Abstract:
1. An alignment information display method for displaying information relating to alignment measurement for positioning an object, comprising the steps of: inputting data of results of predetermined processing relating to the alignment measurement, the data of results of predetermined processing relating to the alignment measurement including data of EGA measurement results measured by an exposure apparatus and data of overlay measurements results measured by an overlay measuring device, inputting information relating to a parameter of the alignment measurement, finding desired information for display from data of the input data of results of predetermined processing relating to the alignment measurement based on the parameter of the alignment measurement, receiving input of an evaluation target of a plurality of evaluation targets, the plurality of evaluation targets including at least one of an alignment measurement value, an alignment correction value, a residual component after alignment correction, and an alignment mark waveform, receiving input of a display unit of a plurality of display units, the plurality of display units including information to be displayed about at least one of each predetermined plurality of lots, each single lot, each predetermined plurality of wafers, each single wafer, each plurality of shots processed, each single shot, each predetermined plurality of marks, and each single mark, designating a desired display mode of a plurality of display modes, the plurality of display modes including at least one of a numerical data display, vector data display, histogram-scatter diagram, trend graph or other statistical display, sort result display, and waveform data display, and displaying the found desired information for display in the desired display mode showing effects of the parameter of the alignment measurement on the alignment measurement, wherein the found desired information for display is displayed in each of the received display unit of the plurality of display units by the desired display mode of the plurality of display modes during the step of displaying so as to enable evaluation of the received evaluation target, and the displaying comprises displaying the shown effects in each received display unit of the plurality of display units using the same parameter, the shown effect being achieved by displaying a plurality of displays, each display representing a respective different display unit.
