  • Patent number: 6552775
    Abstract: An exposure apparatus and a method which make it possible to enhance the fineness of pattern in spite of the trend to enlarge the size of the photosensitive substrate and device. In this apparatus, a mask and the photosensitive substrate are allowed to synchronously scan, and the optical projecting system thereof is provided with a scanning direction adjusting means which is designed to adjust the position of scanning direction of a projected image to be projected onto the substrate, wherein a non-linear component of error is determined in advance and the result thus determined is stored as a correction value for the apparatus, thereby enabling the pattern exposure to be performed while continuously controlling the image-adjusting mechanism on the basis of the correction value.

  • Patent number: 5999244
    Abstract: Positional discrepancies of images of segmental areas, which are caused by stretching of a substrate in the Y direction, are corrected by changing magnifications of respective projection optical systems and inclinations of parallel plane glass pieces with respect optical axes. After that, positional discrepancies of the images after the correction are accurately detected by using a calibration system for the projection optical systems. Thus it is possible to confirm whether or not the positional discrepancies are accurately corrected. If the correction is insufficient as a result of the confirmation, at least one of correction of the magnifications of the respective projection optical systems and shift of the images projected through the respective projection optical systems onto the substrate is executed again so that amounts of the positional discrepancies are sufficiently small.

  • Patent number: 5936712
    Abstract: To improve the focus accuracy during alignment and to improve the alignment accuracy even if a substrate has warpage, during alignment, an approximate focus plane is obtained by using only the detection results at focus points of focus sensors located near the ends of a substrate, close to alignment points, and without using the detection results at focus points of two central focus sensors. The auto-focus operation is performed by using the above operation results. As a result, a substrate is driven so as to be adjusted to the approximate focus plane during alignment.

  • Patent number: RE37762
    Abstract: The present invention is directed to scanning exposure apparatus and exposure method to achieve simultaneous projection of images of plural regions on a mask onto a photosensitive substrate with correcting an orthogonality error of a pattern on the mask or photosensitive substrate. If the pattern on the mask or photosensitive substrate has an orthogonality error causing a deviation of a certain angle in a first direction perpendicular to a scanning direction as it goes in the scanning direction, the mask and the photosensitive substrate are rotated relative to each other in the plane thereof to align one coordinate axis in a coordinate system of each pattern with the first direction.
