Publication number: 20110048467Abstract: An upper processing head includes a topside module defined to apply a cleaning material to a top surface of a substrate and then expose the substrate to a topside rinsing meniscus. The topside module is defined to flow a rinsing material through the topside rinsing meniscus in a substantially uni-directional manner towards the cleaning material and opposite a direction of movement of the substrate. A lower processing head includes a bottomside module defined to apply a bottomside rinsing meniscus to the substrate so as to balance a force applied to the substrate by the topside rinsing meniscus. The bottomside module is defined to provide a drain channel for collecting and draining the cleaning material dispensed from the upper processing head when the substrate is not present between the upper and lower processing heads. The upper and lower processing heads can include multiple instantiations of the topside and bottomside modules, respectively.Type: ApplicationFiled: November 9, 2010Publication date: March 3, 2011Applicant: Lam Research CorporationInventors: Cheng-Yu (Sean) Lin, Mark Kawaguchi, Mark Wilcoxson, Russell Martin, Leon Ginzburg

Publication number: 20100313917Abstract: Apparatus and methods for removing particle contaminants from a solid surface includes providing a layer of a viscoelastic material on the solid surface. The viscoelastic material is applied as a thin film and exhibits substantial liquid-like characteristics. The viscoelastic material at least partially binds with the particle contaminants. A high velocity liquid is applied to the viscoelastic material, such that the viscoelastic material exhibits solid-like behavior. The viscoelastic material is thus dislodged from the solid surface along with the particle contaminants, thereby cleaning the solid surface of the particle contaminants.Type: ApplicationFiled: June 16, 2009Publication date: December 16, 2010Applicant: Lam Research Corp.Inventors: Mark Naoshi Kawaguchi, David Mui, Mark Wilcoxson

Publication number: 20100258142Abstract: The embodiments provide apparatus and methods for removing particles from a substrate surface, especially from a surface of a patterned substrate (or wafer). The cleaning apparatus and methods have advantages in cleaning patterned substrates with fine features without substantially damaging the features on the substrate surface. The cleaning apparatus and methods involve using a viscoelastic cleaning material containing a polymeric compound with large molecular weight, such as greater than 10,000 g/mol. The viscoelastic cleaning material entraps at least a portion of the particles on the substrate surface. The application of a force on the viscoelastic cleaning material over a sufficiently short period time causes the material to exhibit solid-like properties that facilitate removal of the viscoelastic cleaning material along with the entrapped particles. A number of forces can be applied over a short period to access the solid-like nature of the viscoelastic cleaning material.Type: ApplicationFiled: April 14, 2009Publication date: October 14, 2010Inventors: Mark Naoshi Kawaguchi, David Mui, Mark Wilcoxson
