Abstract
A method and control system are provided for depositing a layer in a sputter-deposition system having a target cathode. A first dependence relationship of a deposition rate of the layer on an operating parameter, selected from cathode voltage, cathode current, and cathode power, is provided prior to deposition of the layer. A second dependence relationship of the operating parameter on time is measured during deposition of the layer, while a different operating parameter, also selected from cathode voltage, cathode current, and cathode power, is held substantially constant. On the basis of the first and second dependence relationships, a deposition time for the layer is dynamically determined during deposition of the layer.
