ABSTRACT:
There is proposed a polishing method. The method includes feeding a slurry onto a polishing pad, press-contacting a semiconductor substrate held on a polishing head with the polishing pad, the semiconductor substrate having an organic film thereon, and chemically mechanically polishing the organic film by repeating a sequence of rotation and halt of rotation of the polishing pad and the polishing head.
