  • Patent number: 7674104
    Abstract: A molding apparatus for patterning a workpiece includes a mold having a pattern to be transferred to the workpiece, with the pattern including recesses, a first support member for supporting the mold, and a second support member, arranged opposite to the first support member, for supporting the workpiece. A pressing mechanism brings the first and second support members close to each other and presses the mold and the workpiece together so as to transfer, to the workpiece, the pattern on the mold. Recessed portions are provided on at least one of a surface of the mold on the first support member side, a region of the first support member, and a region of the second support member. The recessed portions correspond to recesses in the pattern of the mold.

  • Publication number: 20090283938
    Abstract: An imprint apparatus for imprinting a mold pattern onto a substrate or a member on the substrate includes a light source for irradiating a surface of the mold disposed opposite to the substrate and a surface of the substrate with light; an optical system for guiding the light from the light source to the surface of the mold and the surface of the substrate and guiding reflected lights from these surfaces to a spectroscope; a spectroscope for dispersing the reflected lights guided by the optical system into a spectrum; and an analyzer for analyzing a distance between the surface of the mold and the surface of the substrate. The analyzer calculates the distance between the surface of the mold and the surface of the substrate by measuring a distance between the surface of the mold and a surface formed at a position away from the surface of the mold.

  • Publication number: 20090108483
    Abstract: 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.
