Patent
Scivax Corporation | Date: 2013-01-11

A shaping method and a shaping device are provided which can easily and inexpensively form a curved face in a film including a micropattern. A shaping method is for forming, in a predetermined shaping-target area of a film including a patterned face with a micropattern, and a rear face opposite to the patterned face, a curved face beyond the thickness of the film, and includes a fixing step for fixing an outer edge of the shaping-target area of the film by fixing means, a first heating step for heating the film


Patent
Scivax Corporation and Maruzen Petrochemical Co. | Date: 2014-08-01

A cyclic-olefin-based thermoplastic resin for thermal imprint to be used in the production of a sheet or a film which contains at least one of skeletons represented by the following chemical equation 1 or the following chemical equation 2 in a main chain. The glass transition temperature Tg ( C.) and the value ([M]) of MFR at 260 C. satisfy the following equation 1, and [M]<30. The thermal imprint characteristics (transferability, mold release characteristic, and the like) are superior and the productivity (throughput) is improved.

Scivax Corporation | Date: 2013-06-19

A roller-type depressing device, an imprint device and an imprint method utilizing the same which can depress an object like a die or a molding target by controlling the depressing force of a roller is provided. A roller-type depressing device to depress the object with a roller includes a pressure adjusting plate provided with the roller, a roller moving unit moving the roller relative to the object, a pressure adjusting unit holding the pressure adjusting plate in such a way that force produced by a pressure difference in fluid applied to both faces of the pressure adjusting plate acts on the roller, a pressure receiving stage receiving the pressure of the roller via the object, and a pressure adjuster adjusting the pressure difference in fluid applied to both faces of the pressure adjusting plate.

A resin for thermal imprint include a cyclic-olefin-based thermoplastic resin that contains at least one of skeletons represented by the following chemical equation 1 or the following chemical equation 2 in a main chain. The glass transition temperature Tg ( C.) and the value ([M]) of MFR at 260 C. satisfy the following equation 1, and [M]>10. The thermal imprint characteristics (transferability, mold release characteristic, and the like) are superior and the productivity (throughput) is improved. Tg( C.)<219log [M]104[Equation 1]

The present invention provides an imprinting device and an imprinting method which can uniformly apply pressure between a mold and a molding object and which can increase and decrease a temperature at a fast speed. An imprinting device is for transferring a pattern on a mold to a film molding object, and comprises a stage for holding the mold, a pressurizing-chamber casing which configures a pressurizing-chamber together with the molding object, sealing means which airtightly seals a space between the pressurizing-chamber casing and the molding object, opening and closing means which opens and closes the space between the pressurizing-chamber casing and the molding object, pressurizing means which adjusts atmospheric pressure in the pressurizing-chamber, heating means which heats either one of or both of the mold and the molding object, and degassing means which eliminates any gas present between the mold and the molding object.
