20090243126 | METHOD AND APPARATUS FOR IMPRINTING MICROSTRUCTURE AND STAMPER THEREFOR - A method of imprinting a microstructure comprising: contacting a stamper comprising a pattern layer with the microstructure of the order of from micrometers to nanometers in one face of the pattern layer and a substrate supporting the pattern layer with an imprinting member having a deformable layer to which the microstructure is imprinted, wherein the pattern layer is supported on a round surface having a prescribed radius of curvature of the substrate, the center of the round surface protruding towards the rear face of the pattern layer; causing the deformable layer on the imprinting member; and separating the stamper from the cured deformable layer. | 10-01-2009 |
20090246309 | FINE STRUCTURE IMPRINTING MACHINE - A fine structure imprinting machine is provided which can surely and easily eliminate static electricity in removing a stamper from an imprinting object. The fine structure imprinting machine is adapted to bring the stamper with a fine concavo-convex pattern formed thereon into contact with the imprinting object, thereby to imprint the fine concavo-convex pattern of the stamper onto a surface of the imprinting object. The stamper has a conductive film on at least a pattern formation surface thereof. The stamper is fixed by a conductive holding member, the conductive film is connected to the holding member via the conductor, and the holding member is connected to a ground within the machine. | 10-01-2009 |
20100062098 | STAMPER FOR MINUTE STRUCTURE TRANSFER AND A METHOD FOR MANUFACTURING THE SAME - The present invention can provide a stamper for minute structure transfer to be excellent in durability. The present invention is characterized by which a minute pattern as formed in one side of a substrate comes in contact with a material to be transferred and the minute pattern is transferred on a resin layer of a surface of the material to be transferred. At least one layer of a thin film is mounted on at least one side of both surfaces of the substrate, the substrate and the thin film are different in a coefficient of linear expansion each other, and the substrate is curved to swell up to be convex in the side of the minute pattern by an internal stress generated in the thin film. | 03-11-2010 |
20100189836 | MICROPATTERN TRANSFER DEVICE - In a micropattern transfer device, a stamper on which a fine indented pattern is formed is brought into contact with a material to be transferred, and the fine indented pattern on the stamper is transferred onto a surface of the material to be transferred. The micropattern transfer device includes a holding mechanism which holds an entire outer circumferential portion of the material to be transferred. The holding mechanism holds the material to be transferred such that a distance between the material to be transferred and the stamper is substantially equal to or shorter than a distance between the holding mechanism and the stamper. | 07-29-2010 |
20100255139 | MICROPATTERN TRANSFER STAMPER AND MICROPATTERN TRANSFER DEVICE - A micropattern transfer stamper has a space that hermetically contains fluid, on an opposite side of a surface with an indented pattern formed thereon of a pattern forming sheet member. The pattern forming sheet member is convexly bent by pressure of the fluid contained in the space. When the indented pattern is transferred onto the material to be transferred, the pattern forming sheet member deforms following the surface of the material to be transferred. | 10-07-2010 |
20120029110 | PHOTOPOLYMERIZABLE RESIN COMPOSITION FOR TRANSFERRING MICROSTRUCTURE - A photopolymerizable resin composition for transferring a microstructure, which allows a thinner and uniform thin film to be formed, a transfer accuracy of extremely smaller microfine pattern to be excellent, and a curing time of the thin film to be shortened, is provided. The photopolymerizable resin composition for transferring a microstructure comprises the following component (A), component (B), component (C), component (D) and component (E) at the rate described below:

20120205838 | DEVICE AND METHOD FOR TRANSFERRING MICRO STRUCTURE - A microstructure transferring device is characterized in that the device comprises a stamper made from a first photo-curable resin composition cured with light with a first wavelength, and a light source emitting light with a second wavelength longer than the first wavelength. The microstructure is transferred to an impression receptor supplied with a second photo-curable resin composition, which is curable with light with the second wavelength emitted by the light source. | 08-16-2012 |
20130011632 | MICROFINE STRUCTURE, METHOD FOR PRODUCING MICROFINE STRUCTURE, AND POLYMERIZABLE RESIN COMPOSITION FOR PRODUCING THE SAME - Provided is a method for producing a microfine structure comprising the steps of: forming a resin film by applying a liquid polymerizable resin composition containing a high molecular weight component, a low molecular weight component and a reactive dilution component to an adhesion promoting layer formed on a substrate; imprinting a mold with an extremely fine convex concave pattern onto the resin film; and transferring the convex concave pattern to the resin film. Herein, components of the adhesion promoting layer, the high molecular weight component, the low molecular weight component and the reactive dilution component respectively have cross-linking reactive functional groups which react with each other. | 01-10-2013 |
