  • Publication number: 20230161240
    Abstract: In a method of manufacturing a reflective mask, an adhesion layer is formed over a mask blank. The mask blank includes a substrate, a reflective multilayer disposed over the substrate, a capping layer disposed over the reflective multilayer, an absorber layer disposed over the capping layer, and a hard mask layer disposed over the absorber layer. A photoresist pattern is formed over the adhesion layer, the adhesion layer is patterned, the hard mask layer is patterned, and the absorber layer is patterned using the patterned hard mask layer as an etching mask. The photoresist layer has a higher adhesiveness to the adhesion layer than to the hard mask layer.
