  • Patent number: 6558852
    Abstract: An exposure method forms, in a shot area on a reticle, marks to measure arrangement errors that may occur between adjacent device patterns, transfers the marks from the reticle onto a wafer through exposure and development processes using an exposure system, measures arrangement errors according to the marks on the wafer, calculates four error components from the measured arrangement errors, and corrects the exposure system according to the calculated error components. This method eliminates superposition errors from the next exposure process, thereby effectively using the shot areas of exposure systems.

  • Patent number: 6437858
    Abstract: A plurality of bars-in-bars marks are formed. Each mark has four small patterns and four large patterns arranged in a direction of a straight line and a direction perpendicular thereto. The straight lines of the respective bars-in-bars marks are disposed at angles of 0°, 30° and 60°.

  • Patent number: 6163376
    Abstract: In an alignment apparatus, an alignment mark formed on a substrate is illuminated through an illuminating optical system, and an image of the alignment mark is projected onto a light receiving surface of a CCD camera through an enlarging optical system. The enlarging optical system includes a parallel flat plate, the inclination of which can be adjustable, for parallel-translating an eccentric component of coma.
