Title:
METHOD FOR PROCESSING SUBSTRATE AND APPARATUS FOR PROCESSING SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2005/109476
Kind Code:
A1
Abstract:
It is aimed to improve the etching resistance of a resist pattern prepared for dealing with exposure light sources of short wavelengths. Specifically, after forming a resist pattern by exposing and developing a resist film on a substrate, a treatment is conducted by supplying a fluorine-containing liquid onto the surface of the resist pattern. A foundation film is then etched using the thus-treated resist pattern as a mask. By being subjected to such a treatment, the density of fluorine molecules is increased in the surface of the resist pattern, thereby improving the etching resistance of the resist pattern.
