    摘要: A first chemical mechanical polishing (CMP) slurry includes a polishing agent, an oxidant, a pH control additive, and an oxide film removal retarder which reduces a removal rate of the silicon oxide film. A second chemical mechanical polishing (CMP) slurry includes a polishing agent, an oxidant, a pH control additive, an oxide film removal retarder which reduces a removal rate of silicon oxide, and a defect prevention agent which inhibits scratch defects and/or corrosion defects at a surface of an aluminum film. In a one-step CMP process, either of the first or second slurry is used throughout CMP of an aluminum layer until an upper surface of an underlying silicon oxide layer is exposed. In a two-step CMP process, the first slurry is used in an initial CMP of the aluminum layer, and then the second slurry is used in a subsequent CMP until the upper surface of the underlying silicon layer is exposed.

    摘要: A method for isolating SAC pads of a semiconductor device, including determining a chemical mechanical polishing process time necessary to isolate the SAC pads a desired amount by referring to a relationship equation between the extent of isolation of the self-aligned contact pads and the chemical-mechanical polishing process time. The chemical mechanical polishing process is performed for the determined process time on the semiconductor device to isolate the self-aligned contact pads the desired amount. The relationship equation is determined using a test semiconductor device.
