What materials is the vacuum CVD coating system suitable for?

The vacuum CVD (Chemical Vapor Deposition) coating system is widely used for coating various materials due to its high efficiency, flexibility, and precise control of the composition, structure, and properties of the film. The following are the main types of materials suitable for vacuum CVD coating systems:
1. Metals and metal alloys
Metals such as copper, aluminum, tungsten, titanium, tantalum, etc. are used to prepare conductive layers, diffusion barrier layers, contact hole filling, etc.
Metal alloys, such as copper nickel alloys, titanium aluminum alloys, etc., are used for the preparation of thin films with specific performance requirements.
2. Ceramic materials
Oxide: such as silicon dioxide (SiO ₂), aluminum oxide (Al ₂ O3), titanium dioxide (TiO ₂), etc., used to prepare insulation layers, protective layers, anti reflective coatings, etc.
Nitrides, such as silicon nitride (Si3N4), aluminum nitride (AlN), etc., have excellent hardness, wear resistance, and thermal stability, and are commonly used in the preparation of hard coatings.
Carbides, such as silicon carbide (SiC), tungsten carbide (WC), etc., are used to prepare coatings with high hardness and wear resistance.
3. Semiconductor materials
Used for preparing active layers, insulating layers, conductive layers, etc. in semiconductor devices. For example, silicon (Si), germanium (Ge), silicon germanium alloy (SiGe), etc.
4. Composite materials
CVD technology can be used to prepare various composite thin films, such as metal ceramic composites, polymer based composites, etc., to meet specific application requirements.
5. Transparent conductive oxide (TCO)
Such as indium tin oxide (ITO), indium zinc oxide (IZO), etc., are used to prepare transparent conductive films for devices such as solar cells, touch screens, and displays.
6. Other special materials
Including but not limited to superconducting materials, ferroelectric materials, piezoelectric materials, magnetic materials, etc., these materials play important roles in specific application fields such as superconducting electronics, sensors, memory, etc.
