  • Patent number: 7924426
    Abstract: A shape measuring apparatus for measuring the shape of a measurement target surface includes an interferometer and computer. The interferometer senses interference light formed by measurement light from the measurement target surface and reference light by a photoelectric converter, while changing the light path length of the measurement light or the reference light. The computer Fourier-transforms a first interference signal sensed by the photoelectric converter to obtain a phase distribution and an amplitude distribution, shapes the amplitude distribution, inversely Fourier-transforms the phase distribution and the shaped amplitude distribution to obtain a second interference signal, and determines the shape of the measurement target surface based on the second interference signal.

  • Patent number: 7884935
    Abstract: 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.
