Patent ID: 8685857

Claim:
A chemical mechanical polishing method of an organic film comprising: forming the organic film above a semiconductor substrate; contacting the organic film formed above the semiconductor substrate with a polishing pad attached to a turntable; subjecting the organic film to a two-step polishing including subjecting the organic film to a first polishing to flatten a surface of the organic film with generation of organic shavings by feeding a dispersion containing a resin particle having a primary particle diameter ranging from 0.05 to 5 Î¼m to the polishing pad; and after the first polishing, subjecting the organic film to a second polishing subsequent to the first polishing by feeding a solution containing a surfactant having a hydrophilic moiety to the polishing pad which has been subjected to the first polishing, thereby hydrophilizing a surface of the polishing pad to discharge the organic shavings on the surface of the polishing pad, the solution containing the surfactant being different in composition than the dispersion containing the resin particle, the surface of the organic film being flattened without the organic shavings remained.
