Abstract

See full text

There is disclosed 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, and dropping a slurry onto the polishing pad to polish the organic film, the slurry being selected from the group consisting of a first slurry and a second slurry, the first slurry comprising a resin particle having a functional group selected from the group consisting of an anionic functional group, a cationic functional group, an amphoteric functional group and a nonionic functional group, and having a primary particle diameter ranging from 0.05 to 5 μm, the first slurry having a pH ranging from 2 to 8, and the second slurry comprising a resin particle having a primary particle diameter ranging from 0.05 to 5 μm, and a surfactant having a hydrophilic moiety.
