Claim:
1. An imprint apparatus for bringing a mold, having a first mark, a third mark, and a pattern region in which a pattern is formed, into contact with an imprint material on a substrate having a second mark and a fourth mark, to form a pattern of the imprint material, the apparatus comprising: a deforming mechanism configured to deform the mold such that a first portion of the mold where the first mark is formed protrudes toward the substrate; a driving mechanism configured to adjust a distance between the mold and the substrate such that the mold and the imprint material on the substrate come in contact with each other; a detecting unit configured to detect, after the driving mechanism starts an operation of adjusting the distance such that the mold and the imprint material on the substrate come in contact with each other, the first mark and the second mark in a state in which the first portion of the mold where the first mark is formed and the imprint material on the substrate are in contact with each other but a whole of the pattern region is not in contact with the imprint material; and a control unit configured to control a relative position of the mold and the substrate based on a detecting result of the first mark and the second mark, wherein the detecting unit includes a photoelectric conversion device, an optical system, and an imaging optical system placed between the photoelectric conversion device and the optical system, wherein the imaging optical system illuminates the substrate through the optical system so as to form, on the photoelectric conversion device, images of intermediate images of the first mark and the second mark, the intermediate images being formed at a position between the optical system and the imaging optical system with light from the substrate, wherein the first mark and the second mark are formed in respective first portions of the mold and the substrate, wherein the third mark and the fourth mark are formed in respective second portions of the mold and the substrate, wherein the respective second portions of the mold and the substrate come in contact with each other after the respective first portions of the mold and the substrate come in contact with each other, wherein the detecting unit is configured to detect the third mark and the fourth mark after detecting the first mark and the second mark, and wherein the control unit is configured to control the relative position of the mold and the substrate based on a detecting result of the third mark and the fourth mark, after controlling the relative position of the mold and the substrate based on the detecting result of the first mark and the second mark.
