    摘要: A half-tone stacked film is designed so as to have a stacked structure of a first half-tone film and a second half-tone film, and the film thickness d, the refractive index n to exposure light and the extinction coefficient k of these half-tone films are designed so that one of these half-tone films becomes a phase advancement film and the other becomes a phase retardation film. When the film thickness (nm), the refractive index, and the extinction coefficient of the phase advancement film are represented by d(+), n(+) and k(+), respectively; and the film thickness (nm), the refractive index, and the extinction coefficient of the phase retardation film are d(−), n(−), and k(−), respectively; the phase advancement film has the relationship of k(+)>a1·n(+)+b1, and the phase retardation film has the relationship of k(−)

    摘要: A light-shieldable film is formed on one principal plane of an optically transparent substrate, and the light-shieldable film has a first light-shieldable film and a second light-shieldable film overlying the first light-shieldable film. The first light-shieldable film is a film that is not substantially etched by fluorine-based (F-based) dry etching and is primarily composed of chromium oxide, chromium nitride, chromium oxynitride or the like. The second light-shieldable film is a film that is primarily composed of a silicon-containing compound that can be etched by F-based dry etching, such as silicon oxide, silicon nitride, silicon oxynitride, silicon/transition-metal oxide, silicon/transition-metal nitride or silicon/transition-metal oxynitride.

    摘要: On a substrate that is transparent to exposure light, a phase-shift multilayer film including a stack of two layers of a metal silicide compound is formed. A stabilized oxide layer is formed on the surface of the metal silicide compound layer close to the top surface. The layer close to the substrate (the lower layer) of the phase-shift multilayer film is made of a relatively-metal-rich metal silicide compound, and the upper layer is made of a relatively-metal-poor metal silicide compound. The stabilized oxide layer has a metal-poor composition, and the metal content thereof is equal to or less than one third of the metal content of the lower layer. Thus, the stabilized oxide layer is highly chemically stable and has a high chemical resistance.

    摘要: In a halftone phase shift mask blank comprising a halftone phase shift film on a substrate which is transparent to exposure light, the halftone phase shift film comprises a metal, silicon, and optionally oxygen and nitrogen. The halftone phase shift film experiences a phase difference change of up to 1 deg. and a transmittance change of up to 0.2% before and after it is exposed to light in a cumulative dose of 1 kJ/cm2. The halftone phase shift film has excellent resistance to exposure light, specifically high-energy exposure light of short wavelength such as ArF or F2 laser beam (193 or 157 nm).

    摘要: A photomask blank has a light-shielding film composed of a single layer of a material containing a transition metal, silicon and nitrogen or a plurality of layers that include at least one layer made of a material containing a transition metal, silicon and nitrogen, and has one or more chrome-based material film. The high transition metal content ensures electrical conductivity, preventing charge-up in the photomask production process, and also provides sufficient chemical stability to cleaning in photomask production. The light-shielding film has a good resistance to dry etching of the chrome-based material film in the presence of chlorine and oxygen, thus ensuring a high processing accuracy.
