IMPACT OF GENERATIVE AI

Adoption of Generative AI to Accelerate the Demand for Silicon Interposer and Bridge Technologies in Advanced Packaging

The increasing demand for silicon interposers and silicon bridges is due to the requirements of high-performance AI processors requiring high memory bandwidth and high-speed chip-to-chip communication for training and inference of large language models. Packaging technologies such as these allow the integration of multiple logic dies with high-bandwidth memory in one package, resulting in better performance, better power efficiency, and increased speed of data transfers. The growing size and complexity of AI chips have led semiconductor companies to adopt interposer and bridge-based architectures to enable chiplet designs and heterogeneous integration. Advanced packaging capacity investment and the development of new packaging platforms are also being driven by this trend among foundries and OSATs. For instance,

• In April 2025, Intel Foundry engaged into a collaboration with Keysight Technologies on EMIB-T silicon bridge technology for next-generation AI and data-center solutions, indicating continued ecosystem build-out around bridge packaging.

INTERPOSER AND SILICON BRIDGE MARKET TRENDS  

Shift toward Silicon Bridge and Hybrid Architectures to Enhance Scalability and Efficiency in Advanced Semiconductor Packaging

The semiconductor industry is increasingly shifting from full silicon interposers toward bridge and hybrid interconnect structures to improve scalability, reduce silicon usage, and support larger multi-die AI packages. The use of large interposers makes it increasingly difficult for chip manufacturers to maintain low overall costs and high yield rates, as chip sizes and high bandwidth memory (HBM) stacks continue to grow in size and complexity. Bridge architectures only use silicon in areas where high-density interconnects are needed, allowing for improved yield rates and more efficient package designs.

Manufacturers are also using hybrid solutions that combine RDL interposers with embedded silicon bridges, as these hybrid solutions allow for flexible chiplet integration and can accommodate larger package sizes for AI accelerators and high-performance computing processors. Over time, this trend toward bridge-based architectures and hybrid packaging platforms is likely to accelerate the adoption of these alternatives in the development of AI and HPC semiconductor designs. For instance,

• In May 2025, ASE Technology Holding announced FOCoS-Bridge with TSV, an advanced packaging platform designed to improve bandwidth, I/O density, and thermal dissipation for AI and HPC applications. This reflects the growing shift toward bridge-based packaging architectures.

Rising Shift toward Chiplet-based Semiconductor Designs to Fuel Market Growth

The market is largely influenced by the greater degree of use of chiplet-type semiconductor designs in areas where smaller dies are joined into one package to provide improved performance, scalability, and manufacturing yields. Due to the increasing use of chiplet-type architecture, semiconductor manufacturers are making less use of monolithic single die designs in favor of chiplet architecture, which requires the use of very high-density die-to-die interconnect, making silicon interposers and silicon bridges a critical element of semiconductor packaging technology. As semiconductor chip complexity continues to increase, chiplet-based architectures will continue to assist in reducing chip development costs and improving the flexibility of processor design, driving the adoption of chiplet architectures across data center processors, GPUs, and AI accelerators. These factors are likely to drive interposer and silicon bridge market growth. For instance,

• In November 2024, Amkor Technology and TSMC announced an expanded partnership to collaborate on advanced packaging and test in Arizona, aimed at providing a more integrated manufacturing and packaging flow for next-generation multi-die and chiplet-based semiconductor products in the U.S.

MARKET RESTRAINTS

High Packaging and Manufacturing Costs May Hinder Market Growth

Advanced semiconductor packaging solutions that use silicon interposers and silicon bridges involve a variety of complex fabrication processes, e.g. TSVs, high-density redistribution layers, and others, which significantly increase manufacturing costs relative to traditional semiconductor packaging. Large interposers, such as those used in AI accelerator or HPC processors, require significantly larger areas of silicon than do less expensive packaging technologies, and advanced substrates to build out the interposer, which further increase material and manufacturing costs. If companies decide to use these types of advanced packaging technologies, they will need to balance the advantages of using these technologies versus the cost and expense associated with their implementation. As many of the semiconductor applications and small designers are cost-sensitive, they may be limited in their options for using advanced packaging technologies.

MARKET OPPORTUNITIES

Emergence of 3D and 3.5D Advanced Packaging Platforms to Create New Opportunities for Market Growth

The growth of advanced 3D and 3.5D packaging platforms means strong growth for the market due to their ability to provide a far greater number of processors, memory, and connections in one package compared to conventional (2D) packaging. The need for increased density within a contained package is critically important to AI accelerators and high-performance computing processors as they require a means to integrate multiple chiplets and larger HBM designs without the restrictions of reticle size and board-level signal degradation.

In summary, advanced 3D and 3.5D packaging platforms are broadening the overall number of applications available to both silicon interposers and silicon bridges for next-generation semiconductor packaging. For instance,

• In January 2025, Broadcom announced the industry’s first 3.5D face-to-face (F2F) packaging technology for AI XPUs, stating that the platform combines 3D chip stacking with a smaller interposer footprint to improve performance, efficiency, and cost.
