    摘要: A chemical mechanical polishing process including a single copper removal CMP slurry formulation for planarization of a microelectronic device structure preferably having copper deposited thereon. The process includes the bulk removal of a copper layer using a first CMP slurry formulation having oxidizing agent, passivating agent, abrasive and solvent, and the soft polishing and over-polishing of the microelectronic device structure using a formulation including the first CMP slurry formulation and at least one additional additive. The CMP process described herein provides a high copper removal rate, a comparatively low barrier material removal rate, appropriate material selectivity ranges to minimize copper dishing at the onset of barrier material exposure, and good planarization efficiency.

    摘要: A method for repairing defects in a surface layer of a substrate. The method comprises the redeposition, in a solvent environment, of a fill material into the defects of the surface layer. The fill material is provided by the surface layer itself or from a separate source comprising a different material from that of the surface layer.
