Abstract:
The present invention is a self-organization composition for pattern formation comprising a block copolymer [A] containing a polystyrene block having styrene units and a polyalkyl(meth)acrylate block having alkyl(meth)acrylate units, the self-organization composition for pattern formation being characterized in that the block copolymer [A] has groups (±) that are bonded to at least one terminus of the main chain and that contain hetero atoms. The hetero atoms are preferably at least one type selected from a group of oxygen, nitrogen, sulfur, phosphorus, tin, and silicon atoms.
Abstract:
The present invention relates to a method for forming a silicon oxide nanopattern, in which the method can be used to easily form a nanodot or nanohole-type nanopattern, and a metal nanopattern formed by using the same can be properly applied to a next-generation magnetic recording medium for storage information, etc., a method for forming a metal nanopattern, and a magnetic recording medium for information storage using the same. The method for forming a silicon oxide nanopattern includes the steps of forming a block copolymer thin film including specific hard segments and soft segments containing a (meth)acrylate-based repeating unit on silicon oxide of a substrate; conducting orientation of the thin film; selectively removing the soft segments from the block copolymer thin film; and conducting reactive ion etching of silicon oxide using the block copolymer thin film from which the soft segments are removed, as a mask to form a silicon oxide nanodot or nanohole pattern.
Abstract:
The invention relates to a method for the preparation by spatial distribution of light intensity of a surface with a raised pattern promoting spatial order and coherence acting as a guide for the organisation, on the nanometric and micrometric scales, of an overlay on the surface made of block copolymers in particular.
Abstract:
The invention provides a method for increasing the order of an array of polymeric micelles or of nanoparticles on a substrate surface comprising a) providing an ordered array of micelles or nanoparticles coated with a polymer shell on a substrate surface and b) annealing the array of micelles or nanoparticles by ultrasonication in a liquid medium which is selected from the group comprising H 2 0, a polar organic solvent and a mixture of H 2 0 and a polar organic solvent. In a related aspect, the invention provides the highly ordered arrays of micelles or nanoparticles obtainable by the methods of the invention.
Abstract:
Methods for fabricating sublithographic, nanoscale arrays of openings and linear microchannels utilizing self-assembling block copolymers, and films and devices formed from these methods are provided. Embodiments of the invention use a self-templating or multilayer approach to induce ordering of a self-assembling block copolymer film to an underlying base film to produce a multilayered film having an ordered array of nanostructures that can be removed to provide openings in the film which, in some embodiments, can be used as a template or mask to etch openings in an underlying material layer.
Abstract:
L'invention a trait à un procédé de préparation d'un film polymérique présentant en surface des motifs nanométriques et étant microstructuré dans son épaisseur sur tout ou partie de celui-ci selon un système particulier comprenant les étapes suivantes : - une étape de choix d'au moins un copolymère bloc apte à se microstructurer selon le système particulier susmentionné à une température et selon au moins une épaisseur prédéterminée, ladite épaisseur prédéterminée correspondant à l'épaisseur du film pour tout ou partie duquel on souhaite la microstructuration selon le système particulier susmentionné ; - une étape de choix d'au moins un moule apte à conférer, après application sur un film comprenant ledit copolymère bloc, l'épaisseur prédéterminée et lesdits motifs nanométriques; et - une étape d'application dudit moule sur un film comprenant ledit copolymère bloc tout en chauffant à ladite température prédéterminée, moyennant quoi l'on obtient ledit film défini en objet.
