Vapor deposition (high vacuum)

Vapor deposition in a high vacuum is a process used in various industrial and scientific applications to coat surfaces. It is a process in which a material is applied to a substrate surface in the form of vapor to create a uniform coating.

The high vacuum is used to remove interfering gases and impurities from the substrate environment, which improves the quality and homogeneity of the coating. By lowering the pressure in the vacuum chamber, the likelihood of gas particles near the substrate is minimized, resulting in a clean and precise coating.

The vapor deposition process begins by heating the starting material until it reaches boiling point and vaporizes. The resulting vapor is then directed onto the surface of the substrate in a controlled manner, where it condenses and forms a thin layer. Depending on the application, different materials can be used for the coating, such as metals, oxides or organic compounds.

Vapor deposition in a high vacuum is used in numerous industries, including semiconductor manufacturing, optics, electronics and medical technology. It enables the production of precise coatings with customized properties, such as electrical conductivity, optical transparency or protection against corrosion.

Control of the vapor deposition process, including temperature, pressure and vapor rate, is critical to achieving the desired coating properties. Advances in vacuum technology and process engineering have helped to make vapor deposition in a high vacuum a versatile and efficient process for surface coating.
