Key Findings
Resonac has successfully developed next-generation thermal management materials that offer a groundbreaking solution to the urgent challenges of increasing power consumption and heat generation in AI (Artificial Intelligence) and HPC (High-Performance Computing) semiconductor packages. The newly developed thermal interface materials (TIMs) and encapsulants demonstrate a remarkable 30% improvement in thermal conductivity compared to existing products, enabling highly efficient heat dissipation from within the package. This technological achievement is crucial for maintaining low operating temperatures of AI chips, which in turn significantly improves chip stability, long-term reliability, and overall lifespan. AI chips perform vast computations for learning and inference, leading to substantial localized heat generation; without proper thermal management, their full potential cannot be realized. Resonac’s new materials represent a key technology for facilitating the further performance enhancement and widespread adoption of AI chips.
Technical and Material Details
The thermal management materials developed by Resonac achieve high thermal conductivity and low thermal resistance through the optimized compounding of nanocarbon materials and specialized ceramic fillers. Key features include:
- High Thermal Conductivity: Achieving over 30% improvement in thermal conductivity compared to conventional products, significantly enhancing heat transfer efficiency from the chip to the heatsink.
- Low Thermal Resistance: Excellent thin-film forming properties and interfacial adhesion minimize thermal resistance along the heat transfer path.
- High Reliability: Maintains stable performance under thermal cycling and humid conditions, ensuring long-term durability.
- Processability: Optimized processing characteristics such as coatability and curability, facilitating easy application in mass production processes.
These properties enable uniform heat dissipation and temperature management in advanced packaging structures that stack multiple chips, such as CPUs, GPUs, and High Bandwidth Memory (HBM).
Background and Industry Context
As semiconductor miniaturization approaches its physical limits, packaging technology has become a critical frontier for improving chip performance. Particularly with the advent of chiplet and 3D stacking technologies, power density within packages has dramatically increased, leading to a proportional rise in heat generation. This thermal issue is one of the biggest bottlenecks for scaling AI/HPC chip performance, making advancements in cooling solutions indispensable. Resonac’s latest development marks a significant step toward resolving this bottleneck and is expected to have a profound impact on the entire industry.
Strategic Significance and Outlook
Resonac plans to actively propose its newly developed thermal management materials to major semiconductor manufacturers and OSATs (Outsourced Semiconductor Assembly and Test providers) to achieve early market adoption. In the future, the company aims to continue developing materials with even higher thermal conductivity and capabilities to support diverse packaging structures, thereby solidifying its position as a leading company in solving semiconductor thermal issues. This technology is expected to find applications not only in AI but also across a wide range of high-density and high-heat fields, including 5G/6G communication, data centers, automotive, and power electronics.
