WebbColloidal Silica is a slurry that is used for final polishing in a number of industries. Unlike standard abrasive slurries, colloidal silica falls into a category called C.M.P, or Chemical Mechanical Polishing. It’s common … Webbactive slurries will have a higher amount of recess due to the wet etching action of the slurry. Dishing occurs when the polishing pad under the pressure of polishing, is able to deform into the damascene structure and polish it below the field area. The amount of dishing that occurs is related to the polishing pad characteristics, the grading and reporting mcps
