Abstract:
A system and method for processing a wafer includes a charge neutralization system. The wafer processing system includes a wafer measuring device that can measure characteristics of a surface of the semiconductor wafer. One or more wafer processing stations perform a chemical mechanical polish (CMP) process on the wafer surface. A desica cleaning station can clean and dry the semiconductor wafer. The wafer processing system further includes a charge neutralizing device that can alter a surface charge of the wafer surface.
