SYSTEMS AND METHODS FOR IN-SITU ETCHING PRIOR TO PHYSICAL VAPOR DEPOSITION IN THE SAME CHAMBER
The present invention provides a method for in-situ etching of a wafer prior to physical vapor deposition, the method comprising the following steps. A sputtering chamber is provided, the sputtering chamber being collectively defined by a wafer handling apparatus and a magnetron. The wafer is placed into the sputtering chamber. A gas is introduced into the sputtering chamber such that the gas is separated into a plasma, wherein the plasma includes gas ions. A first negative potential is applied to the wafer using a wafer chuck of the wafer handling apparatus while a second negative potential is simultaneously applied to a sputtering target of the magnetron, wherein simultaneous application of the first negative potential to the wafer and the second negative potential to the sputtering target causes gas ions to eject material from the wafer and the sputtering target of the magnetron such that ejected material from the wafer and the sputtering target is collected onto a shield defined by the sputtering chamber.
