    摘要: Polishing pads used in CMP machines are consumable components that are typically replaced after a specific number of wafers have been processed. The life of a polishing pad is optimized by controlling the rate of material removal from the polishing pad by the conditioning disk. The conditioning disk removes enough material so the polishing surface can properly process the wafers but does not remove any excess material. Preventing excess material removal extends the life of the polishing pad. During CMP processing, the controller receives data concerning the torque applied to the conditioning disk and the torque applied to the arm to sweep the conditioning disk across the polishing pad. Based upon the detected operating conditions, the system can predict the rate of material removal and adjust the forces applied to the conditioning disk so that the life of the polishing pad is optimized.

    摘要: A conditioning process includes rotating a polishing pad about an axis of rotation, conditioning the polishing pad by sweeping an abrasive disk in a path across a surface of the polishing pad between an inner radial distance from the axis of rotation and an outer radial distance from the axis of rotation, sweeping a sensor across the polishing pad while conditioning the polishing pad, measuring a thickness of the polishing pad at a plurality of positions between the inner radial distance and the outer radial distance with the sensor, and adjusting at least one of a dwell time or a pressure of the abrasive disk against the polishing pad for a portion of the path based on measurements of the thickness by the sensor such that the polishing pad wears to a more uniform thickness than without such adjustment.

    摘要: Apparatus and methods for conditioning a polishing pad include a base, an arm pivotally coupled to the base and adapted to support a conditioning disk, and an actuator coupled to the base and the arm. The actuator is adapted to cause the arm to press the conditioning disk against the polishing pad with a linearly variable amount of force. A first force is produced with the actuator. The first force is scaled by a linearly variable amount to a second force that is applied to the polishing pad by a conditioning disk. Numerous other aspects are disclosed.

    摘要: Embodiments of the invention relate to a gas delivery system. The gas delivery system includes a fast gas exchange module in fluid communication with one or more gas panels and a process chamber. The fast gas exchange module has first and second sets of flow controllers and each of first and second sets of flow controllers has multiple flow controllers. The flow controller is configured such that each of the flow controllers in the first and second sets of the flow controllers is independently operated to selectively open to divert gas to the process chamber or an exhaust. The first and second sets of flow controllers are operated for synchronized switching of gases in a pre-determined timed sequence of flow controller actuation. The invention enables fast switch of resultant gas flow in the process chamber while having individual flow controller operated at lower switching speed to provide longer service life.
