A method of clamping/declamping a semiconductor wafer on an electrostatic chuck in ambient air includes disposing the semiconductor wafer at a predetermined distance above a dielectric surface of the electrostatic chuck having one or more electrodes and applying a first voltage greater than a predetermined threshold to the one or more electrodes of the electrostatic chuck for a first time period. The method includes reducing the first voltage to a second voltage substantially equal to a self bias potential of the semiconductor wafer after the first time period. The method includes maintaining the second voltage for a second time period and adjusting the second voltage to a third voltage characterized by a polarity opposite to that of the first voltage and a magnitude smaller than the predetermined threshold. The method includes reducing the third voltage to a fourth voltage substantially equal to the second voltage after a third time period.
