description | A method for producing a reflective optical component for an EUV projection exposure apparatus, the component having a substrate having a base body, and a reflective layer arranged on the substrate, wherein the substrate has an optically operative microstructuring, comprises the following steps: working the microstructuring into the substrate, polishing the substrate after the microstructuring has been worked into the substrate, applying the reflective layer to the substrate. A reflective optical component for an EUV projection exposure apparatus correspondingly has a polished surface between the microstructuring and the reflective layer. |
