The tribological and kinetic attributes of 300-mm copper chemical mechanical planarization process were characterized in this study. Boundary lubrication was the dominant tribological mechanism for Cabot Microelectronics Corporation DlOO concentrically grooved pad. For Dow Electronic Materials IClOOO K-groove pad, the tribological mechanism transitioned from boundary lubrication to partial lubrication. For both pads, copper removal rate exhibited highly non-Prestonian behavior. A two-step modified Langmuir-Hinshelwood model was used to simulate copper removal rate, wafer surface reaction temperature, as well as chemical and mechanical rate constants. The simulated copper removal rates agreed very well with the experimental values. The simulated chemical rate constant to mechanical rate constant ratios indicated that the IC1000 generally produced a more mechanically controlled removal mechanism in this study.
