Abstract: Methods of manufacturing a nanoimprint stamp are provided. The method may include forming a pattern on a surface of a master substrate, depositing an etch barrier layer on a surface of a stamp substrate, coating a photoresist on one of the surfaces of the master substrate and the stamp substrate on which an etch barrier layer is formed, forming a photoresist pattern by pressing the master substrate against the stamp substrate, forming a hard mask by etching the etch barrier layer using the photoresist pattern, and etching the stamp substrate using the hard mask as an etch mask.

Abstract: A nanoimprint stamp having an alignment mark includes a transparent substrate having a plurality of convex portions, and a semitransparent layer on each of the plurality of convex portions. The semitransparent layer has a transmittance of about 20% to about 80% with respect to ultraviolet rays.
