发明名称 CMP SLURRY AND METHOD FOR POLISHING SEMICONDUCTOR WAFER USING THE SAME
摘要 <p>Disclosed is a CMP slurry in which a compound having a weight-average molecular weight of 30-500 and containing a hydroxyl group (OH), a carboxyl group (COOH), or both, is added to a CMP slurry comprising abrasive particles and water and having a first viscosity, so that the CMP slurry is controlled to have a second viscosity 5-30% lower than the first viscosity. Also disclosed is a method for polishing a semiconductor wafer using the CMP slurry. According to the disclosed invention, the agglomerated particle size of abrasive particles in the CMP slurry can be reduced, while the viscosity of the CMP slurry can be reduced and the global planarity of wafers upon polishing can be improved. Thus, the CMP slurry can be advantageously used in processes for manufacturing semiconductor devices requiring fine patterns and can improve the reliability and production of semiconductor devices through the use thereof in semiconductor processes.</p>
