Abstract:
1. An exposing method for directly exposing an exposure pattern on a photosensitive resin layer having sensitivity to an ultraviolet radiation formed on a substrate, comprising: modulating a radiant flux emitted from a first light source for emitting light consisting of a wavelength component in the wavelength range of 400 to 410 nm using a digital micro mirror device based on data of a desired exposure pattern; irradiating a resulting modulated radiant flux on said photosensitive resin layer so as to enable exposure of said photosensitive resin layer and to create said desired exposure pattern; and irradiating a second radiant flux emitted from a second light source for emitting light containing a wavelength component in the wavelength range of 450 to 2,500 nm on said photosensitive resin layer substantially simultaneously with said irradiating of said resulting modulated radiant flux on said photosensitive resin layer so as to enable exposure of said photosensitive resin layer and augment a photosensitive reaction in said photosensitive resin layer.
