Patent ID: 8383737

Claim:
A composition for filling small gaps in a semiconductor device which comprises: a polycondensate represented by Formula 4: {(R′SiO 1.5 ) x (HSiO 1.5 ) y (X(CH 2 ) n SiO 1.5 ) z } m (4), wherein x, y and z satisfy the relations x+y+z=1, 0.05≦x≦0.9, 0≦y≦0.9 and 0.05≦z≦0.9, X is a C 6 -C 12 aryl group, R′ is a C 1 -C 6 alkyl group, n is from 0 to 2, and m is from 12 to 2,000; a solvent; at least one stabilizer selected from organic and inorganic anhydrides; a crosslinking component; and a crosslinking acid catalyst selected from mineral acids, sulfonic acid, oxalic acid, maleic acid, hexamic acid, cyclohexylsulfonic acid, phthalic acid, and mixtures thereof; wherein the crosslinking component is present in an amount of 0.1 to 30 parts by weight, based on 100 parts by weight of the polycondensate.
