Abstract:
Apparatus and methods for improving film uniformity in a physical vapor deposition (PVD) process are provided herein. In some embodiments, a PVD chamber includes a pedestal disposed within a processing region of the PVD chamber, the pedestal having an upper surface configured to support a substrate thereon, a first motor coupled to the pedestal, a lid assembly comprising a first target, a first magnetron disposed over a portion of the first target, and in a region of the lid assembly that is maintained at atmospheric pressure, a first actuator configured to translate the first magnetron in a first direction, a second actuator configured to translate the first magnetron in a second direction, and a system controller that is configured to cause the first magnetron to translate along at least a portion of a first path by causing the first actuator and second actuator to simultaneously translate the first magnetron.
