Patent number: 8227394Abstract: The embodiments of the present invention provide improved materials for cleaning patterned substrates with fine features. The cleaning materials have 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. To assist removing of particles from the wafer (or substrate) surfaces, the polymeric compound of the polymers can contain a polar functional group, which can establish polar-polar molecular interaction and hydrogen bonds with hydrolyzed particles on the wafer surface. The polymers of a polymeric compound(s) with a large molecular weight form long polymer chains and network.Type: GrantFiled: November 7, 2008Date of Patent: July 24, 2012Assignee: Lam Research CorporationInventors: Ji Zhu, Arjun Mendiratta, David Mui

Patent number: 8227381Abstract: Low molecular weight graft copolymer comprising a synthetic component formed from at least one or more olefinically unsaturated carboxylic acid monomers or salts thereof, and a natural component formed from a hydroxyl-containing natural moiety. The number average molecular weight of the graft copolymer is about 100,000 or less, and the weight percent of the natural component in the graft copolymer is about 50 wt % or greater based on total weight of the graft copolymer. Processes for preparing such graft copolymers are also disclosed.Type: GrantFiled: September 23, 2010Date of Patent: July 24, 2012Assignee: Akzo Nobel N.V.Inventors: Klin A. Rodrigues, Jannifer Sanders
