Patent ID: 8188576

Claim:
A compound for filling small gaps in a semiconductor device, the compound comprising: hydrolysates prepared by hydrolysis, in the presence of an acid catalyst, of compounds represented by Formulae 1, 2, and 3: [RO] 3 Si—[CH 2 ] n R′ (1) wherein, in Formula 1, n is an integer from 0 to about 10, and R and R′ are each independently a hydrogen atom, a C1-C12 alkyl group, or a C6-C20 aryl group; HOOC[CH 2 ] n R 2 Si—O—SiR′ 2 [CH 2 ] n COOH (2) wherein, in Formula 2, each n is independently an integer from 0 to about 10, and R and R′ are each independently a C1-C12 alkyl group, or a C6-C20 aryl group; and R 3 Si—O—X (3) wherein, in Formula 3, X is R′ or SiR′ 3 , and R and R′ are each independently a C1-C12 alkyl group or a C6-C20 aryl group, or a polycondensate prepared by polycondensation of the hydrolysates represented by Formulae 1, 2, and 3.
