In the present invention, photolithography processing is performed on a substrate to form a resist pattern over the substrate, and a treatment agent is caused to enter a side surface of the resist pattern and metal is caused to infiltrate the side surface of the resist pattern via the treatment agent, the formed resist pattern has a high etching selection ratio with respect to a film to be treated on the substrate so as to suppress a so-called pattern collapse, therefore. |
