Abstract:
1. A substrate processing system for performing predetermined processing on a substrate on which a processing film has been formed, to form a predetermined pattern in the processing film on the substrate, said system comprising: a measuring apparatus for measuring, as an initial condition of the substrate, any of a film thickness of the processing film on the substrate, a refractive index of the processing film, an absorption coefficient of the processing film, and a warpage amount of the substrate; a coating and developing treatment apparatus for performing photolithography processing on the substrate after the measurement of the initial condition in said measuring apparatus, to form a resist pattern on the processing film on the substrate; an etching treatment apparatus for etching the processing film into a predetermined pattern using the resist pattern as a mask; and a control unit having a first relation between the initial condition and a dimension of the pattern of the processing film and a second relation between a processing condition of the predetermined processing and the dimension of the pattern of the processing film, wherein said control unit estimates a dimension of the pattern of the processing film after the etching treatment from the first relation based on a measurement result of the initial condition in said measuring apparatus, and corrects the processing condition of the predetermined processing in the photolithography processing or the etching treatment from the second relation based on an estimation result of the dimension of the pattern.
