Abstract:
1. A high power impulse magnetron sputtering apparatus comprising: a vacuum chamber; a magnetron target positioned in said vacuum chamber; a substrate positioned inside said vacuum chamber and away from said magnetron target; a magnetron anode positioned in said vacuum chamber, said anode being connected to an electrical ground; a field coil positioned between said magnetron target and said substrate and configured to generate a magnetic field when energized; a pulsed coil power supply connected to said field coil; a pulsed magnetron high voltage power supply connected to said magnetron target and said magnetron anode; a synchronization line connection between said pulsed magnetron high voltage power supply and said pulsed coil power supply; a substrate bias voltage power supply connected to said substrate and configured to generate an electric field to direct and focus ionized sputter material onto said substrate; and, a coil bias power supply connected to said field coil and to said magnetron anode and configured to apply an electric voltage bias to said field coil to assist the generated magnetic field to direct and focus ionized sputter vapors onto said substrate.
