摘要: An alignment method of aligning a first object and a second object includes detecting a moire fringe formed by a mark of the first object and a mark of the second object by using a detection unit, detecting an evaluation mark for correcting a detection result of the moire fringe, by the detection unit, and acquiring a detection result of the evaluation mark, determining a relative position of the mark of the first object and the mark of the second object by correcting a detection result of the moire fringe by use of the detection result of the evaluation mark, and aligning the first object and the second object based on the relative position. The evaluation mark is provided in at least one of the first object and the second object.
