An alignment method for aligning two substrates to be stacked, comprising measuring a position of a mark selected from plurality of marks disposed on at least one substrate of the two substrates and aligning the two substrates based on the position of the measured mark, wherein the mark to be measured is selected based on information relating to distortion of the at least one substrate. The mark may be a mark disposed in a region having a smaller distortion amount of the at least one substrate than a threshold. The mark may be a mark disposed in a region having a higher reproducibility of distortion that occurs in the at least one substrate than a threshold.

Alignment method and alignment apparatus
