Diamond Coating｜CVD Diamond Heat Dissipation Film and Wear-Resistant Coating Technology
Production Description
Diamond thin films possess excellent physical and chemical properties, including high hardness, high thermal conductivity, excellent wear resistance, low friction coefficient, good electrical insulation, and chemical stability. These characteristics make diamond films suitable for a wide range of applications, including mechanical processing, semiconductor heat dissipation, optoelectronic components, high-power electronics, and surface treatment of advanced materials.
With the rapid development of AI, high-performance computing (HPC), electric vehicles, and third-generation semiconductors, the power consumption and heat density of chips and high-power components continue to increase. As traditional metal heat dissipation materials and external cooling methods gradually approach their limits, efficiently transferring heat away from chip cores, packaging interfaces, and power device hotspots has become a critical factor affecting device performance, stability, and service life.
Diamond is one of the materials with the highest known thermal conductivity, reaching over 2000 W/(m·K), approximately five times that of copper and eight times that of aluminum. Compared with traditional metal materials, diamond heat dissipation films can help rapidly remove localized hotspots and reduce heat accumulation in high-power components during long-term operation.
In addition, diamond has a low thermal expansion coefficient, which is closer to semiconductor materials such as silicon and silicon carbide (SiC). This helps reduce thermal stress and interface reliability risks caused by thermal cycling. Therefore, CVD diamond films are not only suitable for wear-resistant coatings, but also have strong potential as thermal management materials for semiconductors and high-power electronic components.
Heat Dissipation and Semiconductor Applications:
Diamond heat dissipation films can be applied to AI chips, GPUs, high-bandwidth memory (HBM), SiC/GaN third-generation semiconductors, high-power electronic components, optoelectronic devices, and heat dissipation substrates.
In high-power-density devices, if hotspots cannot be removed in time, they may cause device throttling, reduced efficiency, or lower reliability. Through CVD diamond coating technology, diamond films can be deposited on silicon carbide, ceramics, metals, or other special substrates based on substrate conditions and heat dissipation requirements, helping improve thermal conduction and surface protection.
Application Areas:
1. Semiconductor and High-Power Electronics Heat Dissipation
Suitable for AI chip heat dissipation, third-generation semiconductors, SiC/GaN power devices, high-power modules, heat dissipation substrates, and electronic packaging thermal management.
2. Cutting Tools and Wear-Resistant Processing
Suitable for processing graphite, ceramics, aluminum, copper, carbon fiber, glass fiber, PCB electronic circuit boards, and non-ferrous metals, helping improve tool life and machining stability.
3. Optoelectronics, Medical, and Precision Components
Suitable for high-power lasers, optical components, medical devices, precision molds, and high-reliability surface protection applications.
Application Example:
Creating Nano Technologies can conduct CVD diamond film process evaluations based on different substrate materials, film thickness requirements, and application scenarios. For example, diamond films can be coated onto silicon carbide substrates, with film thickness adjusted according to application needs, for use in semiconductor heat dissipation, high-power device thermal management, or special surface protection.
