  • Patent number: 12142502
    Abstract: A processing condition selection method includes a step (S21) and a step (S22). In the step (S21), a thickness pattern TM that represents a distribution of thicknesses measured at respective measurement points on a target is compared to pre-stored reference patterns (RP) to specify a reference pattern (RP) having a high correlation with the thickness pattern (TM) from among the reference patterns (RP) based on a prescriptive rule. In the step (S22), a reference processing condition associated with the specified reference pattern (RP) is acquired as a processing condition for the target from among reference processing conditions associated with the respective reference patterns (RP). The reference patterns (RP) each represent a distribution of physical quantities of a corresponding one of reference targets.

  • Publication number: 20240203765
    Abstract: A substrate processing apparatus, a substrate processing system, and a data processing method are provided. A substrate processing apparatus (100) includes a thickness gauge (8), a controller (102), and storage (103). The thickness gauge (8) measures the thickness of an object (TG) included in a substrate (W). The controller (102) enters input data in a trained model (LM), thereby causing the trained model (LM) to output processing conditions. The storage (103) stores reference data (RE) acquired based on pieces of training data (LD) used to construct the trained model (LM). The controller (102) acquires pre-processing measurement data indicating the thickness of the object (TG) before the substrate processing is performed, and creates input data based on target data indicating a target value for the thickness of the object (TG) and the pre-processing measurement data. The controller (102) compares the input data and the reference data (RE) to determine whether or not to perform the substrate processing.
