Chemical mechanical polishing (CMP) is performed on the oxide layer until the medium material layer is exposed. CMP is then performed until the patterned etch stop layer is exposed and a planarized oxide layer is formed. Because the medium material layer has a higher removal rate during CMP than the oxide layer, occurrences of the dishing phenomenon are reduced. A slurry including an anionic surfactant is used to increase the CMP removal ratio of the medium material layer to the oxide layer.11-13-2008
