A CVD coating machine uses chemical reactions between gaseous precursors under high temperature, plasma, or catalysts to produce a solid thin film that is then deposited on a substrate. Its core principle is to utilize chemical reactions to deposit materials. This allows for a wide range of materials, high-quality films, and flexible processes, making it widely used in the semiconductor, photovoltaic, optical, and aerospace industries.

1. Semiconductor Manufacturing

Insulating layer deposition: Thin films such as silicon dioxide and silicon nitride are used to isolate conductive layers and reduce leakage current.

Epitaxial layer growth: Single-crystal silicon epitaxial layers are deposited on silicon wafers to improve transistor performance.

High-k dielectric materials: Hafnium-based oxides are used as gate dielectric layers in advanced chip manufacturing processes.

2. Photovoltaic Industry

Solar Cells: Amorphous silicon and microcrystalline silicon thin films are deposited to improve photoelectric conversion efficiency.

Transparent conductive films: Indium tin oxide is used as surface electrodes in solar cells to enhance light absorption and charge transfer.

3. Optical Fields

Anti-reflective coatings: Multi-layer thin films are deposited on the surface of lenses to reduce light reflection and increase light transmittance. Optical filters: Precisely control film thickness and refractive index to achieve selective transmission or reflection of specific wavelengths of light.

4. Aerospace and Wear-Resistant Coatings

Turbine Blade Coatings: Depositing thin films of alumina or yttria-stabilized zirconium oxide improves blades' high-temperature and corrosion resistance.

Tool Coatings: Depositing thin films of titanium nitride or titanium carbide enhances tool hardness and wear resistance.
