Abstract:
1. An imprint system comprising: a moving mechanism for moving an imprint head having a template to a separation direction at a separation force; and a chucking mechanism for retaining a substrate to a predetermined position on a stage at a predetermined chucking force, wherein the imprint system firstly transfers a pattern of the template to an imprinting layer between the template and the substrate and then moves the imprint head to the separation direction to leave the imprinting layer having the transferred pattern on the substrate, wherein the chucking mechanism includes a plurality of chucking sections respectively connecting to a pressure control device to generate individual chucking forces, and wherein the plurality of chucking sections are formed of a plurality of first pins and a plurality of channels, each of the first pins and the channels connecting to the pressure control device, and wherein the individual chucking forces of one or more of the plurality of chucking sections are varied by the pressure control device while the imprint head is moved to the separation direction, whereby a magnitude of the separation force is reduced.
