Publication number: 20250085622Abstract: EUV masks and methods of fabrication thereof are described herein. An exemplary method includes receiving an EUV mask having a multilayer structure, a capping layer disposed over the multilayer structure, a patterned absorber layer disposed over the capping layer, and a patterned hard mask disposed over the patterned absorber layer. The method further includes removing the patterned hard mask by performing a first etching process to partially remove the patterned hard mask and performing a second etching process to remove a remainder of the patterned hard mask.
