    摘要: A conformal disk holder for holding a rotating disk against a surface of a polishing pad is described. The conformal disk holder can be used for any polishing apparatus, but is particularly suited for use in a CMP pad conditioning disk. The conformal disk holder is constructed by a cover member, a flexural plate member and a base member. The flexural plate member has a center protrusion with a downwardly facing convex surface for intimately engaging an upwardly facing concave surface on a center protrusion of the base member. The intimate engagement between the convex surface and the concave surface allows at least a 5° tilt of the base member from a horizontal plane, and preferably allows a tilt between about 5° and about 30°.

    摘要: A method for off-line testing a polishing head used in a CMP polishing apparatus is disclosed. The method utilizes at least two sets of pressurizing/vacuuming/venting devices for the independent testing of at least two fluid chambers which may include a membrane chamber, a retaining ring chamber and an innertube chamber normally found in a CMP polishing head. The present invention further discloses an off-line testing apparatus for a chemical mechanical polishing head which includes at least two independent sets of pressurizing/vacuuming/venting devices for testing a CMP head that is equipped with at least two fluid chambers such as a membrane chamber, a retaining ring chamber and an innertube chamber. The method and apparatus can be used advantageously for testing a variety of defects in a CMP polishing head prior to the installation of the head into a CMP apparatus. The defects include leakage between the fluid chambers, loss of vacuum seal in the fluid chambers, and binding between the fluid chambers. A pressurizing source utilized may be a general nitrogen gas in a fabrication plant. The vacuum source may be factory vacuum.

    摘要: The present invention discloses a contamination prevention system and method of use having a contamination prevention shield that cooperates with a high pressure rinse apparatus to prevent contamination of particles within a CMP apparatus. The contamination prevention shield has a cleaning cup, two vertical side shields, a front vertical shield, and a floor that cooperate to prevent leakage of fluid splattered during a high pressure rinse of the CMP apparatus and an interior portion of a CMP apparatus housing; and a high pressure rinse apparatus connected to the contamination prevention shield having a conduit with at least one nozzle for dispensing cleaning fluid during a high pressure rinse cycle. Additionally, a plurality of contamination prevention shields may be used in combination with the high pressure rinse apparatus to further prevent contamination of an interior portion of the housing and the CMP apparatus.
