Abstract:
1. A method for fabricating a color filter using a surface plasmon, the method comprising: forming a metallic film formed of a conductive material on a substrate; forming, on the metallic film, a dielectric layer formed of a dielectric material having a refractive index equal to or similar to that of the substrate; forming a predetermined photosensitive pattern on the substrate having the dielectric layer formed thereon; forming, below the predetermined photosensitive pattern, a dielectric pattern formed of the dielectric material, by selectively removing the dielectric layer by using the photosensitive pattern as a mask; forming, in a metal layer formed of the metallic film, a transmissive pattern consisting of a plurality of sub-wavelength holes having a period, by selectively removing the metal layer by using the photosensitive pattern as a mask; and forming, on the metal layer including the transmissive pattern, an insulating layer formed of the same material as the dielectric material.
