    摘要: A phase shift mask blank comprising a transparent substrate and at least one layer of a phase shifter thereon, wherein the phase shifter is a film composed primarily of a fluorine-doped metal silicide, can be fabricated into a high-performance phase shift mask having adequate transmittance and good stability over time even when used with light sources that emit short-wavelength light. The phase shift mask can be used to fabricate semiconductor integrated circuits to a smaller minimum feature size and a higher level of integration.

    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 phase shift mask comprising an exposure light-transmitting substrate and a second light-transmitting region thereon, the second light-transmitting region functions as a phase shifter and is made of a fluorine-doped molybdenum silicide film or fluorine-doped chromium silicide film formed by a sputtering technique that uses molybdenum metal, chromium metal, molybdenum silicide or chromium silicide as the target and SiF2 as the reactive gas. The phase shifter has a high refractive index to short-wavelength exposure light, enabling a 180-degree phase change to be achieved at a minimum film thickness, and also has a good stability to such light. The phase shift mask can be used to fabricate semiconductor integrated circuits to a smaller minimum feature size and a higher level of integration.

    摘要: In a photomask blank comprising a light-shielding film and an antireflective film on a transparent substrate, the light-shielding film and the antireflective film are formed of a chromium base material containing oxygen, nitrogen and carbon such that the content of carbon decreases stepwise or continuously from a surface side toward the substrate. The photomask blank can be etched at a controlled rate to produce perpendicular walls. A photomask is manufactured by lithographically patterning the photomask blank. The photomask blank and photomask have uniform film properties and contribute to the microfabrication of semiconductor ICs of greater density and finer feature size.
