  • Patent number: 8852494
    Abstract: A method and apparatus for performing nanoimprint lithography. When an electric field is applied between the mold and the substrate, various forces can be generated among molds, substrates, and resists. The electrostatic force between the mold and the substrate can serve as an imprinting pressure to press the structured mold into the conformable resist. In addition, the electric field induces additional wetting forces (electrowetting or dielectrophoresis) in a liquid resist, which can assist the flow and filling of the liquid resist into fine structures.

  • Patent number: 8771562
    Abstract: An optical waveguide production method, employs a light-transmissive mold having higher dimensional accuracy for formation of an over-cladding layer. The mold for the formation of the over-cladding layer is unitarily produced by molding a light-transmissive resin with the use of a mold component having the same shape as the over-cladding layer. A recess formed in the mold by removing the mold component in the production of the mold serves as a cavity for the formation of the over-cladding layer. For the formation of the over-cladding layer, a photosensitive resin for the over-cladding layer is injected into the cavity of the mold, and exposed through the mold to be cured while a core formed in a predetermined pattern on a surface of an under-cladding layer is immersed in the photosensitive resin.
