    摘要: An oxidizing slurry for removal of low dielectric constant materials. The slurry is formed utilizing non-oxidizing particles with a separate oxidizing agent, oxidizing particles alone or reducible abrasive particles with a compatible oxidizing agent. The particles can be formed of a metal oxide, nitride, or carbide material, by itself or mixtures thereof, or can be coated on a core material such as silicon dioxide or can be coformed therewith. A preferred oxidizing slurry is multi-modal in particle size distribution. Although developed for utilization in CMP semiconductor processing the oxidizing slurry of the present invention also can be utilized for other high precision polishing processes.

    摘要: A method for implementing a bismaleimide (BMI) polymer as a sacrificial material for an integrated circuit air gap dielectric. The method of one embodiment comprises forming a first and second metal interconnect lines on a substrate, wherein at least a portion of the first and second metal interconnect lines extend parallel to one another and wherein a trough is located between the parallel portion of said first and second metal interconnect lines. A layer of bismaleimide is spin coated over the substrate. The layer of bismaleimide is polished with a chemical mechanical polish, wherein the trough remains filled with the bismaleimide. A diffusion layer is formed over the substrate. The substrate is heated to activate a pyrolysis of the bismaleimide. An air gap is formed in the trough in the space vacated by the bismaleimide.
