  • Patent number: 12253834
    Abstract: There is provided an information processing device determining necessity/non-necessity of adjustment of conditions for inspecting molding defects of a molded composition on a substrate the information processing device including: an image acquiring unit configured to acquire an image of the molded composition; an inspection unit configured to perform inspection of the molding defects from the image using a machine learning model; an information acquiring unit configured to acquire information relating to a molding defect of the composition on a reference substrate; and a determination unit configured to compare an inspection result acquired by inspecting the molding defects on the reference substrate using the inspection unit with the information relating to a molding defect of the composition that is acquired by the information acquiring unit and determine necessity/non-necessity of the adjustment of the conditions of the inspection based on a result of the comparison.

  • Patent number: 9377702
    Abstract: A method of performing patterning of a substrate includes: obtaining, based on first alignment measurement with respect to first patterning, a first compensation value for second alignment measurement, with respect to the first patterning, in which number of alignment marks to be measured is smaller than number of alignment marks to be measured in the first alignment measurement; performing the second alignment measurement with respect to second patterning different from the first patterning; generating, based on a condition with respect to the second patterning and the first compensation value, a second compensation value for the second alignment measurement; and performing the second patterning of a substrate based on the second alignment measurement and the second compensation value.
