摘要： A photomask blank for producing a photomask to which an ArF excimer laser light is applied. The blank includes a light transmissive substrate on which a thin film having a multilayer structure is provided. The thin film has a light-shielding film in which a back-surface antireflection layer, a light-shielding layer and a front-surface antireflection layer are laminated in this order. The light-shielding layer comprises chromium and nitrogen, and the chromium content is more than 50 atomic %. The front-surface antireflection layer and the back-surface antireflection layer each has an amorphous structure made of a material comprising chromium, nitrogen, oxygen and carbon. The chromium content ratio of the front-surface antireflection layer and the back-surface antireflection layer is 40 atomic % or less. A first sum of nitrogen content and oxygen content of the back-surface antireflection layer is less than a second sum of nitrogen content and oxygen content of the front-surface antireflection layer.

摘要： A photomask blank is for use in manufacturing a photomask to be applied with exposure light having a wavelength of 200 nm or less. The photomask blank has a light-transmitting substrate and a light-shielding film formed thereon. The light-shielding film has a light-shielding layer containing a transition metal and silicon and a front-surface antireflection layer formed contiguously on the light-shielding layer and made of a material containing at least one of oxygen and nitrogen. The light-shielding film has a front-surface reflectance of a predetermined value or less for the exposure light and has a property capable of controlling the change width of the front-surface reflectance at the exposure wavelength to be within 2% when the thickness of the front-surface antireflection layer changes in the range of 2 nm. The material of the front-surface antireflection layer having a refractive index n and an extinction coefficient k capable of achieving such property is selected.
