发明名称 METHOD TO REDUCE PLASMA CHARGE DAMAGE FROM HIGH DENSITY PLASMA CHEMICAL VAPOR DEPOSITION (HDP-CVD) PROCESS
摘要 A method of processing wafers within a high density plasma chemical vapor deposition chamber comprises setting a plasma charge level within the chamber at a zero power level and, while the plasma charge level within the chamber is at the zero power level, moving a wafer into the chamber. Then, the method sets the plasma charge level to a second power level higher than zero after the wafer is moved into the chamber and performs a chemical vapor deposition process on the wafer within the chamber. After performing the chemical vapor deposition process, the method moves the wafer to a non-plasma region within the chamber. Then, after moving the wafer to the non-plasma region within the chamber, the method again sets the plasma charge level within the chamber at the zero power level. Next, after setting the plasma charge level within the chamber at the zero power level, the method opens the door of the chamber and, while the plasma charge level within the chamber is at the zero power level, the method removes the wafer from the chamber through the door of the chamber.
