Patent ID: 8614032

Claim:
A fabricating method of a laser reflective mask, the method comprising the steps of: forming a sacrificial layer on top of a base substrate; etching an opening through the sacrificial layer and recessing the base substrate by an etching process, for a region prearranged as a reflection region for a laser beam in the base substrate, to form a sacrificial layer pattern and a reflective layer filling groove having a predetermined depth; alternately and repeatedly laminating first and second reflective layers having different reflectances on top of the base substrate, the sacrificial layer pattern and the reflective layer filling groove formed on the base substrate, until the reflective layer filling groove is completely filled; removing the sacrificial layer pattern and the first and second reflective layers laminated on top of the sacrificial layer pattern by a laser lift-off process of irradiating the base substrate with the laser beam from a bottom surface of the base substrate, to form a reflective layer pattern configured in the reflective layer filling groove; and removing the sacrificial layer pattern remaining on top of the base substrate.
