Abstract: The present invention provides a method of preventing the build-up of polishing material within low areas of a substrate during polishing. Following the blanket deposition of a first layer, a selectively removable material is deposited over the first layer, wherein the selectively removable material fills the low areas. A surface of the substrate is polished removing the excess first layer and selectively removable material from the surface, leaving the first layer and selectively removable material within the low area. Following polishing, the selectively removable material is removed from the low areas prior to the deposition of a second layer.
