发明名称 EUV magnetic contrast lithography mask and manufacture thereof
摘要 An EUV Lithography mask, a fabrication method, and use method thereof is provided. A preferred embodiment comprises a substrate, a Bragg reflector disposed upon the substrate, a buffer disposed upon the Bragg reflector, and an absorber layer disposed upon the buffer. The materials in the mask have selected magnetic properties. In a preferred embodiment, the buffer is a hard magnetic material, and the absorber is a soft magnetic material. Another preferred embodiment includes a mask manufacturing method further including a mask step. In a preferred embodiment, an electron mirror microscope is used to inspect the mask by imaging its topography with respect to its magnetic properties in an applied magnetic field.
