  • Publication number: 20250164877
    Abstract: A radiation-sensitive composition contains a polymer having an acid-releasable group, and a compound represented by formula (1). In the formula (1), L1 represents a group having a (thio)acetal ring or the like. W1 represents a single bond or a (b+1)-valent organic group having 1 to 40 carbon atoms. R1, R2, and R3 each independently represent a hydrogen atom, a hydrocarbon group having 1 to 10 carbon atoms, a fluorine atom, or a fluoroalkyl group. Rf represents a fluorine atom or a fluoroalkyl group. a represents an integer of 0 to 8. b represents an integer of 1 to 4. d represents 1 or 2. When a represents 2 or more, a plurality of R1 are the same or different, and a plurality of R2 are the same or different. M+ represents a monovalent cation.

  • Publication number: 20110223544
    Abstract: A resist pattern coating agent includes a hydroxyl group-containing resin and a solvent. The solvent includes an alcohol shown by a following formula (1) in an amount of about 30 mass % or more, R—OH??(1) wherein R represents a branched alkyl group having 3 to 10 carbon atoms. The resist pattern coating agent is used in a resist pattern-forming method. The method includes forming a first resist pattern on a substrate using a first radiation-sensitive resin composition. The first resist pattern is treated with the resist pattern coating agent. A second resist pattern is formed on the substrate treated with the resist pattern coating agent using a second radiation-sensitive resin composition.

  • Publication number: 20040231777
    Abstract: A method of processing an organosiloxane film includes loading, into a reaction container (1), a substrate (W) with a coating film of a polysiloxane base solution applied thereon. The solution contains bond of a silicon atom with a functional group selected from the group consisting of a methyl group, phenyl group, and vinyl group. The method also includes subjecting the substrate (W) to a heat process in the reaction container (1) to bake the coating film. The heat process is performed in a process atmosphere that includes a catalytic agent gas containing a mixture of ammonia and water, at a process temperature of from 300 to 400° C.
