Abstract:
PROBLEM TO BE SOLVED: To provide an improved imprint lithography apparatus and a method. SOLUTION: This imprint lithography apparatus includes: an imprint template holder 22 which is constituted in a manner to hold an imprint template 20; and a plurality of position sensors 28 which are constituted in a manner to measure the variation of the size and/or shape of the imprint template 20, and the position sensors 28 are mechanically separated from the imprint template 20. In addition, the imprint template 20 is used in order to imprint a pattern on a board 34, and the variation of the size and/or shape of the imprint template 20 are measured while the pattern is imprinted on the board 34 by this lithography method.

Abstract:
PROBLEM TO BE SOLVED: To provide a novel or substitutional structure suitable for holding, moving or deforming an imprint template structure by being used in an imprint lithography apparatus. SOLUTION: A structure suitable for being used in an imprint lithography apparatus is disclosed. The structure includes: a support structure arranged to support an imprint template structure; a first actuator structured to apply force to the imprint template structure; and a second actuator mounted to the support structure, arranged to extend between the support structure and the imprint template structure in use, structured to apply force to the imprint template structure, and having a movement range larger than that of the first actuator.

Abstract:
PROBLEM TO BE SOLVED: To solve a problem that since template holders occupy a significant amount of space in an imprint lithography apparatus, there is not sufficient space to provide an imprint template to imprint every imprint area at the same time. SOLUTION: The imprint lithography apparatus has a first array of template holders, a second array of template holders, and a substrate table arranged to support a substrate to be imprinted, wherein the first array of template holders is arranged to hold an array of imprint templates that can be used to imprint a first array of patterns onto the substrate, and the second array of template holders is arranged to hold an array of imprint templates that can be used to imprint a second array of patterns onto the substrate, the patterns imprinted by the second array being interspersed between the patterns imprinted by the first array.

Abstract:
PROBLEM TO BE SOLVED: To describe a method for determining the position of a substrate relative to an imprint template. SOLUTION: The imprint template has at least three gratings, the substrate has at least three gratings, positioned such that each imprint template grating forms a composite grating with an associated substrate grating with each imprint template grating, and at least three imprint template gratings and the associated substrate gratings have offsets relative to one another. The method includes steps of detecting an intensity of radiation which is reflected by the three composite gratings; and using the detected intensity to determine a displacement of the substrate or imprint template from a position.

Abstract:
PROBLEM TO BE SOLVED: To provide an imprint lithography device which solves the problem of the shortage of the space for forming imprint templates when imprinting each imprint area at the same time, since a template holder occupies space significantly. SOLUTION: The imprint lithography device comprises a first array of template holders, a second array of template holders, and a substrate table arranged for supporting a substrate to be imprinted. The first array of template holders is arranged for holding an array of imprint templates that can be used for imprinting a first array of patterns onto the substrate. The second array of template holders is arranged for holding an array of imprint templates that can be used for imprinting a second array of patterns onto the substrate. The patterns imprinted by the second array are interspersed between the patterns imprinted by the first array. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
A method of forming at least one lithography feature, the method comprising: providing at least one lithography recess on a substrate, the or each lithography recess comprising side-walls and a base, with the side-walls having a width therebetween; providing a self-assemblable block copolymer having first and second blocks in the or each lithography recess; causing the self-assemblable block copolymer to self-assemble into an ordered layer within the or each lithography recess, the ordered layer comprising at least a first domain of first blocks and a second domain of second blocks; causing the self-assemblable block copolymer to cross-link in a directional manner; and selectively removing the first domain to form lithography features comprised of the second domain within the or each lithography recess.
Abstract:
A method of aligning an imprint template with respect to a target region of a substrate is disclosed, the method including depositing a volume of an imprintable medium within the target region; contacting an imprint template to the imprintable medium so that the imprintable medium is compressed and allowing the imprint template, the target region, or both, to move laterally with respect to each other under interfacial tension forces between the target region and the imprint template, wherein a material which is less wetting than the substrate is provided in a configuration which at least partially surrounds the target region of the substrate.
