Word Count : 240
Chemical Vapour Deposition (CVD) and Physical Vapour Deposition (PVD) are two distinct thin film deposition techniques used in materials science. In CVD, a chemical reaction occurs between gaseous reactants on the substrate surface, leading to the formation of a solid film. The process typically requires high temperatures and results in films with excellent conformity and uniformity, even on complex surfaces. ________ _______ ____ ________ ______ _________ _____ ________ _____ ____ ____.
