Abstract:
1. A pattern forming apparatus, comprising: a first holder that holds a plate-like object; a second holder, including a flat surface facing the object held by the first holder and a plurality of openings formed in the flat surface, that is adapted to hold a blanket with the flat surface by suction; a positive pressure supplier that supplies a positive pressure to each opening; a negative pressure supplier that supplies a negative pressure to each opening; and a controller that controls the supply of the positive pressure by the positive pressure supplier and the supply of the negative pressure by the negative pressure supplier for each of the openings, wherein the plurality of openings include a first opening and a plurality of second openings, and the plurality of second openings include a third opening adjacent to the first opening; the controller supplies the positive pressure to the first opening to lift a portion of the blanket from the flat surface so that the lifted portion is brought into contact with the object while supplying the negative pressure to the plurality of second openings to hold the blanket by suction; and the controller stops supplying the negative pressure to the third opening so as to widen an area of the blanket brought into contact with the object.
