The present disclosure is directed to a material layer deposition system. The material layer deposition system includes a wafer pedestal configured to support at least one wafer within a confinement shield structure and a target carrier structure positioned above the wafer pedestal at an opposite side of the confinement shield structure. The target carrier structure is configured to support a sputtering target. The material layer deposition system further includes a collimator disposed within the confinement shield structure between the wafer pedestal and the target carrier structure, an electrical power source coupled to the collimator to supply electrical power, and a control system configured to control the electrical power source coupled to the collimator.
