Abstract:
According to an embodiment, a method for forming a pattern includes selectively forming a first film on a first region on a substrate. The first region is included in an optical interference area of a first light and a second light on the substrate. The first light passes through a first passing portion of a diffraction mask and the second light passes through a second passing portion of the diffraction mask. The method further includes exposing the first film to optical interference light generated by at least the first light and the second light.

According to one embodiment, a pattern formation device that presses a template that includes a concave and convex part onto a transferring object and that forms a pattern in which a shape of the concave and convex part is transferred is provided. The device includes: a calculation part; an adjustment part; and a transfer. The calculation part calculates, using design information of the pattern, the distribution of force applied to the pattern at a time of releasing the template pressed onto the transferring object from the transferring object. The adjustment part adjusts forming conditions of the pattern in order to uniformly approach the distribution of force calculated by the calculation part. The transfer part transfers the shape of the concave and convex part to the transferring object according to the forming conditions adjusted by the adjustment part.

According to one embodiment, a pattern data generation method includes: decomposing data of a pattern to be formed into first guide pattern data and first DSA pattern data; generating a plurality of combinations of second guide pattern data and second DSA pattern data based on combinations of the first guide pattern data and the first DSA pattern data; carrying out simulation for each of the plurality of combinations of the second guide pattern data and the second DSA pattern data, and evaluating the simulation results using a predetermined evaluation function; and extracting one set or a plurality of sets of combinations that are suitable for forming the pattern to be formed, from among the plurality of combinations of the second guide pattern data and the second DSA pattern data, based on the evaluation results.
Abstract:
According to one embodiment, a mold includes a base, a first concave pattern, a second concave pattern, and a third concave pattern. The base includes a first surface and a pedestal projecting from the first surface. The pedestal includes a first region and a second region disposed outside the first region. The first concave pattern is formed in the first region. The second concave pattern is formed in the second region. The third concave pattern extends from the first region to the second region.
Abstract:
According to one embodiment, a pattern data creating method includes a calculation process, a determination process, and a correction process. In the calculation process, it is calculated a stress distribution of stresses that are applied to a template when a distance between the template and a substrate on which resist are disposed is predetermined, the template including a template pattern. In the determination process, it is determined whether or not there is a stress concentration spot in the template pattern at which a stress value larger than a predetermined criterion value is to appear. If the stress concentration spot is present, in the correction process, it is a corrected pattern data of the template pattern such that the stress value at the stress concentration spot becomes a stress value not larger than the predetermined criterion value.
Abstract:
According to one embodiment, a mold manufacturing method includes obtaining a first distribution, obtaining a second distribution, generating a correction data, and forming a second mold. The first distribution is a distribution of level difference included in a first layer on a substrate. The obtaining the second distribution obtains the second distribution when a first mold having the concave-convex pattern is brought into contact with a photosensitive resin applied on the first layer and the resin is cured. The second distribution is a distribution of film thickness of the resin remaining between the substrate and a convex pattern feature of a concave-convex pattern. The correction data is a data for suppressing a difference between one of the first distribution and the second distribution, and a film thickness of a reference set beforehand. The second mold is different from the first mold using the correction data.
