    摘要: There is disclosed a coated-type silicon-containing film stripping process for stripping off to remove a coated-type silicon-containing film obtained by coating a silicon-containing film composition used in a lithography on a substrate, comprising, at least: a first step of treating the silicon-containing film with an acidic stripping solution containing sulphate ion and/or fluoride ion; and a second step of treating the silicon-containing film with an alkaline stripping solution containing a nitrogen compound. There can be provided a process for allowing a silicon-containing film, which has not been conventionally removed unless dry stripping is adopted, to be removed by a stripping process based on a stripping solution (wet stripping).

    摘要: A photomask blank is provided comprising a transparent substrate, a single or multi-layer film including an outermost layer composed of chromium base material, and an etching mask film. The etching mask film is a silicon oxide base material film formed of a composition comprising a hydrolytic condensate of a hydrolyzable silane, a crosslink promoter, and an organic solvent and having a thickness of 1-10 nm. The etching mask film has high resistance to chlorine dry etching, ensuring high-accuracy processing of the photomask blank.
