What are the application scenarios of vacuum CVD coating system?

The vacuum CVD (Chemical Vapor Deposition) coating system has a wide range of applications in various high-tech and industrial fields due to its ability to accurately control the composition, structure, and properties of thin films. Here are some main application scenarios:
Semiconductor industry:
In integrated circuit manufacturing, vacuum CVD is used to deposit metal layers (such as copper and aluminum) as wires, as well as to deposit insulation layers (such as silicon dioxide and silicon nitride) as isolation layers.
Deposition of diffusion barrier layers (such as titanium nitride) to prevent metal atoms from diffusing in semiconductors.
Deposition of high-k dielectric constant materials to reduce leakage current in chips.
In the field of optics:
Coating of optical components (such as mirrors, lenses, filters, etc.) to increase their reflectivity, transmittance, or selectively absorb light of specific wavelengths.
Prepare anti reflective coatings to reduce reflection losses on the surface of optical components.
In fiber optic communication, depositing optical waveguide materials and gain media.
Solar energy industry:
Preparation of transparent conductive oxide (TCO) thin films, such as indium tin oxide (ITO), in solar panels to improve photoelectric conversion efficiency.
Deposition of anti reflective coatings to enhance the absorption of light by solar cells.
