Mold and method for manufacturing the same

摘要

The present invention discloses a mold and a method for manufacturing the mold. The mold includes a mold matrix having a molding surface, and a protective layer formed on the molding surface. The protective layer is made of a material chosen from the group consisting of iridium-rhenium alloy with a chromium nitride added therein and iridium-ruthenium alloy with a chromium nitride added therein. The method mainly includes the steps of: providing a mold matrix having a molding surface in a vacuum sputtering chamber, the vacuum sputtering chamber comprising a first target, the first target being comprised of a material chosen from the group consisting of iridium-rhenium alloy with a chromium nitride added therein and iridium-ruthenium alloy with a chromium nitride added therein; and forming a protective layer on the molding surface of the mold matrix by sputtering a target.
