Abstract: A ring-shaped glass spacer is to be arranged in contact with a magnetic disk in a hard disk drive device. A film that contains at least one of tin oxide, zinc oxide, and titanium oxide is formed on each surface of a main surface, and an outer circumferential edge surface, and an inner circumferential edge surface of the glass spacer. The thickness of the film on a center portion of the outer circumferential edge surface of the glass spacer is larger than the thickness of the film on a center portion of the inner circumferential edge surface of the glass spacer.

Abstract: A mask blank 100 has a structure in which a pattern-forming thin film 3 and a hard mask film 4 are formed on a transparent substrate 1 in this order. An Si2p narrow spectrum obtained by analyzing the hard mask film by X-ray photoelectron spectroscopy has a maximum peak at a binding energy of at least 103 eV. An N1s narrow spectrum obtained by analyzing the hard mask film by X-ray photoelectron spectroscopy has a maximum peak below a detection lower limit value. In the hard mask film 4, a content ratio (atomic %) of silicon and oxygen is Si:O=1:less than 2.

Abstract: Provided is a mask blank comprising a phase shift film A mask blank comprises a phase shift film on a transparent substrate. The phase shift film is made of a material comprising a transition metal, silicon, and nitrogen. A ratio of the total content of nitrogen and oxygen to the content of the transition metal is 12 or more and 19 or less in an internal region, wherein the internal region excludes a neighboring region of the phase shift film at an interface with the transparent substrate and a surface layer region of the phase shift film which is located opposite the transparent substrate.
