Abstract:
1. A cleaning material to remove contaminants from a semiconductor substrate surface, comprising: a cleaning liquid; a plurality of solid components being greater than zero and less than 3% of the cleaning material, the plurality of solid components being dispersed in the cleaning liquid, wherein the plurality of solid component interact with at least some of contaminants on the semiconductor substrate surface to remove the contaminants from the substrate surface; and polymers of a polymeric compound, the polymers being greater than zero and less than 500 ppm, wherein the polymers become soluble in the cleaning liquid and form the cleaning material with the cleaning liquid and the plurality of solid components, and wherein the solubilized polymers having long polymer chains capture and entrap solid components and contaminants in the cleaning liquid.
