    摘要: A chemical mechanical polishing (CMP) method is disclosed for use in the fabrication of a semiconductor device having dense and sparse regions. The method uses an abrasive stop layer formed on the dense and sparse regions to control polishing of a material layer formed on the abrasive stop layer by a rigid, fixed abrasive polishing pad.
