  • Patent number: 10048581
    Abstract: Arrangement information regarding shot areas is obtained in an imprinting method. When a pattern is sequentially formed in the shot areas, the attraction force of a first attraction area is reduced to less than that of the second attraction area. After the pattern is formed in the shot area corresponding to the first attraction area, the attraction forces of the first and second attraction areas are changed. The position information regarding the shot area corresponding to the second attraction area is obtained, which is compared with the position information regarding the shot area corresponding to the second attraction area based on the arrangement information. If the difference between the compared position information is a threshold value or less, positioning of a substrate and a mold is achieved using the arrangement information. If the difference is greater than the threshold value, the arrangement information regarding the shot areas is obtained again.
