An apparatus forms a pattern of an imprint material by curing the imprint material in a state in which the imprint material on a pattern formation region of a member, where a pattern is to be formed, is in contact with a pattern region of a mold. The apparatus includes a dispenser for placing the imprint material on the pattern formation region of the member and a non-pattern formation region of the member, outside the pattern formation region, a detector for detecting the non-pattern formation region in a state in which the imprint material has been placed on the pattern formation region and the non-pattern formation region by the dispenser, and a controller for performing processing for determining an abnormality in the dispenser based on a detection result of the non-pattern formation region by the detector.

A large area patterned film includes a first patterned area; a second patterned area; and a seam joining the first patterned area and the second patterned area, wherein the seam has a width less than about 20 micrometers. A method for tiling patterned areas includes depositing a predetermined thickness of a curable material; contacting a first portion of the curable material with a mold; curing the first portion of the curable material; removing the mold from the cured first portion of the curable material; contacting a second portion of the curable material with the mold, such that the mold contacts a portion of the cured first portion of the curable material; curing the second portion of the curable material; and removing the mold to yield a seam between the cured first portion of the curable material and the cured second portion of the curable material, wherein the seam has a dimension less than about 20 micrometers.

Resin pellets (7) supplied to a resin block forming space (150) are heated and melted by a heater unit (300) and the melted resin pellets (7) are cooled and solidified to form a resin layer. Since a lifting mechanism (230) of a lifting unit (200) lowers a bottom surface plate (215) whenever forming each of the resin layers, the resin layers formed by the resin block forming space (150) are sequentially laminated to form a large resin block.

The present invention provides an imprint apparatus that forms a pattern in an imprint material on a substrate using a mold including a pattern region, the apparatus comprising: a stage configured to be movable while holding the substrate; and a dispenser configured to discharge the imprint material, wherein a sensor, a receptor, and a mark are provided around a holding region where the substrate is held, in an upper surface of the stage, and the upper surface of the stage includes a first region that passes below the pattern region during movement of the stage between a position below the dispenser and a position below the mold, and a second region that does not pass below the pattern region during the movement, and the sensor, the receptor, and the mark are arranged in the second region.
