CVD Diamond Wafer Description

CVD Diamond Wafer has outstanding physical and chemical properties. It has an almost continuous band of optical transparency from UV to THz. Diamond is one type of carbon and has the highest hardness and thermal conductivity at the same time with high wear resistance, chemical inertness, and excellent radiation resistance. CVD Diamond Wafer can be used in multiple band ranges such as X-ray, ultraviolet, infrared, microwave, and so on.

It plays an important role in high energy input, low dielectric loss, high Raman gain, low beam distortion, erosion resistance, and other aspects that can’t be replaced by general optic materials. CVD Diamond Wafers are the best thermal management material for high heat flux devices due to their excellent thermal conductivity.

CVD Diamond Wafer Application

• Semiconductor Industry

• Heat Sinks: Polycrystal CVD Diamond Wafers are used as heat sinks in high-power electronic devices like power transistors, laser diodes, and other semiconductors because of their excellent thermal conductivity. They help manage heat dissipation, preventing overheating in critical components.
• Insulating Substrates: CVD diamond wafers are used as insulating substrates for high-performance semiconductors. Their electrical insulation and high thermal conductivity make them ideal for power devices and RF (Radio Frequency) components.

• Optical Industry

• Optical Windows: Due to their optical transparency in the UV to IR range, Single Crystal CVD Diamond Wafers are used to create high-performance optical windows for lasers, infrared sensors, and other high-energy optical systems.
• Lenses and Mirrors: Diamond is used in optical components where extreme durability and high optical transmission are required, such as lenses and mirrors for high-power lasers and military applications.
• Laser Components: CVD diamond is often used for laser components that need to withstand extreme power densities without degradation, including in high-powered laser systems used in manufacturing, medicine, and research.

• Medical devices: Industrial diamonds are also used in some medical fields, such as high-precision surgical tools, dental drills, etc. Due to the high hardness and good wear resistance of diamonds, it can improve the service life and precision of medical devices.

FAQs

Q1 How do CVD Diamond Wafers perform in thermal management?
CVD diamond wafers excel in thermal management due to their superior thermal conductivity, which is much higher than most metals, including copper. This makes them ideal for use in heat sinks and thermal spreading applications in high-power electronics, laser systems, and LEDs. The ability to efficiently dissipate heat helps prevent overheating in sensitive electronic components and improves their reliability and performance.

Q2. What is the cost of CVD Diamond Wafers?
The cost of CVD diamond wafers can vary depending on factors such as:

• Size and thickness: Larger wafers or wafers with thicker diamond layers generally cost more.
• Purity and quality: Wafers with higher purity and fewer defects may be priced higher.
• Customization: Custom-made wafers with specific properties (e.g., doped for conductivity) will often incur higher costs.

Q3 Can CVD Diamond Wafers be further processed?
Yes, CVD diamond wafers can be further processed for various applications. Common processing techniques include:

• Machining: Diamond wafers can be cut, polished, and coated to meet specific application needs.
