  • Publication number: 20250044697
    Abstract: A method for producing a semiconductor device includes applying a composition for forming a silicon-containing resist underlayer film, wherein the composition comprises a polysiloxane having a unit structure including a carbonyl group-containing functional group, wherein the silicon-containing resist underlayer film is used as a mask layer in a step of removing the mask layer with hydrogen peroxide-containing chemical after transfer of a pattern to an underlayer by lithography process onto a semiconductor substrate, followed by baking the composition, to thereby form a resist underlayer film, applying a resist composition onto resist underlayer film to thereby form a resist film, exposing the resist film to light, developing the resist after the light exposure to thereby form a resist pattern, etching the resist underlayer film with the resist pattern, processing the semiconductor substrate with the patterned resist and resist underlayer film, and removing the mask layer with a hydrogen peroxide-containing ch
