Abstract:
1. An insulating-film forming material comprising a polymer (A) that has, as a repeating unit thereof, a structure represented by the following general formula (I): wherein R 1 to R 7 are the same or different, and each represents a monovalent group; one of X, Y and Z represents a group represented by formula (IA), and another one of X, Y and Z is —O—, and the other one of X, Y and Z is a group represented by formula (IB) wherein the oxygen atom that directly bonds to the silicon atom in formula (IB) is also connected to formula (I); and n indicates an integer of from 1 to 10: wherein R 8 to R 10 are the same or different, and each represents a monovalent group, wherein R 11 to R 14 are the same or different, and each represents a monovalent group; R 15 to R 17 are the same or different, and each represents a single bond or a divalent group; R 18 represents a single bond or —O—; m indicates an integer of from 0 to 10; and at least one of R 1 to R 17 in formula (I) includes at least one carbon-carbon triple bond or is a monovalent group capable of becoming a hydrocarbon group through a Diels-Alder reaction followed by an elimination reaction.
