Plasma-Enhanced Chemical Vapor Deposition (PECVD) is a versatile thin-film deposition technology that enables low-temperature processing while maintaining high-quality film properties. Its applications span across microelectronics, photovoltaics, optical coatings, and protective surfaces. PECVD's ability to deposit a wide range of materials—from dielectric insulators to conductive metals—at relatively low temperatures makes it indispensable in modern manufacturing and research. The technology's unique combination of plasma activation and (chemical vapor deposition)[/topic/chemical-vapor-deposition] principles allows for precise control over film composition and structure, meeting diverse industrial and scientific needs.
