Abstract:
Particulate cleaning assemblies and methods for cleaning are disclosed. In one example, a device for removing particles from a backside surface of a substrate is described. The device includes a chamber body with a substrate chucking device, a particulate cleaning article positioned over the substrate supporting surface, an optical sensing device positioned under the particulate cleaning article and a substrate positioning device separates the particulate cleaning article and a substrate. In another example, a method for removing particles from a substrate is disclosed. The method includes positioning a substrate with a processing surface and a supporting surface in a process chamber. At least a portion of the substrate can be chucked to a substrate chucking device, the substrate chucking device having a substrate supporting surface with a particulate cleaning article positioned thereon. The substrate is then separated from the particulate cleaning article leaving particles behind.
