  • Publication number: 20110222037
    Abstract: An exposure apparatus comprises a liquid immersion system, a first mover, and a prescribed member. The exposure apparatus exposes a substrate via an optical member and a liquid. The liquid immersion system performs supply and recovery of the liquid. The first mover can move in a first area, and can hold the liquid between itself and the optical member. The prescribed member is removed from the first mover when the first mover withdraws from a position opposing the optical member, and can hold the liquid between itself and the optical member.

  • Publication number: 20110013162
    Abstract: When a segmented region SAi of a sheet S is scan-exposed, a stage SST1 adsorbs, at a standby position at the +X end portion of a scan region AS, a rear surface portion corresponding to the segmented region SAi of the sheet S onto a holding surface of a sheet holder SH1, and moves in the X axis direction (the ?X direction) with a predetermined stroke in synchronization with a mask (a mask stage). At this time, illumination beams corresponding to the parts of a pattern of the mask are irradiated onto the sheet S via projection optical systems. Thereby, the pattern is transferred (formed). After scan-exposure on the segmented region SAi, a stage SST2 moves to a standby position within the XY plane. After the stage SST2 adsorbs a rear surface portion corresponding to the next segmented region SAi+1 of the sheet S onto a holding surface of a sheet holder SH1, an exposure is performed by the scan-exposure method similarly to the above, to thereby form the pattern.

  • Publication number: 20110012294
    Abstract: Six auxiliary sheet holders SH2 and SH3 temporarily holding a sheet S are minutely driven in the ?Z-axis direction by a control device so that holding surfaces thereof are positioned on the slightly lower side (?Z side) of the holding surface of the sheet holder SH1. Accordingly, an appropriate tension is applied to the sheet S in the width direction (Y-axis direction) and the longitudinal direction, so that the center portion of the sheet S is fixed onto the holding surface of the sheet holder SH1. That is, in the state where an XY two-dimensional tension is applied to a separate area SAi of the sheet S, a rear surface portion corresponding to the separate area SAi of the sheet S is changed in accordance with the flat shape of the holding surface of the sheet holder SH1.

  • Publication number: 20090263736
    Abstract: A pattern image generation device generates a pattern image, and at least a part of the pattern image which has been generated or the pattern image which is generated and is formed on an object is photoelectrically detected by a detection system. Then, a correction device corrects design data that should be input to the pattern image generation device based on the detection results. Accordingly, a pattern image is generated on an object by the pattern image generation device corresponding to the input of the design data after the correction, and because the object is exposed using the pattern image, a desired pattern is formed on the object with good precision.
