A method of forming a CMP pad includes providing a solution of a block copolymer (BCP), where the BCP includes a first segment and a second segment connected to the first segment, the second segment being different from the first segment in composition. The method further includes processing the BCP to form a polymer network having a first phase and a second phase embedded in the first phase, where the first phase includes the first segment and the second phase includes the second segment, and subsequently removing the second phase from the polymer network, thereby forming a polymer film that includes a network of pores embedded in the first phase. Thereafter, the method proceeds to combining the CMP top pad and a CMP sub-pad to form a CMP pad, where the CMP top pad is configured to engage with a workpiece during a CMP process.

The present invention provides a panel sheathing for making wall and roof structures in which the panels (e.g., wood boards, oriented strand boards, plywood, etc.) are pre-coated at a factory, before installation at the building/construction site, using a polymeric barrier coating having specific water permeability, self-sealing properties with respect to penetrated metal fasteners (e.g., nails) in accordance with ASTM D7349 (modified using 1.5-5.0 inches water depth in hydrostatic head testing over sample of coated panel in which a steel nail is driven to within ⅛ inches of being flush with the panel and conditioning the test specimen for 24 hours at 23° C. prior to hydrostatic loading), as well as anti-blocking properties whereby the coated panels can be transported in stacked configuration without sticking or disintegration of the polymeric barrier coating. The coated panels do not require the use at the installation site of felt paper, house wrap, or additional applied barrier coating to provide excellent weather barrier properties. The present invention also provides methods for constructing the panel sheathing structure as well as for making the coated panels.

One aspect of this invention is a novel functional polymer having a polydispersity from 1 to about 1.12 comprising at least one reactive moiety, selected from a moiety comprising at least one N-coordinative functional group having at least one lone pair of electrons, a moiety comprising a dialkylsilyl group, or a mixture of both groups, wherein said reactive moiety is present in said functional styrenic polymer either on a repeat unit, on an end group or on both, and said N-coordinative functional group is either a monodentate N-coordinative functional group, a polydendate N-coordinative group or a mixture of thereof, and said monodentate coordinative functional group is an azide moiety (—N.sub.3) or a cyano moiety (—CN). Another aspect of this invention is the use of these novel polymer to selectively deposit a DSA directing layer on a metallic substrate.

The present application relates to a method for preparing a patterned substrate. The method may be applied to a process of manufacturing devices such as, for example, electronic devices and integrated circuits, or other applications, such as manufacture of integrated optical systems, guidance and detection patterns of magnetic domain memories, flat panel displays, liquid crystal displays (LCDs), thin film magnetic heads or organic light emitting diodes, and the like, and may also be used to build a pattern on a surface used in manufacture of discrete track media, such as integrated circuits, bit-patterned media and/or magnetic storage devices such as hard drives.

The present disclosure provides an article. In an embodiment, the article includes a substrate and a coating on the substrate. The coating includes a composition. The composition includes a plurality of nanoparticles, each nanoparticle having a ligand linked to a surface of each nanoparticle. The composition includes a plurality of block copolymers.
