Summary:The present invention generally relates to an apparatus and a method for mounting a rotational disk and more particularly, relates to an apparatus and a method for mounting a conditioning disk onto a conditioning head for use in a chemical mechanical polishing apparatus that is capable of preventing slurry from being siphoned into the control system. An apparatus and a method for mounting a conditioning disk to a conditioning head for use in a chemical mechanical polishing apparatus. A torroidal-shaped bearing mount is fixedly mounted to a conditioning arm of the CMP apparatus for receiving a ball bearing and a cylinder rotator. A cylinder shaft is mounted inside a cylinder chamber defined by the cylinder rotator and is further equipped with a piston mounted at near a top end of the shaft which has an elastomeric gasket mounted on an outer rim for sealingly engaging a sidewall in the cylinder chamber. A disk holder is mounted to a bottom end of the cylinder shaft by a universal connector/universal mount such that the disk holder, with a conditioning disk mounted thereon, can be operated to follow a contour of the polishing disk by tilting to an angle of at least ±30° from a horizontal plane.
