Intel’s EMIB Interconnect Solution Outperforms Traditional 2.5D Chips: Offers Cost Savings, Simplified Design, and Enhanced Flexibility

Intel has recently highlighted the advantages of its Embedded Multi-die Interconnect Bridge (EMIB) technology in comparison to conventional 2.5D packaging solutions, showcasing its superior capabilities for advanced chip design.

Intel’s EMIB Outperforms Traditional 2.5D Packaging Methods

EMIB technology, developed by Intel, has been integrated into several of its advanced chips, including prominent examples like the Ponte Vecchio, Sapphire Rapids, Granite Rapids, Sierra Forest, and the upcoming Clearwater Forest line. This innovative interconnect solution demonstrates Intel’s commitment to improving chip performance and scalability.

The company has laid out its plans to enhance its packaging capabilities for future generations of chips, both those manufactured internally and for its foundry clients. The focus is on extensive packages that leverage EMIB along with various proprietary packaging technologies. The design targets data centers and incorporates multiple chiplets interconnected through EMIB technology.

Competitors like TSMC utilize traditional 2.5D and 3D packaging technologies, relying on a silicon interposer situated between the dies (or chiplets) and the package substrate. This interconnection is achieved through a network of wires passing through the silicon, known as Through Silicon Vias (TSVs).

Intel points out several disadvantages inherent in 2.5D technology. The need for additional silicon solely for interconnectivity inflates costs, and as chip sizes increase, so does the complexity of the package design, impacting yield rates adversely due to TSVs. Additionally, there are constraints on die size and flexibility which restrict the mixing of various compute and memory dies.

In contrast, EMIB technology eliminates the need for a large silicon interpose, embedding smaller bridges directly within the substrate where dies need to connect. This innovative approach allows for a recap of capabilities as EMIB continues to evolve. The technology includes two major variants:

EMIB 2.5D

This variant offers an efficient, cost-effective means to interconnect multiple complex die.

Ideal for logic-logic and logic-high bandwidth memory (HBM) applications.
EMIB-M integrates MIM capacitors, whereas EMIB-T incorporates TSVs.
The silicon bridge is embedded in the package substrate, facilitating shoreline-to-shoreline connections.
EMIB-T simplifies the integration of IP from various packaging designs.
Streamlined supply chain and assembly processes.
Proven technology in mass production since 2017, extensively used by Intel and partners.

EMIB 3.5D

This version combines EMIB and Foveros technology in a single package.

Supports flexible heterogeneous systems by enabling a mix of several dies.
Well-adapted for applications requiring multiple 3D stacks in a unified package.
Used in the Intel Data Center GPU Max Series, featuring over 100 billion transistors across 47 active tiles and five process nodes.

In summary, Intel’s EMIB technology provides significant advantages such as design flexibility and scalability that are challenging to achieve with traditional 2.5D methods. The key benefits highlighted by Intel include:

Consistent package yield rates
Opportunities for cost reduction
Simplified design processes

As Intel increases its focus on semiconductor fabrication and aims for greater visibility with its upcoming technologies, including 14A, advanced packaging solutions like EMIB will play a crucial role. Enhancements to technologies like the “T”variant and Foveros packaging have attracted significant interest, intensifying the competition in a field traditionally dominated by TSMC. The success of the 14A technology could herald a new era for advanced chip production in the United States.
