Abstract:
1. An imprint apparatus for causing a mold to contact a resin disposed on a substrate so as to form a resin pattern on the substrate, the apparatus comprising: a driving device configured to move the mold and the substrate relatively so as to apply a pressing force between the mold and resin; a measuring device configured to measure a position of at least one of the mold and the substrate in a direction in which the driving device moves the mold and substrate relatively to apply the pressing force; a detector configured to detect the pressing force; and a controller configured to control the driving device, wherein the controller is configured to switch from a position control operating during a first time period based on the measured position to a load control operating during a second time period based on the detected pressing force, the first time period ending immediately before the mold comes into contact with the resin, the second time period continuing through contact between the mold and resin, and the load control configured to limit a controller output to the driving device so as not to exceed a predetermined limit during the second period and so that a relative speed between the mold and substrate in the direction in which the driving device moves the mold and substrate relatively is lowered as a result of said switching to not be greater than a predetermined relative speed limit.
