  • Publication number: 20180240668
    Abstract: A mask for semiconductor manufacturing includes a mask substrate, a shifter layer over the mask substrate, a stop layer over and in contact with the shifter layer, and an absorber layer over the stop layer. The shifter layer includes each material of a set of materials, the materials being combined in a first proportion in the shifter layer. The stop layer includes each material of the set of materials, the materials being combined in a second proportion in the stop layer that is different from the first proportion.

  • Patent number: 9953833
    Abstract: Provided is a method for creating a mask blank that includes a capping layer and a shifter layer. The capping layer is optically compatible and process compatible with the shifter layer. The method may include providing a cleaned and polished mask substrate to a deposition tool and depositing, within the deposition tool, a shifter layer over a cleaned and polished mask substrate. The shifter layer may include each material of a set of materials in a first proportion. The method may also include depositing an additional layer over the shifter layer, the additional layer providing a capping layer over the shifter layer. The capping layer includes the materials in a second proportion unequal to the first proportion. The capping layer includes molybdenum, silicon, and nitride in a proportion that aids in detection by a residual gas analyzer. Also provided is also a mask blank structure incorporating the compatible capping layer.

  • Publication number: 20170168387
    Abstract: A system and method for repairing a photolithographic mask is provided. An embodiment comprises forming a shielding layer over an absorbance layer on a substrate. Once the shielding layer is in place, the absorbance layer may be repaired using, e.g., an e-beam process to initiate a reaction to repair a defect in the absorbance layer, with the shielding layer being used to shield the remainder of the absorbance layer from undesirable etching during the repair process.

  • Patent number: 9142423
    Abstract: Provided is a method for creating a mask blank that includes 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 detection of included materials with a residual gas analyzer. Provided is also a mask blank structure which incorporates the compatible stop layer.
