Abstract
Oligomers and polymers, useful as interlayer dielectric films, are formed by the co(hydrolysis/condensation) of an aryl group-containing trifunctional silanetriol or derivative with a tetrafunctional silicic acid compound. The respective tri- and tetrafunctional substituents on either silicon compound reaction are chosen so that they act as reactants in condensation oligomerization or polymerization reactions with the substituents on the other reactant.
