Title: Pattern forming process and silylating apparatus
Inventor: MIMURA YOSHIAKI
IPC: G03F7/36
Filed: 1987-08-24
Abstract: PURPOSE:To obtain a precise pattern by hardening a resist film by bringing a substrate into contact with an org. silane after exposure and development of the resist, then removing unnecessary reflection preventing film remaining on the substrate by decomposing the film with gaseous O2 plasma thereafter. CONSTITUTION:A substrate having a photosensitive film thereon is formed by coating the substrate with a reflection preventing film and a resist film. A resist pattern is formed by exposing the substrate and carrying out resist development. Then, in a stage 1, the substrate is heated and brought into contact with a soln. or vapor of an organosilane (dimethyl chlorosilane, etc.). In this stage, the resist film is hardened by a silylating reaction by irradiating the film with far-ultraviolet rays. By this treatment, resistance to O2 plasma is imparted to the resist film of a pattern. Then, in the second stage 2, the substrate is exposed to O2 plasma to remove the reflection preventing film remaining on the substrate other than the resist pattern by decomposing the film with O2 plasma. Since resistance to O2 plasma is imparted to the resist film by the silylating reaction, a fine pattern having high precision is obtd.
