摘要:
A method for repairing phase defects for an extreme ultraviolet (EUV) mask is disclosed. The method includes receiving a patterned EUV mask with at least one phase-defect region, determining location and size of the phase-defect region, depositing an absorber material to cover the phase-defect region and removing a portion of the patterned absorption layer near the phase-defect region in the patterned EUV mask to form an absorber-absent region.
