Abstract

According to one embodiment, a sliding inhibition portion extracting method is applied to pattern formation to press an original having a pattern against a resin on a transferred object and cure the resin to transfer the pattern of the original, and extracts a sliding inhibition portion that inhibits sliding of the original in a state of being in contact with the resin before curing in a shot region that is a region in which the pattern is formed by single transfer by either a first technique of estimating the sliding inhibition portion on the basis of at least one of an uneven distribution on a surface of the transferred object, a pattern layout of the original, and a result of misalignment of a transfer pattern, changing a thickness of the resin in the shot region on the basis of the estimation, and determining whether sliding inhibition of the original occurs, or a second technique using a table indicating a relationship between a distribution of the sliding inhibition portion in the shot region and the misalignment of a transfer pattern.
