摘要: Provided is a method for creating a mask blank that include a stop layer. The stop layer is optically compatible and process compatible with other layers included as part of the mask blanks. Such blanks may include EUV, phase-shifting, or OMOG masks. The stop layer includes molybdenum, silicon, and nitride in a proportion that allows for compatibility and aids in detection by a residual gas analyzer. Provided is also a method for the patterning of mask blanks with a stop layer, particularly the method for removing semi-transparent residue defects that may occur due to problems in prior mask creation steps. The method involves the detect of included materials with a residual gas analyzer. Provided is also a mask blank structure which incorporates the compatible stop layer.

摘要: A method for controlling phase angle of a mask is provided. A mask comprising a substrate and an absorber is formed. A nitrogen-containing plasma treatment is performed on the mask to reduce the phase angle. Alternatively, a nitrogen-containing plasma treatment is performed on the mask, followed by a vacuum ultraviolet treatment to form a passivated layer on the mask.
