Abstract
A method for detecting particle agglomeration in CMP slurries. In accordance with an implementation of the invention, a CMP slurry is tested for abrasive particle agglomeration by applying an ultra high shearing force to the slurry and analyzing its rheological behavior. Through the comparison of slurry rheological behavior, implementations of the invention make it possible to detect particle agglomeration in a slurry and to distinguish between fresh and aged slurries.
