摘要: The disclosure relates to a method for manufacturing a semiconductor device by performing a planarization process including a first CMP process using a slurry including 0.05˜0.5 wt % CeO2 or MnO2 as an abrasive and a second CMP process using a slurry including SiO2 as the other abrasive regardless of order of the processes. The CMP process is performed using the first slurry having a high polishing speed in the middle of the wafer and the second slurry having a high polishing speed at the edge of the wafer, thereby decreasing the processing cost and securing the process margin to secure yield and reliability of devices
