| 摘要 |
The present invention relates to a Chemical Mechanical Polishing (CMP) method of a semiconductor device. According to the method, a metal layer is formed over a semiconductor substrate in which an edge region define. A passivation layer is formed on the metal layer. The passivation layer formed in the edge region is etched in order to expose the metal layer. The exposed metal layer is removed through etching. The metal layer is polished by performing a CMP process, thus forming a metal line.
