Abstract:
1. An imprint device which presses a stamper having a concavo-convex pattern against a transferred object and which thus transfers the concavo-convex pattern of the stamper to the transferred object, the imprint device comprising: a light irradiation mechanism for irradiating at least an edge of the transferred object with light, the light irradiation mechanism being installed in the back direction of either one of the transferred object or the stamper; a light detection mechanism for detecting a light that is irradiated from the light irradiation mechanism to an edge of the transferred object, the light detection mechanism being installed in the back direction of the other one of the transferred object or the stamper; a position detector that detects an edge position of the transferred object based on a detection result of the light detection mechanism and calculates a position of an arbitrary point on the transferred object from the edge position; and a positioning mechanism that adjusts a relative position between the transferred object and the stamper from the position information detected by the position detector, wherein the light irradiation mechanism simultaneously irradiates an edge of the transferred object, and an alignment mark formed in the stamper or an edge of the stamper, with light, wherein the light detection mechanism detects an intensity of transmitted light at the edge of the transferred object, and at the alignment mark formed in the stamper or at the edge of the stamper, on the basis of the irradiation light from the light irradiation mechanism, and wherein the position detector detects the edge position of the transferred object, and a position of the alignment mark of the stamper or an edge position of the stamper, from a difference in the intensity of transmitted light detected by the light detection mechanism.
