Abstract:
The present disclosure provides a concentrate for use in chemical mechanical polishing slurries, and a method of diluting that concentrate to a point of use slurry. The concentrate comprises abrasive, complexing agent, and corrosion inhibitor, and the concentrate is diluted with water and oxidizer. These components are present in amounts such that the concentrate can be diluted at very high dilution ratios, without affecting the polishing performance.
