    摘要: In an alignment method for effecting alignment between two plate-like objects, a first plate-like object provided with a first alignment mark and a second plate-like object provide with a second alignment mark are disposed opposite to each other. A first area and a second area are provided at mutually nonoverlapping positions in an image pickup area for being observed through an image pickup device. Images of the first and second alignment marks are picked up by the image pickup device from a direction substantially perpendicular to an in-plane direction of the first and second plate-like objects. Alignment control is effected by using first information about a deviation of the first alignment mark from a predetermined position in the first area and second information about a deviation of the second alignment mark from a predetermined position in the second area.

    摘要: An imprint apparatus for performing alignment between a mold and a substrate and imprinting a pattern of the mold to a layer of the substrate. A holder holds the mold. A stage holds the substrate opposite to the mold held by the holder. A microscope, including an image pickup device, detects a first alignment mark formed in the mold, via a first image pickup area of the image pickup device, and detects a second alignment mark formed in the substrate, via a second image pickup area of the image pickup device. The first and second image pickup areas do not overlap with each other. A contrast of signals obtained by the image pickup device is adjusted with respect to each of the first and second image pickup areas, and the alignment is performed by changing relative positions of the holder and the stage based on first information about a deviation of the detected first alignment mark from a predetermined position in the first image pickup area and second information about a deviation of the detected second alignment mark from a predetermined position in the second image pickup area.

    摘要: A pattern transfer apparatus transfers an imprint pattern formed on a mold, provided with an alignment mark, to a resin material on a substrate, provided with an alignment mark. A first image pickup device obtains an image of an object positioned at a first object position. A second image pickup device obtains an image of an object positioned at a second object position. The second object position is more distant from the alignment mark of the mold than the first object position. An optical system forms an image of an object positioned at the first object position and an image of an object positioned at the second object position. Alignment is performed based on first and second information obtained about positions of images of an alignment mark of a reference substrate and an alignment mark of the substrate, to transfer the imprinting pattern to the resin material.
