As semiconductor power density continues to rise, thermal management has become a critical bottleneck. CVD diamond's exceptional thermal conductivity makes it the ideal choice for next-generation heat dissipation materials.

Industry Background

Power density in modern semiconductor devices continues to rise, making traditional thermal materials like copper and aluminum insufficient for high-performance chips.

Limitations of Traditional Thermal Materials

• Thermal conductivity of copper: approximately 400 W/(m·K)
• Thermal conductivity of aluminum: approximately 240 W/(m·K)
• Mismatched coefficient of thermal expansion with the chip leads to high thermal stress.

Advantages of CVD Diamond

CVD diamond offers significant advantages as a thermal management material:

1. Ultra-high thermal conductivity: 1500-2000 W/(m·K), which is 3-5 times that of copper
2. Low coefficient of thermal expansion: Closely matches silicon chips; excellent thermal compatibility
3. High insulation: Suitable for electronic device heat dissipation
4. Chemical StabilityCorrosion-resistant with long service life

Application Areas

CVD diamond thermal management materials are widely used in:

• 5G Base Station Power Amplifier
• Laser Diode
• High-Brightness LED
• High-performance computing chip

Market Outlook

Industry forecasts predict that the global diamond heat dissipation materials market will reach $1 billion in 2025, with a compound annual growth rate exceeding 20%.
