    Abstract: Systems and methods for are disclosed. One method includes providing at least a first electrode, a second electrode, and a third electrode and using each of at least two, separate and different, target materials in connection with the three electrodes to enable sputtering. The method also includes applying a first voltage at the first electrode that alternates between positive and negative relative to the second electrode during each of multiple cycles and applying a second voltage to the third electrode that alternates between positive and negative relative to the second electrode during each of the multiple cycles.

    Abstract: Systems and methods for arc handling in plasma processing operations are disclosed. The method includes providing current with a power supply to a plasma load at a first voltage polarity and energizing an energy storage device so when it is energized, the energy storage device applies a reverse polarity voltage that has a magnitude that is as least as great as the first voltage polarity. When an arc is detected, power is applied from the energy storage device to the plasma load with a reverse polarity voltage that has a polarity that is opposite of the first voltage polarity, the application of the reverse polarity voltage to the plasma load decreases a level of the current that is provided to the plasma load.

    Abstract: A system and method for single magnetron sputtering are described. One example includes a system having a power supply, a plasma chamber enclosing a substrate, an anode, and a target for depositing a thin film material on the substrate. This example also has a datastore with uncoated anode characterization data and an anode sputtering adjustment system including an anode analysis component to generate a first health value. The first health value is indicative of whether the anode is coated with a dielectric material. This example also has an anode power controller to receive the first health value and provide an anode-energy-control signal to the pulse controller of the pulsed DC power supply to adjust a second anode sputtering energy relative to a first anode sputtering energy to eject at least a portion of the dielectric material from the anode.

    Abstract: A sputtering system and method are disclosed. The system has at least one dual magnetron pair having a first magnetron and a second magnetron, each magnetron configured to support target material. The system also has a DMS component having a DC power source in connection with switching components and voltage sensors. The DMS component is configured to independently control an application of power to each of the magnetrons, and to provide measurements of voltages at each of the magnetrons. The system also has one or more actuators configured to control the voltages at each of the magnetrons using the measurements provided by the DMS component. The DMS component and the one or more actuators are configured to balance the consumption of the target material by controlling the power and the voltage applied to each of the magnetrons, in response to the measurements of voltages at each of the magnetrons.
