Patent ID: 8299197

Claim:
A composition for gap-filling in a semiconductor device, the composition comprising: a polymer as represented by Formula 5: {(R′SiO 1.5 ) s (HSiO 1.5 ) t (X(CH 2 ) p SiO 1.5 ) u (SiO 1.5 (CH 2 ) m SiO 1.5 ) v } n (5) wherein: s, t, u, and v satisfy the relations s+t+u+v=1, 0<u, and 0<v, provided that s and t are not simultaneously zero, X is a C 6 -C 12 aryl group, R′ is a C 1 -C 6 alkyl group, p and m are independently from 0 to 2, and n is 1 or more; an organic solvent, wherein the organic solvent is present in an amount of about 100 to about 3,000 parts by weight, based on 100 parts by weight of the polymer; and a crosslinker, wherein the crosslinker includes one or more of melamine-based crosslinkers, substituted urea-based crosslinkers, epoxy-containing polymers, and derivatives thereof.
