摘要： As shown in FIG. 1A, a first resist film 2 comprising organic high molecules and a second resist film 3 comprising a photosensitive material are sequentially applied to a substrate 1 by the spin coat method or the spray method for forming a two-layer resist. Then, a mask 4 with which a metallic fine opening pattern 6 is formed on a mask substrate 5 comprising a dielectric, such as glass, is tightly contacted with the two-layer resist. Then, light is projected onto the back of the mask substrate to carry out exposure with near field light 7 which is effused from the opening portions of the mask 4 where no metal is formed. Then, a pattern is formed by processing the second resist layer 3 for development with a developing solution. Thereafter, with the pattern in the second resist layer 3 being used as a mask, the first resist layer 2 is dry-etched with O2 plasma to form a fine pattern having a high aspect ratio, and with the pattern in the two-layer resist, the substrate is worked by etching, vapor deposition, or the like, before the two-layer resist is peeled off.
