Abstract:
1. A method for fabricating a device, comprising the steps of: forming on a substrate a photosensitive layer not larger than 100 nm in thickness, wherein the photosensitive photoresist layer comprising an alkali soluble novolak resin and photosensitive compound having a naphthoquinone diazide group, and absorption coefficient α μm exposing the photosensitive photoresist layer to near-field light through a photomask having a light-shielding film and microapertures in the light-shielding film using the exposure light having a wavelength of 325 to 500 nm; forming a pattern based on the microapertures by developing the photosensitive photoresist layer; and etching a surface of the substrate based on the pattern.
