Acidic polishing composition with enhanced defect suppression and method of polishing a substrate |
| abstract |
An acidic chemical mechanical polishing composition is disclosed comprising colloidal silica abrasive particles having a positive zeta potential and an alkoxysilane succinic anhydride compound selected to enhance reduction of defects on dielectric materials such as substrates of silica and silicon nitride. Also disclosed are methods for polishing a substrate with the acidic chemical mechanical polishing composition to remove some of the dielectric materials, such as silicon dioxide and silicon nitride. |
