According to one embodiment, first image information of a mold is acquired by irradiating the mold with first light, the mold having an uneven pattern with a shape corresponding to a pattern to be transferred onto a substrate to be processed. The position of the uneven pattern of the mold is adjusted by applying stress to the mold. Second image information is acquired by irradiating the mold whose position is adjusted with the first light. Stress information of the mold whose position is adjusted is measured by comparing the first image information with the second image information. The position adjustment is repeated until the measurement result satisfies a desired condition, and a pattern is formed on the substrate by using the mold whose position is adjusted.

According to one embodiment, a pattern forming method for imprinting an imprinting surface having recess and protrusion of a template onto an imprint material provided on a target substrate is disclosed. The method includes filling a recess portion of the recess and protrusion with the imprint material. A photo-deformable layer is interposed between at least one of a location between the imprinting surface and the imprint material and a location between the target substrate and the imprint material during the filling. A configuration of the photo-deformable layer is deformable by light irradiation. The method includes curing the imprint material while the recess portion is filled with the imprint material. The method includes releasing the cured imprint material from the imprinting surface by irradiating the photo-deformable layer with light and by deforming the photo-deformable layer. The light has an intensity varying within a plane parallel to the imprinting surface.

In one embodiment, an imprint apparatus includes a template holding part configured to hold a template for imprint. The apparatus further includes a template moving part configured to move the template to press the template onto a light curing resin on a transfer target substrate or to demold the template from the light curing resin. The apparatus further includes a light source configured to irradiate the light curing resin with light to cure the light curing resin. The apparatus further includes a demold control part configured to control a demold speed or a demold angle of the template, based on a position of a shot region from which the template is to be demolded, when demolding the template from the light curing resin.

In an imprint method according to embodiments, light that hardens a resist is irradiated to a light irradiation region near an alignment mark in order to prevent the resist from being filled in the alignment mark of a template, when the alignment process between the template and a substrate is performed. After the alignment process is completed, the resist is filled in the template pattern and the alignment mark, and then, light that hardens the resist is irradiated onto the template.

In an imprint method according to one embodiment, a template on which a template pattern is formed is pushed against resist on a substrate to be transferred while the resist is cured in this state. The template is subsequently separated from the cured resist. The template is then degassed from the template pattern surface side between after the template is separated from the cured resist and till the template is pushed against resist at the next shot.
