    Abstract: Gas releasing compositions that can facilitate improved patterning of organometallic resists are described. The gas releasing compositions can release water, carbon dioxide, or alcohols in response to radiation or heating. A film-forming composition is composed of a flowable blend of a reactive gas releasing moiety, a matrix forming species, an organic solvent, and an optional activating agent. An underlayer composition is composed of a blend of a reactive gas releasing moiety, a polymer matrix and an optional activating additive. Multilayer structures are described based on organometallic radiation sensitive patterning compositions, such as alkyl tin oxo-hydroxo compositions, which are placed over a gas releasing underlayer formed on a substrate, such as a semiconductor wafer. Methods for patterning multilayer structures are also described.

    Abstract: A composition includes: a solvent; and a compound including: at least one structural unit selected from the group consisting of a structural unit represented by formula (1-1) and a structural unit represented by formula (1-2); and a structural unit represented by formula (2-1). X is a monovalent organic group other than an alkoxy group, the monovalent organic group having 1 to 20 carbon atoms and having at least one fluorine atom; Y is a monovalent organic group having 1 to 20 carbon atoms, a hydroxy group, or a halogen atom; R0 is a substituted or unsubstituted divalent hydrocarbon group having 1 to 20 carbon atoms; R1 is a monovalent organic group having 1 to 20 carbon atoms and having no fluorine atom, a hydroxy group, a hydrogen atom, or a halogen atom; and R2 is a substituted or unsubstituted divalent hydrocarbon group having 1 to 20 carbon atoms.
