass substrate integrated with Embedded Multi-Die Interconnect Bridge (EMIB) technology, which they assert is uniquely suited for data center applications. Details about this cutting-edge implementation will reveal its potential benefits in the industry.

This announcement becomes even more significant considering prior speculation suggesting that Intel might abandon its glass substrate plans, particularly in light of employee departures. Historically, Intel has been a frontrunner in glass substrate technology, starting its initiatives before many of its competitors. This long-standing commitment makes the recent unveiling of their EMIB implementation all the more critical.

Intel’s latest advancement features a package with a 2x reticle size, measuring 78mm x 77mm. The design boasts an intricate vertical cross-section with a 10-2-10 stack-up architecture, comprising ten redistribution layers (RDLs), a two-layer glass core, and ten build-up layers. The unique properties of glass facilitate dense wiring, which is essential for modern computing demands. Notably, Intel has incorporated two EMIB bridges within the package, enabling connectivity between multiple compute dies.

The focus on the package’s footprint and the distinctive “No SeWaRe”designation indicate its intended use for server-grade products, including AI accelerators. This EMIB and glass substrate combination is essential for enhancing AI architectures by enabling finer connections, improved depth-of-field control, and diminished mechanical stress. Thus, integrating numerous chiplets within a single “super-package” becomes feasible with Intel’s innovative methodology.

The growing interest in EMIB from companies in the HPC sector is noteworthy, particularly given ongoing production challenges in the advanced packaging supply chain. Intel’s proactive stance suggests they are strategically positioning themselves to capture emerging opportunities in this space. If their momentum continues, advanced packaging could unlock significant new revenue streams for Intel Foundry.
