Patent ID: 8603349

Claim:
A method of manufacturing a nanoimprint stamp, the method comprising: 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 surface of the master substrate and the surface of the stamp substrate; pressing the master substrate against the stamp substrate to compress the photoresist; forming a photoresist pattern on the stamp substrate by hardening the photoresist; forming a hard mask on the stamp substrate by etching the etch barrier layer using the photoresist pattern; and etching the stamp substrate using the hard mask as an etch mask, wherein the etch barrier layer includes one of a first metal including at least one of Cr, Ti, Ta, Pt, Au, and Mo and a metal oxide or a metal nitride that is formed by combining oxygen or nitrogen with the first metal, and the etch barrier layer is formed to have a thickness in a range from about 1 nm to about 20 nm.
