  • Publication number: 20240087925
    Abstract: An information processing apparatus includes a data acquisition unit, a simulation execution unit, and an optimization unit. The data acquisition unit acquires execution result data including an execution result of the substrate processing based on a process parameter including a pressure in the substrate processing apparatus and including sensor data of the pressure in the substrate processing apparatus. The simulation execution unit inputs the execution result data into a simulation model pre-stored in a storage to calculate a pressure in the substrate processing apparatus that is predicted to approach a target value for a substrate processing result. The optimization unit calculates a predicted value of the substrate processing result based on the process parameter including the calculated pressure.
