Diamond Composite Materials Provide A New Solution For The Heat Dissipation Problem Of Semiconductor Devices.

On January 23rd, Element Six, a high-tech materials company under diamond giant Delbis, announced the launch of a copper diamond composite material for semiconductor device heat dissipation on January 22nd, providing a new solution to the heat dissipation problem of semiconductor devices.

 

It is reported that the copper diamond composite material released by Element Six combines two materials that have excellent performance in the field of heat dissipation: copper, which is widely used in semiconductor device heat dissipation, and diamond, which has excellent thermal conductivity. Through a unique process, these two materials are perfectly combined to achieve a balance between thermal conductivity and thermal expansion coefficient between the two raw materials, thus achieving unprecedented heat dissipation effect.

Technical background and principles

Semiconductor devices generate a large amount of heat during operation, and if not dissipated in a timely manner, it can lead to a decrease in device performance, shortened lifespan, or even damage. Although traditional heat dissipation materials such as copper and aluminum have certain thermal conductivity, they often struggle to cope with the high thermal load of high-performance semiconductor devices. Therefore, it is particularly important to develop a new type of heat dissipation material with higher thermal conductivity.

 

Copper diamond composite materials were born based on this demand. It combines copper, which is widely used in the field of semiconductor device heat dissipation, with diamond, which has excellent thermal conductivity. Through a unique process, these two materials are perfectly combined to achieve a balance between thermal conductivity and thermal expansion coefficient between the two raw materials, thus achieving unprecedented heat dissipation effect. The thermal conductivity of this material is much higher than that of pure copper, which can effectively reduce the operating temperature of semiconductor devices and improve their performance and reliability.

 

Technical features and advantages

1. High thermal conductivity:

The thermal conductivity of copper diamond composite materials far exceeds that of pure copper, and can even reach over 1000 W/m • K. This characteristic enables it to quickly dissipate the heat generated by semiconductor devices in a very short period of time, thereby maintaining the stable operation of the devices.

 

2. Low thermal expansion coefficient: Diamond has a low thermal expansion coefficient, which makes the size change of copper diamond composite materials smaller when the temperature changes, which is conducive to improving the stability and reliability of equipment.

 

3. Excellent mechanical properties: The high hardness and strength of diamond endow copper diamond composite materials with excellent mechanical properties such as wear resistance and impact resistance, enabling them to maintain stable performance in harsh working environments.

 

4. Good processing performance: Copper diamond composite materials prepared through unique processes have good processing performance and can be easily processed into various shapes and sizes of heat dissipation devices.

 

Application Fields and Prospects

Copper diamond composite materials have broad application prospects in multiple fields due to their excellent performance:

 

1. High performance computing (HPC)/AI chips: With the rapid development of artificial intelligence and big data technology, the demand for high-performance computing chips is increasing day by day. The high thermal conductivity of copper diamond composite materials makes them an ideal heat dissipation material for these chips.

 

2. RF power amplifier: RF power amplifiers have a wide range of applications in wireless communication, radar, and other fields. Due to its high operating frequency and high power, the heat dissipation problem is particularly prominent. Copper diamond composite materials can effectively solve this problem and improve the performance and reliability of RF power amplifiers.

 

3. Power converter: Power converters play an important role in power electronic systems. The quality of its heat dissipation performance directly affects the stability and efficiency of the entire system. The application of copper diamond composite materials will help improve the heat dissipation performance of power converters, thereby enhancing the overall system performance.

 

4. High power semiconductor lasers: High power semiconductor lasers have a wide range of applications in medical, scientific research, industrial and other fields. The heat dissipation problem has always been one of the key factors restricting its performance improvement. The application of copper diamond composite materials is expected to solve this problem and promote the development of high-power semiconductor lasers.

 

Preparation methods and challenges

There are various preparation methods for copper diamond composite materials, including double coating method, powder metallurgy method, solution infiltration method, ultrasonic additive manufacturing method, electroplating method, high temperature and high pressure method, plasma sintering method, etc. However, these preparation methods all face certain challenges, such as uneven distribution of diamond particles and low interfacial bonding strength. Therefore, how to optimize the preparation process and improve the performance of composite materials is one of the current research focuses.

Future prospects

 

With the continuous development of technology, the demand for high-performance semiconductor devices will continue to increase, and the requirements for heat dissipation materials will also become increasingly high. Copper diamond composite material, as a new type of high thermal conductivity composite material, has broad application prospects and huge development potential in the field of semiconductor heat dissipation, and will become an important development direction in the future semiconductor heat dissipation field.
