  • Patent number: 11131935
    Abstract: An information processing apparatus outputs correction data using a first system that outputs the correction data for correcting a condition defining processing to be performed in a lithography apparatus that forms a pattern onto a substrate. The first system includes a first model that outputs the correction data in case where a processing result indicating a result of the processing is input, and a second model that outputs the processing result in case where the condition is input. The first system corrects the condition using the correction data output from the first model, and outputs the correction data based on the processing result output by inputting the corrected condition to the second model.
