  • Patent number: 9720330
    Abstract: Methods of micro- and nano-patterning substrates to form transparent conductive electrode structures or polarizers by continuous near-field optical nanolithography methods using a roll-type photomask or phase-shift mask are provided. In such methods, a near-field optical nanolithography technique uses a phase-shift or photo-mask roller that comprises a rigid patterned externally exposed surface that transfers a pattern to an underlying substrate. The roller device may have an internally disposed radiation source that generates radiation that passes through the rigid patterned surface to the substrate during the patterning process. Sub-wavelength resolution is achieved using near-field exposure of photoresist material through the cylindrical rigid phase-mask, allowing dynamic and high throughput continuous patterning.

  • Patent number: 9703197
    Abstract: A resist film structure is provided, which allows a resist layer to have improved photosensitivity to EUV or electron beams without changing the photosensitivity of the resist material itself. A metal layer 1 with a thickness as small as a nanometer level is provided on a resist polymer layer 2 formed on a substrate 3. When the resist layer in this structure is exposed to light, the metal layer 1 produces a surface plasmon effect to enhance the irradiation to the resist film, so that the photosensitivity of the resist film is improved.
