  • Patent number: 10031429
    Abstract: The present invention provides a method of obtaining a position of a second shot region next to a first shot region, out of a plurality of shot regions formed on a substrate, comprising a first detection step of detecting a position of a first mark arranged in the first shot region, a second detection step of detecting a position of a mark more distant from the first mark, out of a second mark and a third mark arranged in the second shot region, and a determination step of determining the position of the second shot region based on a detection result in the first detection step and a detection result in the second detection step.
    Type: Grant

  • Patent number: 9665018
    Abstract: A measuring apparatus measures a position of each of shot regions formed on a substrate. The apparatus includes a detector configured to detect a mark formed with respect to a shot region on the substrate, and a processor configured to obtain a position of each of the shot regions based on an output of the detector. The processor is configured to obtain a coefficient of a regression equation for obtaining a position of each of the shot regions, based on an output of the detector with respect to each of a plurality of sample shot regions on the substrate, and obtain, if the coefficient satisfies a tolerable condition for a discrepancy between the coefficient and a reference value thereof, the position of each of the shot regions using each offset amount that is obtained beforehand to correct the position of each of the shot regions obtained based on the regression equation.
