MASK BLANK SUBSTRATE, SUBSTRATE WITH MULTILAYER REFLECTION FILM, TRANSMISSIVE MASK BLANK, REFLECTIVE MASK, AND SEMICONDUCTOR DEVICE FABRICATION METHOD

Disclosed is a mask blank substrate for use in lithography, wherein the main surface on which the transfer pattern of the substrate is formed has a root mean square roughness (Rms) of not more than 0.15 nm obtained by measuring an area of 1 μm×1 μm with an atomic force microscope, and has a power sp...

Zusammenfassung:	Disclosed is a mask blank substrate for use in lithography, wherein the main surface on which the transfer pattern of the substrate is formed has a root mean square roughness (Rms) of not more than 0.15 nm obtained by measuring an area of 1 μm×1 μm with an atomic force microscope, and has a power spectrum density of not more than 10 nm4 at a spatial frequency of not less than 1 μm−1.
