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.
