The mechanism of the FA/O chelating agent in the process of chemical mechanical polishing(CMP) is introduced. CMP is carried on a 300 mm copper film. The higher polishing rate and lower surface roughness are acquired due to the action of an FA/O chelating agent with an extremely strong chelating ability under the condition of low pressure and low abrasive concentration during the CMP process. According to the results of several kinds of additive interaction curves when the pressure is 13.78 kPa, flow rate is 150 mL/min, and the rotating speed is55/60 rpm, it can be demonstrated that the FA/O chelating agent plays important role during the CMP process.
