Key Findings: SEMI Advanced Packaging Summit 2026 Emphasizes HBM and 2.xD Packaging as Pivotal for Innovating AI/HPC Performance and Power Efficiency

The SEMI Advanced Packaging Summit 2026, held under the theme “Packaging the Future of AI – From Silicon to Photon,” delved into the evolving landscape and industrial implications of semiconductor packaging technologies in the era of Artificial Intelligence (AI). The summit highlighted market transformations driven by the explosive demand for AI semiconductors and crucial technologies enabling high performance and superior power efficiency. Specifically, advanced packaging solutions such as customized High-Bandwidth Memory (HBM) and Samsung’s 2.xD packaging portfolio were strongly emphasized as key enablers for dramatically boosting the performance of next-generation AI/HPC (High-Performance Computing) chips and addressing critical power efficiency challenges.

Technical & Business Details

Enhancing AI/HPC Chip Performance: The increasing complexity of AI models and the explosion of data volumes place unprecedented demands on chip processing power and memory bandwidth. HBM achieves significantly higher data throughput than conventional memory by vertically stacking multiple DRAM dies and connecting them to the processor over short distances. Furthermore, Samsung’s 2.xD packaging effectively integrates multiple chiplets (e.g., CPU, GPU, HBM) using silicon interposers or bridge technologies, optimizing overall system performance and power efficiency.
System Technology Co-Optimization (STCO): The summit underscored the importance of STCO, an approach that holistically optimizes chip, package, and system designs. This methodology aims to enhance overall system performance and power efficiency, moving beyond the mere maximization of individual component performance. This indicates that advanced packaging has transcended simple physical connectivity to become a strategic element deeply involved from the design phase.
“Silicon to Photon” Outlook: The theme “From Silicon to Photon” alludes to the potential integration of optical technologies (photonics) into packaging to overcome data transmission bottlenecks inherent in electrical signaling. This represents a significant direction for achieving ultra-high-speed and low-power data communication in the future.

Background & Industry Context

As the limits of semiconductor scaling (Moore’s Law) approach, advanced packaging technologies are being hailed as the “More than Moore” frontier, enabling continuous improvements in chip performance. Megatrends such such as AI, data centers, and autonomous driving are driving semiconductor demand, with the enhanced performance and power efficiency of AI chips being crucial for realizing sustainable computing. Strengthening supply chain resilience also remains a major factor driving international cooperation and technological innovation.

Strategic Significance & Outlook

The technological trends highlighted at the SEMI Advanced Packaging Summit are expected to accelerate dramatic improvements in AI/HPC chip performance and power efficiency, leading to advancements in data centers, proliferation of edge AI, and new scientific discoveries across various fields. From the perspective of adhesives and sealants, the development of even more innovative material solutions will be essential for ultra-high-density bonding, thermal management, electrical characteristics, and ensuring long-term reliability in HBM stacking and 2.xD integrated packages. This will position material suppliers to play an even more strategic role within the semiconductor ecosystem.
