## Summary

AI packaging has hit an organic-substrate wall: resin cores warp and crack under ever-larger multi-die [HBM](/pt/n/micron-q3-2026-record-hbm)-heavy accelerators, and the industry is pivoting to **[glass cores](/pt/entity/glass-substrate)**. In January 2026 [Intel](/pt/entity/intel) showed EMIB-plus-glass samples (crack-free) at NEPCON Japan; [Samsung](/pt/entity/samsung) (via SEMCO) ran a Sejong pilot line and is sampling US cloud providers; and SK Hynix subsidiary **[Absolics](/pt/entity/absolics)** became the first in the world to ship **commercial-grade** glass panels from Covington, Georgia, targeting AMD and Amazon, expecting ~$100M first-year revenue. On 15 April [Korea](/pt/entity/south-korea) moved to **contest Intel on glass-substrate standards**, a fight to set the rules of the next packaging generation. Glass cuts signal-transmission power ~50% and improves signal integrity ~40% versus organic.

## By the numbers

- ~50%, reduction in signal-transmission power vs organic substrates.
- ~40%, improvement in signal integrity (Absolics test data).
- ~$100M, Absolics' expected first-year glass-substrate revenue.
- 4,000 → 8,000, Absolics panels/month, planned 2026 capacity doubling.
- 2027, Samsung's targeted glass mass-production start.

## Why it matters

Advanced packaging, not transistor scaling, increasingly gates AI accelerator performance. Glass substrates are the material unlock for bigger, denser GPU+HBM packages, and the supply chain is shifting east: SK's Absolics has the merchant lead, Samsung the volume runway, Intel the integrated play. Whoever sets the glass standard shapes who supplies the next decade's AI silicon.

## What to watch

- The Intel-vs-Korea standards contest and which spec wins merchant adoption.
- Absolics yield and ramp from 4,000 to 8,000 panels/month.
- Whether glass appears in shipping flagship AI accelerators (AMD, Nvidia) and when.

### technology-science explainer
- **MIT Technology Review** (United States, en) — Explains why AI chips are moving to glass cores: organic resin substrates are warping and cracking under ever-larger multi-die packages, while glass offers flatness, dimensional stability and finer interconnect, the material precondition for next-generation HBM-heavy AI accelerators.
