Abstract

In an example embodiment a method of processing a substrate includes forming a plasma in a plasma chamber and using charged grids to form an ion beam and to thereby accelerate ions from the plasma chamber to a processing chamber. An auxiliary heater, which may be a radiant heater, may be used to pre-heat a grid to a saturation state to accelerate heating and concomitant distortion of the grid. A process recipe may pre-compensate for distortion of the grid.
