Abstract:
1. An imprint method comprising: acquiring first image information of a mold by irradiating the mold with first light and receiving the first light reflecting a polarization characteristic of the mold, the mold having an uneven pattern with a shape corresponding to a pattern to be transferred onto a substrate to be processed; adjusting a position of the uneven pattern of the mold by applying stress to the mold; acquiring second image information by irradiating the mold whose position is adjusted with the first light and receiving the first light reflecting a polarization characteristic of the mold whose position is adjusted; measuring stress information of the mold whose position is adjusted, by comparing the first image information with the second image information; and repeating the position adjustment until the measurement result satisfies a desired condition, and forming a pattern on the substrate by using the mold whose position is adjusted.
