摘要:
A cleaning composition and process for cleaning post-chemical mechanical polishing (CMP) residue and contaminants from a microelectronic device having said residue and contaminants thereon. The cleaning compositions include novel corrosion inhibitors. The composition achieves highly efficacious cleaning of the post-CMP residue and contaminant material from the surface of the microelectronic device without compromising the low-k dielectric material or the copper interconnect material.

摘要:
Chemical mechanical polishing (CMP) compositions and single CMP platen process for the removal of copper and barrier layer material from a microelectronic device substrate having same thereon. The process includes the in situ transformation of a copper removal CMP composition, which is used to selectively remove and planarize copper, into a barrier removal CMP composition, which is used to selectively remove barrier layer material, on a single CMP platen pad.

摘要:
A cleaning composition and process for cleaning post-chemical mechanical polishing (CMP) residue and contaminants from a microelectronic device having said residue and contaminants thereon. The cleaning compositions include at least one quaternary base, at least one amine, at least one corrosion inhibitor, and at least one solvent. The composition achieves highly efficacious cleaning of the post-CMP residue and contaminant material from the surface of the microelectronic device while being compatible with barrier layers.
摘要:
A method of passivating a CMP composition by dilution and determining the relationship between the extent of dilution and the static etch rate of copper. Such relationship may be used to control the CMP composition during the CMP polish to minimize the occurrence of dishing or other adverse planarization deficiencies in the polished copper, even in the presence of substantial levels of copper ions in the CMP composition and at the copper/CMP composition interface.
摘要:
A CMP composition containing 5-aminotetrazole, e.g., in combination with oxidizing agent, chelating agent, abrasive and solvent and a method of use. Such CMP composition may be diluted during the CMP polish to minimize the occurrence of dishing or other adverse planarization deficiencies in the polished copper, even in the presence of substantial levels of copper ions in the CMP composition and at the copper/CMP composition interface during CMP processing.

Chemical mechanical polishing (CMP) compositions and single CMP platen process for the removal of copper and barrier layer material from a microelectronic device substrate having same thereon. The process includes the in situ transformation of a Step I slurry formulation, which is used to selectively remove and planarize copper, into a Step II slurry formulation, which is used to selectively remove barrier layer material, on a single CMP platen pad.
