Abstract:
A chemical mechanical polish planarizing method for forming a chemical mechanical polish planarized layer, comprising the steps:providing a substrate; forming over the substrate a first inorganic layer; forming over the first inorganic layer an organic material layer; forming over the organic material layer a second inorganic layer; patterning through the second inorganic layer, the organic material layer and the first inorganic layer to form at least one aperture; forming a conductor layer over the second inorganic layer to at least fill the at least one aperture; planarizing the conductor layer to form a planarized conductor layer portion within the at least one aperture, the organic material layer functioning as a pressure compensating layer which compensates for the planarizing pressure employed during planarization of the conductor layer whereby the planarized conductor layer portion is formed with enhanced surface planarity uniformity.
