Patent ID: 8367308

Claim:
A substrate processing method for processing a substrate, the method comprising: a first process of forming a first resist pattern by exposing the substrate having thereon a first resist film to lights, developing the exposed substrate and cleaning the developed substrate; and a second process of forming a second resist pattern by forming a second resist film on the substrate having thereon the first resist pattern, exposing the substrate having thereon the second resist film to lights, and developing the exposed substrate, wherein, a first processing condition is determined based on first data showing a relationship between a first processing condition under which a cleaning process is performed on the substrate in the first process and a line width of the second resist pattern, the first process is performed on the substrate under the determined first processing condition, the first processing condition includes a processing time for performing the cleaning process on the substrate, the first data include a convergence time when line widths of the second resist pattern converge to a constant value, and the processing time is determined so as to be substantially the same as the convergence time based on the first data.
