Molybdenum target is a special metal target made of molybdenum, mainly used in high-tech fields. Molybdenum, a silver-white metal, is known for its high melting point and good electrical and thermal conductivity, which allow it to remain stable in high-temperature or high-pressure environments. Therefore, molybdenum targets play an important role in semiconductor manufacturing, thin film deposition technology, photovoltaic industry and medical imaging equipment. Molybdenum targets can be produced by hot isostatic pressing (HIP), smelting, chemical vapor deposition (CVD), and physical vapor deposition (PVD). Each method has its own characteristics and scope of application. Choose the appropriate preparation technology. Depends on the end use of the required molybdenum target, required performance and economic considerations.
Bonded copper backing not only improves target performance but also helps reduce operating costs, which is especially important for industries that rely on long-term, stable thin film deposition processes. It has the following benefits:
1. Improve thermal conductivity efficiency: Copper has extremely high thermal conductivity (about 400 W/m·K), which is much higher than molybdenum. Binding the molybdenum target to the copper backing plate can significantly improve the overall heat conduction efficiency of the target. During high-speed coating processes, this helps conduct heat away from the molybdenum target more quickly, thus preventing the target from overheating.
2. Reduce thermal stress: During the deposition process, the thermal stress on the target material may cause cracks and fractures. The high thermal conductivity of the copper backing plate helps disperse heat evenly and reduces thermal stress concentration on the molybdenum target, thereby reducing heat-induced damage.
3. Extend the service life: By reducing thermal stress and improving thermal efficiency, the copper backplate can significantly extend the service life of the molybdenum target. This combination helps prevent premature target wear or damage during use, resulting in less frequent replacement and lower long-term costs.
4. Improve mechanical stability: The addition of copper backing plate also enhances the overall mechanical stability of the target. This is especially important during high-speed deposition processes, as it helps maintain the structural integrity of the target and reduce damage due to mechanical shock or vibration.
5. Strong adaptability: This binding method can adjust the thickness and shape of the copper backplane according to different application requirements, providing greater flexibility and adaptability. This allows molybdenum targets to better meet the requirements of specific deposition equipment and processes.
