SK Hynix Selects Intel to Produce Next-Generation AI Memory

San Jose, Monday, 31 August 2026.
Memory giant SK Hynix is partnering with Intel Foundry to manufacture advanced memory components, leveraging packaging technologies that could cut costs by up to 50% compared to TSMC.

Strategic Diversification of Supply Chain

In a significant shift for the semiconductor industry, SK Hynix has confirmed plans to integrate Intel’s Embedded Multi-die Interconnect Bridge (EMIB) technology into its next-generation High Bandwidth Memory (HBM) production [1]. This announcement, made during the Hot Chips 2026 conference, marks a departure from the company’s historical reliance on Taiwan Semiconductor Manufacturing Company (TSMC) for silicon interposer integration [1][2]. The collaboration involves SK Hynix utilizing Intel Foundry for the manufacturing of base dies for its HBM4E memory stacks, transitioning from a single-vendor arrangement to a dual-sourcing strategy [3][6]. This move is driven by the need to mitigate supply chain risks and leverage Intel’s advanced packaging capabilities to support artificial intelligence workloads [4]. Industry observers note that SK Hynix explicitly mentioned EMIB in their presentation materials, confirming the partnership’s technical scope [5]. By diversifying its supplier base, SK Hynix aims to strengthen its price negotiation leverage amidst reported price increases from TSMC planned for 2027 [6].

Economic Implications and Cost Efficiency

The economic rationale behind this partnership centers on substantial cost reductions associated with advanced packaging. Intel’s EMIB-T technology offers a price advantage of up to 50% compared to TSMC’s CoWoS packaging solutions, depending on interposer requirements [1][4]. This cost differential is critical because base dies used in HBM4 are reportedly 3 to 4 times more expensive than the core DRAM dies produced in-house by SK Hynix [4][6]. Reducing the cost of these logic dies directly impacts the bottom line for the memory giant. Furthermore, TSMC base dies have become a focal point for cost containment, especially as TSMC plans to raise prices by 5% to 10% starting in 2027 for advanced processes [6]. By integrating Intel’s packaging, customers can potentially reallocate savings toward additional HBM memory capacity, thereby increasing overall revenue potential for SK Hynix [1]. The financial incentive is clear, as base die production represents a high-value segment of the memory stack supply chain [4].

Production Timelines and Facility Expansion

Looking ahead, Intel expects its advanced packaging revenue, driven largely by EMIB-T technology, to begin ramping up in the second half of 2027 [7]. The technology is projected to become a steady contributor in 2028 and reach full stride by 2029 [7]. Concurrently, SK Hynix is investing heavily in domestic production capacity to support these initiatives. The company has begun construction on an advanced packaging facility in West Lafayette, Indiana, with an investment exceeding $4 billion [4]. This facility is targeting volume production of next-generation HBM by the second half of 2029 [4]. While Intel Foundry is expanding its capabilities, the company has clarified that it has no plans to re-enter DRAM manufacturing itself, focusing instead on packaging and logic die production [7]. This timeline aligns with the broader industry shift toward 3D memory structures and vertical power delivery concepts supported by Through-Silicon Vias (TSVs) [1][3].

Competitive Landscape and Market Dynamics

The partnership occurs within a highly competitive foundry market where supplier dominance is shifting. Intel Foundry currently generates only 5% of its revenue from external customers, making a marquee client like SK Hynix critical for its turnaround strategy [6][7]. Meanwhile, competitors are also advancing; Samsung Electronics has reported HBM4 yield rates increasing from under 60% in February 2026 to approximately 80% as of August 2026 [6]. This improvement represents a significant gain in production efficiency over the six-month period 33.333 [6]. Additionally, Samsung has implemented price hikes of up to 15% on new orders, reflecting broader market pressures [6]. Intel’s appointment of former SK Hynix CEO Seok-Hee Lee as an executive vice president underscores its commitment to the memory packaging sector [7]. As the industry moves toward HBM4E and beyond, the collaboration between SK Hynix and Intel Foundry represents a pivotal realignment of the semiconductor supply chain [3][4].
