    摘要: The disclosure is directed to multilayer Mo/Si coatings for reflective mirrors used in extreme ultraviolet lithographic systems and to a method of making such mirrors using plasma ion assisted deposition (PIAD) techniques. The coating are deposited on a substrate suitable for EUV lithography, and are Mo/Si coating consisting of 40-100 Mo/Si periods, each period consisting on a Mo layer followed by a Si layer. Each of the individual Mo and Si layers is deposited to a specified or target thickness in the range of 2nm to 5nm, and the thicknesses are controlled to 0.1nm. A plasma from a plasma source is used to densify and smooth the substrate prior to deposition of the coating, and each layer of the coating is plasma densified and smoothed.

    摘要: The present invention relates to a sputter deposition system 10 and to methods of use thereof for processing substrates 12 using planetary sputter deposition methods. The sputter deposition system 10 includes a deposition chamber 14 having an azimuthal axis 16. A rotatable member 30 and 32 is situated in the chamber 14 and includes a plurality of magnetrons 34 provided thereon. Each magnetron 34 includes a corresponding one of a plurality of sputtering targets 36. The rotatable member 30, 32 is configured to position each of the magnetrons 34 to direct sputtered material from the corresponding one of the sputtering targets 36 to a deposition zone 50 defined in the deposition chamber 14. A transport mechanism 66 is situated in the deposition chamber 14 and includes an arm 68 rotatable about the azimuthal axis 16. A substrate holder 72 is attached to the arm 68 of the transport mechanism 66 and supports the substrate 12 as the arm 68 rotates the substrate holder 72 to intersect the deposition zone 50 for depositing sputtered material on the substrate 12.

    摘要: Known doctor rods (1) used as dosing elements in coating devices have a cylindrical steel base body on whose cover surface a chromium or ceramic layer of hard material is applied. According to the invention, the cracks and craters in the layer of hard material are closed by a joint which is produced by means of an ion implantation process, by the hard material reacting with the ions applied in a plasma. The improved doctor rods have a longer service life than known doctor rods.
