Intel

Who Intel is

Intel needs no introduction as a chipmaker, but its role in this particular value chain is less well known: its ATTD (Assembly and Test Technology Development) team has been researching glass substrates internally since 2014 — over a decade of quiet R&D before the rest of the industry even had a public conversation about the material. That head start is arguably Intel's single biggest asset in this chain.

What Intel does

Intel shows up twice in this value chain, and the distinction matters. First, as a packaging and assembly player: it publicly announced glass substrate plans at its Innovation Day in September 2023, targeting mass production sometime between 2026 and 2030, and in January 2026 demonstrated the first working glass-core package at NEPCON Japan — a 78×77mm package combining Intel's EMIB packaging technology with a "10-2-10" glass core structure (10 redistribution layers, a 2-layer glass core, then 10 more redistribution layers, 22 layers total, at a 45µm bump pitch). Intel also reported achieving "No SeWaRe" — no micro-cracking — in its testing, a meaningful yield milestone for a material the whole industry has struggled to drill and handle without fracturing.

Second, as AI demand: Intel's own AI and HPC chip roadmap is one of the reasons glass substrates need to exist at all, since its accelerator packages have grown large enough that organic substrates can no longer hold them flat.

How Intel makes money

Intel's core business is designing and manufacturing its own chips, and glass substrates are, first and foremost, an internal manufacturing capability meant to keep Intel's own next-generation AI and HPC packages viable. The bigger opportunity — and the bigger open question — is whether Intel's packaging technology (through its foundry services business) becomes something outside chipmakers pay Intel to use, turning over a decade of internal R&D into an external revenue line rather than just a defensive necessity.

Where Intel sits in the value chain

The bigger trend for Intel

Intel's glass-substrate work sits inside its broader, higher-stakes turnaround story — a company trying to prove its manufacturing and packaging technology can still lead the industry rather than follow it, at exactly the moment AI demand is reshaping which chipmakers matter most. A credible, working glass-substrate lead is one of the few places Intel can point to a genuine multi-year head start over competitors like TSMC and Samsung, both of whom are running their own glass-packaging qualification in parallel but reportedly starting later.
