System and method to control PVD deposition uniformity
Last updated:
Abstract:
A physical vapor deposition chamber comprising a rotating substrate support having a rotational axis, a first cathode having a radial center positioned off-center from a rotational axis of the substrate support is disclosed. A process controller comprising one or more process configurations selected from one or more of a first configuration to determine a rotation speed (v) for a substrate support to complete a whole number of rotations (n) around the rotational axis of the substrate support in a process window time (t) to form a layer of a first material on a substrate, or a second configuration to rotate the substrate support at the rotation speed (v).
