    摘要: Provided is a mask blank that is improved in adhesion of a thin film for forming a transfer pattern to a resist, thus capable of suppressing the occurrence of collapse, chipping, or the like of a formed resist pattern. The mask blank has, on a transparent substrate 1, a thin film 2 which is for forming a transfer pattern and is made of a material containing a metal. The thin film 2 has a surface modified layer in the form of an oxide film containing a hydrocarbon. The surface modified layer of the thin film 2 can be formed by, for example, causing a highly concentrated ozone gas and an unsaturated hydrocarbon gas to act on the thin film.

    摘要: A relative density of a light-shielding film made of MoSi, which is given by relative density=(actual density/theoretical density)×100, is obtained using a density (actual density) calculated by an XRR method and a theoretical density obtained from a material composition. By obtaining a dense film having a relative density greater than 94%, the thickness of an alterated layer, caused by exposure light, at a surface of the MoSi film can be made not more than 2.0 nm so that the dimensional change of a transfer pattern can be made small.

    摘要: The present invention is a method of manufacturing a transfer mask with use of a mask blank in which a thin film for pattern formation and a chromium-based thin film made of a material containing chromium are stacked on a transparent substrate in this order. The thin film for pattern formation is made of material containing silicon and a transition metal other than chromium. The chromium-based thin film is made of a material containing chromium. Exposure light having a wavelength of 200 nm or less is applied to the transfer mask. In the manufacturing method, the transfer mask is produced by performing, in the following order, a process of forming a resist film having a transfer pattern on the chromium-based thin film, a process of forming a transfer pattern in the chromium-based thin film with use of a mask of the resist film having the transfer pattern, a process of forming a transfer pattern in the thin film for pattern formation with use of a mask of the chromium-based thin film having the transfer pattern, and a process of removing the chromium-based thin film by etching. The manufacturing method further includes a cleaning process of at least one of alkali solution cleaning, hot water cleaning, and ozone-containing water cleaning on the produced transfer mask until a width of the transfer pattern of the thin film for pattern formation is reduced by 4 nm or a space width of the thin film for pattern formation is increased by 4 nm.

    摘要: Disclosed are the novel C-glycoside compounds Mer-1020dA, Mer-1020dB, Mer-1020dC and Mer-1020dD which have a chromophore group in common with well-known chrysomycins A and B, but can be distinguished from the chrysomycins and the like in that the novel C-glycoside compounds have a sugar residue having a higher degree of oxidation, as well as the compound Mer-1020dE comprising only the chromophore thereof. Among these compounds, the C-glycoside compounds are antibiotics which have low toxicity and can strongly inhibit the growth of solid cancer cells in particular.
