  • Publication number: 20130115434
    Abstract: A manufacturing method of a photonic crystal is provided. In the method, a high-refractive-index material is conformally deposited on an exposed portion of a periodic template composed of a low-refractive-index material by an atomic layer deposition process so that a difference in refractive indices or dielectric constants between the template and adjacent air becomes greater, which makes it possible to form a three-dimensional photonic crystal having a superior photonic bandgap. Herein, the three-dimensional structure may be prepared by a layer-by-layer method.

  • Patent number: 7507505
    Abstract: The present invention relates to a method for manufacturing a reflective multi-layered thin film mirror for an extreme ultraviolet radiation (EUV) exposure process that is one of the next generation exposure process masks using an atomic force microscope (AFM). This reflective multi-layered thin film mirror for extreme ultraviolet radiation (EUV) exposure process allows metal oxide structures with fixed height and ' width to be obtained using anodic oxidization phenomenon between the cantilever tip of a atomic force microscope and an absorber material during the patterning of an absorber layer on a multi-layered thin film of a substrate, followed by forming the ultra-fine line width absorber patterns via etching of the metal oxide structure.
