Abstract:
On an etching target film formed on a substrate, a three-layer resist is laminated. This three-layer resist includes an organic film and a resist film developed into a resist pattern. Through the resist pattern, the organic film is etched into a mask pattern through which the etching target film will be etched.The organic film is etched with plasma which is obtained by exciting a process gas containing carbon dioxide and hydrogen to the plasma state. This scheme makes it possible to form a high perpendicularity mask pattern in the organic film.
