    • PROBLEM TO BE SOLVED: To provide an alignment apparatus for a substrate bonding system. SOLUTION: A primary optical arm 12a configured so that radiation from primary alignment marks 6a and 6b on a primary substrate 6 may be guided to a detector, and a secondary optical arm 12b configured so that radiation from secondary alignment marks 8a and 8b on a secondary substrate 8 may be guided to a detector 28a are arranged. The primary alignment mark has a known position against a functional pattern arranged on the opposite side of the primary substrate, while the secondary alignment mark has a known position against a functional pattern arranged on the opposite side of the secondary substrate. In addition, the substrate bonding system has primary and secondary substrate tables 4 that are configured so that the primary and secondary substrates may be held, and at least one of the substrate tables can move in response to a signal output from the detector. The primary and secondary substrates can be aligned against each other for bonding. COPYRIGHT: (C)2008,JPO&INPIT

    • PROBLEM TO BE SOLVED: To improve coarse alignment accuracy of a substrate.
      SOLUTION: In a method for alignment of a substrate, the substrate includes a mark in a scribe lane, and the scribe lane extends along a longitudinal direction as a first direction. The mark has a periodic structure in the first direction. The method includes: providing an illumination beam for scanning the mark in a direction perpendicular to a direction of the mark's periodic structure along a first scan path across the mark; and scanning the spot of the illumination beam along a second scan path across the mark, wherein the second scan path is parallel to the first scan path, and the second scan path is shifted relative to the first scan path over a first shift that corresponds to a fraction of the repeating distance of the periodic structure.
