COMPOSITION FOR POROUS FILM FORMATION, POROUS FILM, PROCESS FOR PRODUCING THE SAME, INTERLAYER INSULATION FILM AND SEMICONDUCTOR DEVICE |
摘要 |
<p>A composition for film formation from which a porous film excelling in dielectric characteristics, adherence, coating film uniformity and mechanical strength and realizing reduced moisture absorption can be prepared; a porous film and a process for producing the same; and a highly reliable semiconductor device of high performance wherein the porous film is incorporated. In particular, a composition for film formation, obtained by performing hydrolytic condensation under acid or alkali conditions of a mixture of 100 parts by weight of at least one compound selected from the group consisting of hydrolyzable silicon compounds of the following general formulae R<1>aSiZ<1>4-a (1) and R<2>b(Z<2>)3-bSi-Y-Si(R<3>)cZ<3>3-c (2) and products of hydrolytic condensation of portion thereof and 0.1 to 20 parts by weight of at least one crosslinking agent selected from the group consisting of cyclic or multi-branched oligomers of limited structures represented by the following general formulae (3) to (8): ÄR<4>(H)SiOÜeÄR<5>(Z<4>)SiOÜf (3); (R<6>SiO3/2)gÄR<7>(H)SiOÜhÄR<8>(Z<5>)SiOÜi (HSiO3/2)j(Z<6>SiO3/2)k ÄH(Me)2SiO1/2ÜLÄZ<7>(Me)2SiO1/2Üm(R<9>SiO3/2)nÄR<10>(Z<8>)SiOÜo ÄH(Me)2SiO1/2ÜpÄZ<9>(Me)2SiO1/2Üq(SiO2)r(Z<10>SiO3/2)s (Z<11>3SiO1/2)t(R<11>2SiO)u(R<12>SiO3/2)vÄR<13>(Z<12>)SiOÜw(SiO2)x(Z<13>SiO3/2)y</p> |
