摘要： A method of manufacturing a stamper/imprinter for use in patterning of a recording medium comprising the sequential steps of providing a substrate/workpiece comprising a topographical pattern formed in a portion of a surface of the substrate/workpiece. The pattern defines a periphery. An alignment mark is formed in another portion of the surface of surrounding the periphery. An opaque protective film is formed overlying the entirety of the surface. A peripheral portion of the protective film is removed to expose the alignment mark. Selected portions of the substrate/workpiece are removed while the alignment mark is utilized for accurate alignment during the removal process. Remaining portions of the protective film are removed prior to use.
