Abstract
An imprint apparatus forms a pattern of an imprint material on a substrate by using a mold. A substrate holding unit holds the substrate by a suction force between the substrate and a holding surface and includes a first suction unit for sucking a rear surface of a first region of the substrate with a first suction force and a second suction unit for sucking a rear surface of a second region of the substrate with a second suction force. A deformation mechanism deforms a shape of the first region in a direction along the holding surface when forming the pattern of the imprint material on the first region. An adjusting unit adjusts the first and second suction forces. The first suction force is less than the second in at least a portion of a period during the deforming of the shape of the first region by the deformation mechanism.
