Abstract: Planarization methods include depositing a mask material on top of an overburden layer on a semiconductor wafer. The mask material is planarized to remove the mask material from up areas of the overburden layer to expose the overburden layer without removing the mask material from down areas. The exposed overburden layer is wet etched and leaves a thickness remaining over an underlying layer. Remaining portions of the mask layer and the exposed portions of the overburden layer are planarized to expose the underlying layer.
