Conformal film

A conformal film defines a morphologically uneven interface with another body and has a thickness that is the same everywhere along the interface. This is undoubtedly an idealization and may be used for abstract or theoretical purposes. Real films will exhibit thickness variations along edges, steps or other elements of the morphology of the interface but yet be considered conformal films depending on the magnitude of the thickness variations. Conformal films may be deposited by thin-film deposition methods, such as plating, chemical vapor deposition or atomic layer deposition.
