Patent ID: 7531821

Claim:
An imprint apparatus, comprising: a first holder for holding a mold having an imprint pattern; a second holder arranged in opposition to the mold for holding a workpiece to which the imprint pattern is transferred; a first illumination system for irradiating a mark for determining a position of the mold and a mark for determining a position of the workpiece with light; a first optical system for imaging the mark for determining the position of the mold at a first observation point by using the light from the first illumination system; a second optical system for imaging the mark for determining the position of the workpiece at a second observation point; an imaging optical system that belongs to both the first optical system and the second optical system; a first image pick-up device for observing the mark for determining the position of the mold which is imaged at the first observation point; a second image pick-up device for observing the mark for determining the position of the workpiece which is imaged at the second observation point; and at least one drive mechanism of a first drive mechanism for moving the first image pick-up device while following movement of the first observation point which is caused by a change in distance between the mold and the imaging optical system and a second drive mechanism for moving the second image pick-up device while following movement of the second observation point which is caused by a change in distance between the workpiece and the imaging optical system.
