摘要:
Generally, a method and apparatus for retaining polishing material is provided. In one embodiment, the apparatus includes a platen having a top surface, a plurality of channels and one or more vacuum ports. The top surface is adapted to support the polishing material. The plurality of channels are formed in a polishing area of the top surface. The vacuum ports are disposed in the platen and at least one port is in communication with at least one of the channels. Upon application of a vacuum to the ports, the channels remove fluids under the polishing material while securing the polishing material to the top surface.
摘要(中):
通常,提供了用于保持抛光材料的方法和装置。 在一个实施例中,该装置包括具有顶表面,多个通道和一个或多个真空端口的压板。 顶表面适于支撑抛光材料。 多个通道形成在顶表面的抛光区域中。 真空端口设置在压板中,并且至少一个端口与至少一个通道连通。 当向端口施加真空时,通道在将抛光材料固定到顶表面的同时移除抛光材料下面的流体。
