<p>Fabrication of reflective masks, designed for use with x-ray delineating radiation in the construction of sub-micron devices, is expedited by use of a barrier layer intermediate the multilayer reflector and the absorber layer. The barrier is designed to reduce damage to the multilayer reflector during two stages of fabrication during initial patterning and during subtractive or additive mask repair. Composition of the barrier is so chosen as to minimize such damage during its removal in baring of the reflector, and also as to have requisite stability in regions retained during mask life.</p> |
