Description

A physical vapor deposition vacuum chamber structure Technical Field

[0001] This utility model relates to the field of physical vapor deposition vacuum chamber technology, specifically a physical vapor deposition vacuum chamber structure. Background Technology

[0002] Physical vapor deposition (PVD) is a very common surface treatment technique that forms a thin film by evaporating or sputtering material onto a substrate surface. This method is widely used in modern industry, especially in electronics, optics, and metal processing. In short, PVD converts solid materials into gases, which are then condensed and deposited onto the target object to form a very thin film. All of this is done in a vacuum environment, ensuring that the deposition process is not affected by impurities in the air. It produces extremely high film quality, and the relatively low temperature during deposition minimizes thermal damage to the substrate, making it particularly suitable for materials with poor heat resistance and temperature sensitivity. The deposited film has high density, strong adhesion, and excellent surface smoothness and uniformity. It acts like an invisible protective umbrella, completely enveloping the substrate and preventing corrosion from the external environment.

[0003] However, traditional physical vapor deposition vacuum chambers have the following drawbacks:

[0004] Traditional physical vapor deposition vacuum chambers can only perform coating operations on products from a single direction, which cannot meet the needs of multi-sided coating of products and has low practicality. Summary of the Invention
