A plasma processing method and apparatus are provided in which current spikes associated with application of a voltage to an electrostatic chuck (ESC) are minimized or reduced when the processing plasma is present. According to an example, the voltage is applied to the ESC after the processing plasma is struck, however the voltage is ramped or increased in a step-wise manner to achieve the desired final ESC voltage. In an alternate embodiment, the ESC voltage is at least partially applied before striking of the plasma for processing the wafer. By reducing current spikes associated with application of the voltage to the ESC during the presence of the processing plasma, transfer or deposition of particles on the wafer can be reduced.
