Patent ID: 7235500

Claim:
A material for forming a silica based film comprising a solid fraction containing a film forming component capable of generating a silica based film, an organic solvent, and water, wherein the water content of said material, as determined by gas chromatography measurement, is within a range from 0.1 to 50% by weight, and wherein said film forming component comprises a reaction product generated by subjecting a silicon compound selected from the group consisting of a compound represented by general formula I shown below and a compound represented by general formula II shown below, to hydrolysis: R 1 2 Si(OR 2 ) 2 (I), wherein R 1 is an alkyl group having 1–4 carbon atoms or a phenyl group, and R 2 is an alkyl group having 1–4 carbon atoms; and R 3 Si(OR 4 ) 3 (II), wherein R 3 is an alkyl group having 1–4 carbon atoms or a phenyl group, and R 4 is an alkyl group having 1–4 carbon atoms (II).
