POLYCRYSTALLINE DIAMOND HEAT SPREADER

Large-Area Heat Dissipation: The Optimal Balance of Performance and Cost

Polycrystalline diamond heat spreaders are fabricated using CVD (chemical vapor deposition) technology. By leveraging the advantage of polycrystalline structures in producing large-size substrates, they deliver thermal conductivity far superior to traditional metals such as copper and aluminum while meeting the large-area heat-dissipation coverage requirements of high-power components produced in volume. They are the preferred thermal-management material for applications requiring an optimal balance of performance and cost efficiency.

CORE FEATURES & ADVANTAGES

Core Features and Advantages

Outstanding Thermal Conductivity: Thermal conductivity can reach 1,000–1,800 W/m·K, far exceeding traditional thermal-management materials such as copper (~400 W/m·K) and aluminum (~235 W/m·K)

Large-Size Manufacturing Capability: Available in large-area substrate sizes from 2" to 6", without the size limitations of single-crystal growth, meeting the coverage requirements of package- and chip-level thermal management

Excellent Cost Efficiency: Compared with single-crystal diamond growth, it offers higher production efficiency and more consistent yields, making it suitable for volume production and cost-sensitive applications

Stable Mechanical and Chemical Properties: Wear-resistant and corrosion-resistant, enabling long-term stable operation in high-power, high-temperature environments

APPLICATIONS

Key Applications

Package submounts for AI chips and high-power computing components

Thermal-management solutions for large-area heat sources such as CPUs and GPUs

Thermal substrates for electronic components such as power amplifiers and high-power LEDs

Volume-produced electronic products requiring both extensive heat-dissipation coverage and cost control
