Abstract
An imprint method includes, in the peeling step of peeling a mold off the material layer to be transferred, a region-of-contact recognition operation of recognizing and determining a region of contact of the mold with the material layer to be transferred, a center-of-gravity locating operation of determining a center of gravity of a morphology of the thus recognized region of contact on the basis of that morphology, and a peeling operation of determining a point of force for applying peeling force to the mold or the imprinting substrate in relation to the center of gravity determined by the center-of-gravity locating operation, thereby acting the peeling force on the point of force.
Claims1
An imprint apparatus, comprising:
- a mold holder for holding a mold in place,
- a substrate holder for holding an imprinting substrate in place,
- a region-of-contact measuring instrument for recognizing and determining a region of contact of the mold with a material layer to be transferred that is interposed between a surface of the mold having an concavo-convex structure region and the imprinting substrate, and
- a data processing unit operable to execute computation and command tasks for controlling a state of the mold being peeled off the material layer to be transferred,
- wherein:
- the data processing unit comprises a center-of-gravity computation portion for determining a center of gravity of a morphology of the region of contact recognized by the region-of-contact measuring instrument in a state where the mold and the material layer to be transferred are in contact with each other, and a point-of-force computation portion for determining a point of force for applying peeling force to the mold or the imprinting substrate, and
- the mold holder or the substrate holder includes a peeler, wherein the peeler is operable to apply the peeling force to the point of force.
