    Abstract: 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.
