Abstract:
An apparatus and methods for plasma-based sputtering deposition using a direct current power supply is disclosed. In one embodiment, a plasma is generated by connecting a plurality of electrodes to a supply of current, and a polarity of voltage applied to each of a plurality of electrodes in the processing chamber is periodically reversed so that at least one of the electrodes sputters material on to the substrate. And an amount of power that is applied to at least one of the plurality of electrodes is modulated so as to deposit the material on the stationary substrate with a desired characteristic. In some embodiments, the substrate is statically disposed in the chamber during processing. And many embodiments utilize feedback indicative of the state of the deposition to modulate the amount of power applied to one or more electrodes.
