Claims10
An insulating film forming composition, comprising:
- (A) at least one organic polymer, wherein the at least one organic polymer is a polymer of a monomer having at least one repeating unit containing a cage structure;
- (B) a solvent;
- and
- (C) at least one organic silicone compound represented by any of the following formulas (C-1) to (C-3):
- wherein,
- in formula (C-1), R1 represents a methyl group or phenyl group;
- and x1 is from 0 to 95 mol % and x2 is from 5 to 100 mol %, with the proviso that x1+x2=100 mol %;
- in formula (C-2), R2 and R3 each represents an alkyl group, with the proviso that at least one of R2 and R3 represents an alkyl group having 2 or more carbon atoms;
- R4 represents a methyl group or a 2-phenylpropyl group;
- and x3 is from 5 to 100 mol % and x4 is from 0 to 95 mol %, with the proviso that x3+x4=100 mol %;
- and
- in formula (C-3), Rf represents a fluoroalkyl group;
- and x5 is from 0 to 95 mol % and x6 is from 5 to 100 mol %, with the proviso that x5+x6=100 mol %.
