Abstract:
A three-phase composite material suitable for use as an interlayer dielectric, comprising:an organic matrix representing about 40 to 90 weight percent of said composite, wherein:said organic matrix is formed from a composition comprising an organic-component precursor present in an amount in the range of about 40 to 90 weight percent of said composition;said organic matrix has pores; andsaid pores are formed from a microporosity-imparting agent; andinorganic particles, at least some of which are coupled to said organic matrix, wherein:the coupling is promoted by a moiety present in said composition, which moiety links said inorganic particles to said organic-component precursor or a reaction product thereof;said inorganic particles contain a metal;said inorganic particles are characterized by an average particle size of less than one micron;said inorganic particles are present in an amount within a range of about 1 to about 50 weight percent of the composite material.
