Patterning of nano-scale arrays by table-top extreme ultraviolet laser interferometric lithography
MetadataShow full item record
Arrays of nanodots were directly patterned by interferometric lithography using a bright table-top 46.9 nm laser. Multiple exposures with a Lloyd's mirror interferometer allowed to print arrays of 60 nm FWHM features. This laser-based extreme ultraviolet interferometric technique makes possible to print different nanoscale patterns using a compact tabletop set up.
