Patent ID: 8728331

Claim:
A method of fabricating an imprint mold comprising: forming a metal film on a substrate; forming first and second photo resist patterns on the metal film; etching the metal film and the substrate using the first and second photo resist patterns to form first and second metal patterns and a first pattern; removing the second photo resist pattern and the second metal pattern to form third metal pattern; and etching the substrate using the first photo resist pattern and third metal pattern as an etch mask to form a second pattern derived from the substrate and a third pattern derived from the first pattern, wherein the etching processes using the first and second photo resist patterns are performed in the wet etching method, and wherein the second metal pattern is formed to a narrower width than that of the first metal pattern, wherein the first and second metal pattern are simultaneously etched through the wet etching process, the second metal pattern is entirely removed and a part of the first metal pattern remains, the remained portion of the first metal pattern is used as a third metal pattern.
