发明名称 POLISHING METHOD AND POLISHING DEVICE
摘要 A polishing method includes: mounting a wafer on a fixed abrasive polishing pad located on a polishing platen; delivering a polishing slurry to the fixed abrasive polishing pad to polish the wafer; and adsorbing abrasive particles generated during the polishing process with an electrode. The electrode has a polarity opposite to a polarity of charges of the abrasive particles. A polishing device includes a polishing platen, a fixed abrasive polishing pad, a slurry pipeline and a polarity changer having an electrode. Therefore, the abrasive particles generated during the polishing process are removed, which prevents the wafer from being scratched, thereby increasing wafer yield and improving efficiency.
