Abstract
A method for manufacturing a compound film comprising a substrate and at least one additional layer is disclosed. The method comprising the steps of depositing at least two chemical elements on the substrate and/or on the at least one additional layer using depositions sources, maintaining depositing of the at least two chemical elements while the substrate and the deposition sources are being moved relative to each other, measuring the compound film properties, particularly being compound film thickness, compound-film overall composition, and compound-film composition in one or several positions of the compound film, comparing the predefined values for the compound film properties to the measured compound film properties, and adjusting the deposition of the at least two chemical elements in case the measured compound film properties do not match the predefined compound film properties.
