  • Patent number: 6143143
    Abstract: The invention relates to apparatus for use in the coating of surfaces of substrates by Physical Vapor Deposition systems (PVD) wherein the deposition in material is applied onto the said surfaces by the sputtering of the same using the PVD system. The invention provides means for preventing sputtering material from applying or landing onto surfaces other than which is desired to be coated in the said coating process. The masking means allow the prevention and/or removal of such material which is known as backscattered material and the invention described claims protection for several embodiments and methods of achieving this thereby improving subsequent adhesion propertied and optical quantities, if applicable, of the coating.
