Abstract:
1. A substrate processing apparatus comprising: a processing chamber for processing a substrate; a material supply unit for supplying a silicon-containing material, an oxidation material and a catalyst into the processing chamber; a heating unit for heating the substrate; and a controller for controlling at least the material supply unit and the heating unit, wherein the is configured to control the heating unit to heat the substrate with a first photoresist pattern formed thereon at processing temperature lower than a deformation temperature of a first photoresist constituting the first photoresist pattern, and to control the material supply unit to alternately supply the silicon-containing material and the catalyst, and to alternately supply the oxidation material and the catalyst into the processing chamber in a repeated manner to form on the substrate a thin film having a thickness equal to 5% of one half pitch of the first photoresist pattern.
