THIN FILM MATERIALS FOR THE PREPARATION OF ATTENUATING PHASE SHIFT MASKS

The fabrication of transmissive attenuating types of phase shift masks by formation of and selective etch of a layer, deposited on a substrate. This single layer provides both the phase shift and the attenuation required and is readily patterned and processed to produce attenuating phase shift masks...
