Lithography Mask and Method of Forming a Lithography Mask |
摘要 |
A first embodiment is a lithography mask comprising a transparent substrate and a first molybdenum silicon nitride (MoxSiyNz) layer. The first MoxSiyNz layer is over the transparent substrate. A percentage of molybdenum (x) of the first MoxSiyNz layer is between 1 and 2. A percentage of silicon (y) of the first MoxSiyNz layer is between 50 and 55. A percentage of nitride (z) of the first MoxSiyNz layer is between 40 and 50. The first MoxSiyNz layer has an opening therethrough. |

1. A method for forming a lithography mask, the method comprising:
forming a molybdenum-containing layer over a transparent substrate, the molybdenum-containing layer comprising a first portion with a first percentage of molybdenum substantially uniformly throughout a thickness of the first portion and a second portion with a second percentage of molybdenum substantially uniformly throughout a thickness of the second portion, the first percentage being different from the second percentage; and forming a first opening through the molybdenum-containing layer. |
