Application of molybdenum disc as coating substrate
Molybdenum wafer is widely used in various coating processes because of its excellent physical and chemical properties, especially in the fields of semiconductor, optoelectronics and optical films. This paper will discuss the advantages of moly disc as coating substrate and its application.
1. Excellent thermal conductivity
Molybdenum has excellent thermal conductivity, which allows it to effectively dissipate heat during the coating process. The coating process usually generates a lot of heat, and too high a temperature may cause the quality of the film to decline. The use of molybdenum disc as the substrate can effectively reduce the temperature of the substrate, so as to ensure the uniformity and density of the film layer and improve the quality of the coating.
2. High strength and wear resistance
Molybdenum wafer has excellent mechanical strength and wear resistance, making it able to withstand high pressure and high temperature environments during the coating process. For coating applications requiring high strength support, mo discs provide an excellent basis. Its resistance to deformation guarantees the stability of the film layer and reduces the risk of peeling or breakage during use.
3. Chemical stability
Molybdenum has good corrosion resistance and can resist the erosion of a variety of chemical media. During the coating process, many chemical gases or solutions may cause corrosion to the substrate, affecting the adhesion and stability of the film layer. The chemical stability of molybdenum wafer enables it to maintain good performance in harsh environments, ensuring the long-term effectiveness of the coating.
4. You're adaptable
Molybdenum wafer is suitable for a variety of coating technologies, such as physical vapor deposition (PVD), chemical vapor deposition (CVD), etc. In these technologies, molybdenum discs can be used as an effective substrate to support the deposition of different types of thin film materials, including metal films, oxide films and nitride films. Its adaptability enables the molybdenum wafer to play a role in a variety of application scenarios.
5. Application field
Molybdenum disc is widely used as coating substrate. In the semiconductor industry, molybdenum wafers are used as substrates for wafers to support the manufacture of high-performance electronic devices. In the optoelectronics industry, it is used to manufacture optical thin films and laser components; In the aerospace and automotive industries, molybdenum discs are also used to coat components to improve wear resistance and high temperature resistance.
