Patent ID: 6849696

Claim:
A low dielectric constant material, comprising: a first backbone having a first aromatic moiety and a first reactive group; a second backbone having a second aromatic moiety and a second reactive group wherein the first and second backbones are crosslinked via the first and second reactive groups in a crosslinking reaction, wherein the reaction is a cycloaddition; and wherein at least one of the first or second backbones comprises at least one thermosetting monomer having the formula: wherein G is a cage structure, and wherein R 1 -R 4 comprises an alkyl group, an aryl group, a halogen atom, CF 3 , COOH, or NO 2 , wherein at least two of R 1 -R 4 comprises an aromatic portion and a reactive group, and wherein the reactive group on the at least one thermosetting monomer may comprise the first reactive group or the second reactive group.
