发明名称 Slurry composition with high planarity and CMP process of dielectric film using the same
摘要 Disclosed herein are a CMP slurry composition with high-planarity and a CMP process for polishing a dielectric film using the same. More specifically, a CMP slurry composition with high-planarity includes a carbon compound having tens of thousands of carboxyl groups and having a molecular weight ranging from hundreds of thousands to millions, an abrasive, and water. A CMP process for polishing a dielectric film utilizes the disclosed slurry composition. The slurry composition enables complete and overall planarization of the dielectric film by polishing the part of the film having a higher step difference through CMP process. Accordingly, the disclosed slurry composition is useful for the CMP process of all semiconductor devices including those having ultrafine patterns.
