Abstract:
1. A method for manufacturing a microstructure comprising the following steps of: forming on a base plate a first photosensitive material layer to be exposed to light of a first wavelength region; forming on said first photosensitive material layer a second photosensitive material layer to be exposed to light of a second wavelength region; irradiating light of said second wavelength region to the surface of the base plate having the first and second photosensitive material layers formed thereon through a mask to enable only a desired area of said second photosensitive material layer to react; and irradiating light of said first wavelength region to the surface of the base plate having the first and second photosensitive material layers formed thereon through a mask to enable only a desired area of said first photosensitive material layer to react, wherein the upper and lower patterns are made different with respect to the base plate by use of each of said steps, and said first and second photosensitive material layers are positive type photosensitive materials, and lights of said first and second wavelength regions are ionizing radiations.
