Abstract

PURPOSE:To obtain a fine pattern by forming a thin metallic film on a lower thin resist and an upper thick resist on the metallic film, etching the metallic film with the upper resist as a mask, and further etching the metallic film with the lower resist as a mask. CONSTITUTION:A thin metallic film 2 is formed on a glass substrate 1, a thin lower resist layer 6 is coated on the film, is patterned, and the processed part 4 is exposed. Then, a thin metallic film 7 is coated on the lower resist layer 6 including the exposed part, an upper resist layer 8 is coated thereon, and is patterned. With the upper resist layer 8 thus patterned as a mask the intermediate metallic film 7 is dry etched and removed, and the metallic film 2 is positively removed with high accuracy by dry etching with the layer 8, the film 7 and the layer 6 as masks.
