    Abstract: Embodiments of the invention generally provide a processing chamber used to perform a physical vapor deposition (PVD) process and methods of depositing multi-compositional films. The processing chamber may include: an improved RF feed configuration to reduce any standing wave effects; an improved magnetron design to enhance RF plasma uniformity, deposited film composition and thickness uniformity; an improved substrate biasing configuration to improve process control; and an improved process kit design to improve RF field uniformity near the critical surfaces of the substrate. The method includes forming a plasma in a processing region of a chamber using an RF supply coupled to a multi-compositional target, translating a magnetron relative to the multi-compositional target, wherein the magnetron is positioned in a first position relative to a center point of the multi-compositional target while the magnetron is translating and the plasma is formed, and depositing a multi-compositional film on a substrate in the chamber.
