摘要:
A stamper is used for the transfer of microscopic structures, the stamper including a base and a microscopic structure layer on a surface thereof, in which the microscopic structure layer has a surface layer including a polymer derived from a resin composition containing a polymerization initiator and a silsesquioxane derivative having two or more polymerizable functional groups, the microscopic structure layer has a modulus of elasticity of less than 2.0 GPa and has a thickness of 4 times or more the height of a microscopic structure formed on the surface of the microscopic structure layer.

A fine-structure transfer apparatus has a base plate, a first post and a second post erected on the upper surface of the base plate, an elongated stamper that is fixed at one end to the upper end face of the first post. The stamper is supported at the other end in a vertically movable manner by means of an ascending/descending unit provided on the second post. A transfer element holding stage is provided on the upper surface of the base plate between the first and second posts in a position that corresponds to the position of the lower surface of the elongated stamper where a fine pattern is formed. A pressure-applying unit is provided to reciprocate on the upper surface of the elongated stamper along a longitudinal direction thereof. The transfer apparatus is characterized by the ease with which the stamper can be detached from the transfer element.

A fine-structure transfer method in which a fine-featured pattern formed on one of the two surfaces of a stamper is pressed against a coating of a resist on one of the two surfaces of a transfer element so as to transfer the fine-featured pattern to the resist coating, wherein the atmosphere in the space between the stamper and the transfer element is replaced by the vapor of the resist before the stamper is pressed against the transfer element.

A method for removing foreign matters attaching on a surface of a fine pattern of a mold, having the fine pattern being convexo-concave, at least on one surface thereof, thereby cleaning the fine pattern surface of the mold, and an imprinting device applying that method therein, without removing, comprises the following steps of: applying a photo-curable resin on a surface of a body to be transcribed, onto which the mold is suppressed, and thereby forming a photo-curable resin layer; suppressing the mold on the photo-curable resin, which is applied on the surface of the body to be transcribed; separating the photo-curable resin cured from the mold, after curing the photo-curable resin, and whereby taking the foreign matters attaching on the surface of the fine pattern into the photo-curable resin cured to remove them, wherein the photo-curable resin to be formed on the surface of the body to be transcribed is formed with such thickness that it can remove the foreign matters attaching on the fine pattern, and also the mold is suppressed onto the photo-curable resin, which is formed on the surface of the body to be transcribed, under such pressure that it can remove the foreign matters attaching on the fine pattern.

The present invention provides an imprinting apparatus or an imprint transfer method in which uniformity of curing quality by UV light is maintained and a uniform application thickness of a UV curable resin is achieved, even if glass is contaminated with dust and/or smudges or has a flaw. A feature of the present invention resides in an imprinting apparatus or an imprint transfer method that, while irradiating an transferred object with energy, transfers a concavo-convex configuration on a stamper's surface onto the transferred object and, subsequently, detaches the stamper from the transferred object, the imprint transfer method including: pressurizing a first reverse surface of at least one of the stamper and the transferred object with a planar pressurizing body having a flat surface configuration; subsequently, pressurizing a second reverse surface of at least one of the stamper and the transferred object with a fluid; and controlling pressurization timing of pressurization by the planar pressurizing body and pressurization by the fluid, thus completing the transfer.
摘要:
In a method for transcripting fine patterns and an apparatus for transcripting fine patterns, the ingress of bubbles is prevented and patterns are transcripted with a high throughput by a relatively compact apparatus. For this purpose, a back surface of a stamper is vacuum sucked and the stamper is brought into close contact with a target of transcription with its surfaces coated with resist and pressure is applied thereto. At this time, the stamper is deformed into a spherical shape or bent to expand the close contact face from a central area to a peripheral area to prevent the ingress of air bubbles into between the target of transcription and the stamper.
