  • Patent number: 8226775
    Abstract: The embodiments of the present invention provide methods for cleaning patterned substrates with fine features. The methods for cleaning patterned substrate have advantages in cleaning patterned substrates with fine features without substantially damaging the features by using the cleaning materials described. The cleaning materials are fluid, either in liquid phase, or in liquid/gas phase, and deform around device features; therefore, the cleaning materials do not substantially damage the device features or reduce damage all together. The cleaning materials containing polymers of a polymeric compound with large molecular weight capture the contaminants on the substrate. In addition, the cleaning materials entrap the contaminants and do not return the contaminants to the substrate surface. The polymers of one or more polymeric compounds with large molecular weight form long polymer chains, which can also be cross-linked to form a network (or polymeric network).

  • Publication number: 20120132234
    Abstract: A cleaning system for removing contaminants on a surface of a patterned substrate for defining integrated circuit devices is provided. The system includes a substrate carrier for supporting edges of the patterned substrate, and a cleaning head positioned over the patterned substrate. The cleaning head includes a plurality of dispensing holes to dispense a cleaning material on the surface the patterned substrate for defining integrated circuit devices, wherein the cleaning material includes polymers of a polymeric compound. The cleaning head is coupled to a storage of the cleaning material, which is coupled to the cleaning material preparation system. A support structure holds the cleaning head in proximity to the surface of the patterned substrate.

  • Patent number: 8084406
    Abstract: The embodiments of the present invention provide apparatus for cleaning patterned substrates with fine features with cleaning materials. The apparatus using the cleaning materials has advantages in cleaning patterned substrates with fine features without substantially damaging the features. The cleaning materials are fluid, either in liquid phase, or in liquid/gas phase, and deform around device features; therefore, the cleaning materials do not substantially damage the device features or reduce damage all together. The cleaning materials containing polymers of a polymeric compound with large molecular weight capture the contaminants on the substrate. In addition, the cleaning materials entrap the contaminants and do not return the contaminants to the substrate surface.
