Abstract:
A plasma source array comprising:a set of at least two plasma sources located opposite a substrate processing location, where each of said at least two plasma sources provides plasma processing to a corresponding plasma processing track produced as said substrate is moved relative to said plasma source;a set of at least two film quality detectors, each detector being located to measure a physical parameter of a film deposited in a corresponding plasma source's processing track;a set of at least two plasma source control modules, each one being matched with a corresponding plasma source of said at least two plasma sources and a corresponding film quality detector of said at least two film quality detectors, wherein each control module controls at least one of at least two external active elements needed to achieve and maintain a plasma from each of said set of at least two plasma sources based on information about film quality received from the corresponding film quality detector.
