Abstract:
1. A dielectric film comprising a dielectric material comprising atoms of Si, C, O and H, said dielectric material having a covalently bonded tri-dimensional network structure, a dielectric constant of not more than 2.7, a crack velocity in water on the order of less than 10 −10 meters per second, and a controlled porosity having molecular scale voids of between about 0.5 to about 20 nanometers in diameter, said molecular scale voids occupy a volume of between about 5% and about 60%, wherein said dielectric material has a substantially constant atom distribution throughout the film in both a vertical and horizontal direction and a substantially constant arrangement of atoms within the film in both the vertical and horizontal direction, and is derived from a single organosilane precursor with a built-in porogen and an oxidizing agent.
