Description

Technical Field

[0001] This utility model relates to the field of rotating cathode magnetic rod technology, and in particular to a rotating cathode magnetic rod deformation support plate structure. Background Technology

[0002] Vacuum sputtering coating technology has been widely used in semiconductor, solar energy, optics, and aerospace fields. Among them, magnetron sputtering coating has the advantages of fast sputtering speed, simple equipment, and easy control, making it suitable for long-term mass production. Magnetron sputtering coating refers to a coating technology that uses the coating material as the target cathode, and uses argon ions to bombard the target material to generate cathode sputtering, which sputters the target material atoms onto the workpiece to form a deposition layer.

[0003] Currently, the coating industry has increasingly stringent requirements for film uniformity, long-term stability, and the repeatability and precision of magnetic field adjustment. While the uniformity of thin film deposition is influenced by factors such as the uniformity of the process gas and the electric field in the coating equipment, the most critical factor is the uniformity of the magnetic field of the rotating cathode magnetic rod. Therefore, the rotating cathode magnetic rod not only requires excellent magnetic field uniformity in its initial state of use, but also needs to continuously adjust the magnetic field strength during the continuous coating process to ensure the continuity and uniformity of thin film deposition.

[0004] When adjusting the magnetic field strength, it is usually necessary to adjust the distance between the magnetic strip and the target material at a specific point. However, the magnetic strip in the existing magnetic rod structure is usually installed on a metal plate. When the adjustment force is small, the metal plate cannot deform. When the adjustment force is large, the deformation of the magnetic strip at that point exceeds the adjustment range. This makes single-point adjustment quite difficult. Utility Model Content

[0006] To solve the above technical problems, this utility model provides a rotating cathode magnetic rod deformation support plate structure, including a deformation support plate, wherein multiple sets of magnetic strips are installed on the front side of the deformation support plate and multiple sets of online adjustment components are installed at intervals on the back side;

[0007] Under the action of any one of the online adjustment components, the deformation support plate in that area is deformed, thereby adjusting the distance between the magnetic strip and the target material in that area individually.

[0008] Preferably, the deformation support plate is equipped with three sets of magnetic strips, two of which are N-pole magnetic strips installed on both sides of the deformation support plate respectively; the other set is an S-pole magnetic strip installed between the two sets of N-pole magnetic strips.

[0009] Preferably, each set of magnetic strips is composed of several magnetic blocks arranged sequentially along the length of the deformation support plate.

[0010] Preferably, the mounting surface of the online adjustment component of the deformation support plate is provided with a plurality of first deformation grooves spaced apart, and the plurality of first deformation grooves are staggered with the mounting positions of the plurality of online adjustment components.

[0011] Preferably, the magnetic strip mounting surface of the deformation support plate is provided with a plurality of second deformation grooves spaced apart.

[0012] Preferably, multiple second deformation grooves are arranged in pairs on both sides of the mounting position of the online adjustment component.

[0013] Preferably, the deformation support plate has end plate slots machined at both ends for installing sealing end plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The deformation support plate disclosed in this utility model has a first deformation groove on the front side that is staggered with the mounting positions of multiple online adjustment components, and a second deformation groove on both sides of the mounting positions of the online adjustment components in pairs on the back side. This allows the deformation support plate at each adjustment point to deform more easily under the action of the online adjustment components, thus achieving the purpose of precise adjustment of the rotating cathode magnet.
