The Chemical Vapor Deposition (CVD) process is a versatile and widely used technique in various industries for depositing thin films and coatings on substrates. Its applications span across electronics, optics, energy, and materials science, where precise control over material properties is essential. CVD is particularly valued for its ability to produce high-quality, uniform, and durable coatings, making it indispensable in the fabrication of semiconductors, protective coatings, and advanced materials. The process involves the chemical reaction of gaseous precursors to form a solid material on a substrate, often under controlled temperature and pressure conditions. This method is highly adaptable, allowing for the deposition of a wide range of materials, including metals, ceramics, and polymers.
