Claim 7:
8. A replica mold manufacturing apparatus that manufactures a replica mold which is a replica of a master mold by performing a first imprint process of bringing the master mold into contact with an imprint material on a blank mold to form a pattern of the imprint material, wherein the replica mold manufacturing apparatus is configured to manufacture the replica mold by performing the first imprint process once on a surface of the blank mold, the apparatus comprising:
a receiving unit configured to receive information output from an imprint apparatus that performs a second imprint process of forming a pattern of an imprint material on a shot region of a substrate using the replica mold manufactured by the replica mold manufacturing apparatus, wherein a plurality of shot regions are provided on the substrate and the imprint apparatus is configured to perform the second imprint process on each of the plurality of shot regions on the substrate; and
a controller, including a memory and a processor, configured to set a first imprint condition of the first imprint process to be used in the replica mold manufacturing apparatus based on the information received by the receiving unit,
wherein the information includes information of the pattern formed on the shot region by performing the second imprint process using a second imprint condition set such that an extrusion of the imprint material does not occur from the shot region and an overlay state falls within an allowable range with the imprint apparatus using the replica mold manufactured by performing the first imprint process with the replica mold manufacturing apparatus,
the controller obtains the overlay state between the shot region and the pattern formed on the shot region by performing the second imprint process using the second imprint condition, and
the controller corrects the first imprint condition of the replica mold manufacturing apparatus, to be used in a manufacture of a next replica mold, so that the next replica mold is manufactured in which a difference between a value obtained from the obtained overlay state and a target value of the overlay is reflected and the overlay state falls within an allowable range.
