Abstract

A processing condition selection method includes a step (S) and a step (S). In the step (S), 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 (S), 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. The reference processing conditions each are a processing condition when processing is previously performed on a corresponding one of the reference targets with a corresponding one of the reference patterns (RP).
