Abstract: The present disclosure provides an imprint template, including: a base substrate, a pattern layer for imprinting and a planarization layer; wherein the planarization layer is located on a surface of the pattern layer facing away from the base substrate, and a surface of the planarization layer facing away from the base substrate is a plane; and the planarization layer and the pattern layer are configured such that under a specific film removing process, the planarization layer is removed while the pattern layer remains. The present disclosure further provides a preparation method of an imprint template, and an imprint method.

Abstract: The present disclosure generally relates to nanostructure manufacturing. A method for fabricating an imprint template includes providing a first substrate including a first electrode layer on a first base layer and a plurality of first convex portions on a surface of the first electrode layer; providing a second substrate including a second electrode layer on a second base layer, a second resist layer on the second electrode layer, and a plurality of second convex portions on a surface of the second resist layer farthest from the second base layer, supplying electrical signals to the first electrode layer and the second electrode layer to produce an electric field between the plurality of first convex portions and the plurality of second convex portions; and forming the imprint template on the second substrate.

Abstract: An embodiment of this disclosure provides a nano-imprinting method, including: applying an imprinting adhesive on a to-be-processed layer of a substrate located in an imprinting chamber; charging the imprinting chamber with a preset gas at a temperature higher than a boiling point of the preset gas, and pressing a nano-imprinting template on the imprinting adhesive; reducing an ambient temperature of the imprinting chamber to a temperature lower than the boiling point of the preset gas and maintaining the temperature for a preset time, such that the preset gas becomes a liquid; irradiating ultraviolet light from a side of the nano-imprinting template away from the imprinting adhesive to cure the imprinting adhesive; raising the ambient temperature of the imprinting chamber to be higher than the boiling point of the preset gas, such that the liquefied preset gas turns back into a gas; and demolding the nano-imprinting template from the imprinting adhesive.
