Chemical Vapor Deposition: Advanced Materials Manufacturing
What is CVD?
Chemical vapor deposition (CVD) is a materials processing technique used to produce high-purity, high-performance solid materials. In a CVD process, precursor gases are transported to the substrate surface where their gaseous species react or decompose to form a thin film of the desired material on the substrate surface. Precise control over parameters such as temperature, pressure, gas flow rates and reaction time allows for fabrication of films with exact properties and specifications. Some key advantages of CVD include high deposition rates, precise control over film properties, and ability to coat large and complex 3D shapes.
Wide Range of Materials and Applications
CVD is widely used for synthesis of electronic, optical, ceramic and protective coatings. Some common examples include Chemical Vapor Deposition of diamond-like carbon coatings on cutting tools for improved wear resistance, deposition of tungsten or polysilicon films for microchip interconnects and gates, growth of epitaxial silicon films for solar cells and power electronics, deposition of optical coatings on lenses and windows, and synthesis of titanium nitride coatings to enhance hardness and corrosion resistance of mechanical parts.
