    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: 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: Disclosed herein is a dry etching method for a work layer formed over a substrate, including the steps of forming a hard mask layer over the work layer formed over the substrate, forming a resist pattern over the hard mask layer, transferring the resist pattern to the hard mask layer by first dry etching conducted using the resist pattern, and patterning the work layer by second dry etching conducted using a hard mask pattern obtained upon the transfer to the hard mask layer, wherein after the hard mask layer is patterned by the first dry etching, the patterning of the work layer by the second dry etching is conducted through changing the concentration of an auxiliary ingredient of a dry etching gas, without changing a main ingredient of the dry etching gas, in an etching apparatus in which the first dry etching has been conducted.
