Intel Makes Advanced Packaging Its Own Foundry Focus: Former SK Hynix Chief to Scale EMIB-T and HBI

Key Takeaways

• Seok‑Hee Lee, ex‑SK hynix CEO, named EVP of Intel Foundry Advanced Packaging
• Intel separates front‑end wafer fab from back‑end packaging under new unit
• EMIB‑T targets package area 8× by 2026, 12× by 2028
• HBI uses copper‑to‑copper bonds for higher bandwidth, lower power
• Advanced Packaging becomes a standalone selling point for AI/HPC customers

Pulse Analysis

The semiconductor industry is moving past the era where the smallest process node alone defined competitiveness. AI accelerators and high‑performance computing systems now rely on heterogeneous chiplet architectures that combine logic, high‑bandwidth memory, networking and I/O in a single package. Intel’s decision to elevate Advanced Packaging into its own business unit reflects this shift, giving the back‑end a clear mandate, dedicated budget and executive oversight. Seok‑Hee Lee’s background in memory and large‑scale manufacturing positions him to bridge Intel’s logic expertise with the complex integration challenges of modern AI workloads.

Intel’s EMIB‑T and Hybrid Bonding Interface (HBI) are the technical pillars of the new strategy. EMIB‑T extends the proven Embedded Multi‑Die Interconnect Bridge by adding through‑silicon vias, enabling side‑by‑side chiplets to be linked with short, low‑loss power and signal paths. The company’s roadmap aims to expand package footprints to eight times a single reticle by 2026 and twelve times by 2028, a scale that could accommodate multiple HBM stacks and networking dies. HBI, by contrast, delivers ultra‑fine copper‑to‑copper bonds that shrink pitch, boost bandwidth and cut energy per bit, making it ideal for vertical stacking such as Foveros Direct 3D.

For customers, the restructuring promises a one‑stop shop: Intel can supply both the front‑end process (e.g., 18A, 14A) and the back‑end integration needed to ship a complete AI system. This end‑to‑end offering could attract fabless firms that currently split logic and packaging across multiple vendors, giving Intel a competitive edge over TSMC and Samsung, which focus primarily on wafer fabrication. However, success hinges on achieving high yields, thermal reliability and cost‑effective volume production of EMIB‑T and HBI. If Intel can deliver, it will redefine the foundry value proposition from silicon‑only to full‑system integration.
