Abstract
A method of eliminating charging resulting from plasma processing a semiconductor wafer comprising the steps of plasma processing the semiconductor wafer in a manner that may result in topographically dependent charging and exposing, during at least a portion of a time in which the semiconductor wafer is being plasma processed, the semiconductor wafer to particles that remove charge from the semiconductor wafer and reduce topographically dependent charging.
