Abstract:
A plasma sputtering method wherein a sputtering target is placed on a cathode in a vacuum chamber, and a substrate is arranged on a holder in opposition to the sputtering target, to perform sputtering, the holder is operatively connected to a multi-chamber blade member mounted in a cavity and offset from a surface of the cavity to provide a circulate gaps, an input fluid connector for introduction of fluid to the cavity and an exit fluid connector for removing the fluid, comprising the steps of:introducing a fluid from the input fluid connector into an interior space formed in said holder on which the substrate is arranged in such a manner that the circulate gap provides a circumfusing of the fluid to each chamber of the blade member to enhance a cooling effect; andapply a fluid pressure through the input fluid connector and releasing the fluid through the exit fluid connector such as to exert a motive force to the holder to rotate, wherein the fluid is continuously drained after flowing through the interior space of the holder, whereby the substrate is cooled as being rotated.
