  • Patent number: 7868997
    Abstract: In the inspection apparatus of this projection optical system, a folding glass member, comprising a flat surface part and a reflecting spherical surface part opposing to the flat surface part, is disposed on the image plane side of the projection optical system so that the flat surface part opposes to the projection optical system. Further, in a state wherein a liquid is supplied between the projection optical system and the folding glass member, a measuring beam emitted from an interferometer unit enters the projection optical system; the measuring beam that transmitted through the projection optical system and the liquid, and entered the folding glass member is reflected by the reflecting spherical surface part, and once again passes through the liquid and the projection optical system; and the interference fringes obtained from the measuring beam and the reference beam generated within the interferometer unit are detected.

  • Publication number: 20090011368
    Abstract: An object is to provide a high-resolution and economical exposure method suitable for use in formation of a fine pattern for making up an electronic device. Two diffraction gratings (P1, P2) are located in series in an optical path; the two diffraction gratings (P1, P2) and a wafer or the like (W) for making up an electronic device are arranged with a predetermined spacing; a light-dark pattern of interference fringes generated by the diffraction gratings (P1, P2) is transferred onto the wafer or the like (W) to effect exposure. The exposure is done while changing a positional relation between the wafer or the like (W) and the diffraction gratings (P1, P2) according to need.

  • Patent number: 6963408
    Abstract: A point diffraction interference measuring method comprises forming a substantially ideal spherical wave by using a point light source-generating unit 101, 102, allowing a light flux composed of the spherical wave to pass through a test sample 109, thereafter dividing the light flux into two light fluxes by using an optical path-dividing element 105, allowing one light flux of the divided light fluxes to pass through a pinhole 129 to covert the one light flux into a reference light beam which is a substantially ideal spherical wave, and detecting interference fringes generated by causing interference between the reference light beam and a measuring light beam which is the other light flux of the divided light fluxes. The wavefront aberration of the test sample can be measured by observing the interference fringes without being affected by the disturbance which would be otherwise caused by any system vibration or the like.

  • Patent number: 6894763
    Abstract: A mask stage RS1 and a substrate stage WS1 are synchronously moved, and a mask stage RS2 and a substrate stage RS2 are synchronously moved, in a state in which a mask on the mask stage RS1 and a mask on the mask stage RS2 are irradiated with illumination light beams from illumination optical systems IOP1, IOP2 respectively. The reaction force on a base board due to the movement of the stages can be canceled to suppress the vibration of an exposure apparatus by moving the mask stage RS1 and the mask stage RS2 in mutually opposite directions. The throughput can be improved by performing alignment operation on substrate stages WS3, WS4 concurrently with the exposure operation.
