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.
摘要翻译：公开了一种用于在CMP抛光装置中使用的抛光头的离线测试方法。该方法使用至少两组加压/抽真空/排气装置，用于对至少两个流体室进行独立测试，所述至少两个流体室可以包括通常存在于CMP抛光头中的隔膜室，保持环室和内管室。本发明还公开了一种用于化学机械抛光头的离线测试装置，其包括至少两组独立的加压/抽真空/排气装置，用于测试装配有至少两个流体室的CMP头，例如膜室，保持环室和内管室。该方法和装置可以有利地用于在将头部安装到CMP设备中之前测试CMP抛光头中的各种缺陷。这些缺陷包括流体室之间的泄漏，流体室中的真空密封损失以及流体室之间的结合。所用的加压源可以是制造设备中的一般氮气。真空源可以是工厂真空。

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.
