Abstract:
1. A substrate processing method of 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 method comprising: a first step of 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 second step of estimating a dimension of the pattern of the processing film after the predetermined processing from a previously obtained first relation between the initial condition and the dimension of the pattern of the processing film based on a measurement result of the initial condition; a third step of obtaining a correction value for a processing condition of the predetermined processing from a previously obtained second relation between the processing condition of the predetermined processing and the dimension of the pattern of the processing film based on an estimation result of the dimension of the pattern; a fourth step of correcting the processing condition of the predetermined processing based on the correction value; and a fifth step of performing predetermined processing on the substrate under the corrected processing condition to form the predetermined pattern in the processing film on the substrate.
