  • Patent number: 8338806
    Abstract: A processing system is provided for irradiating a substrate with a gas cluster ion beam (GCIB). The system includes a nozzle for forming and emitting gas cluster beams through a nozzle outlet, and a stagnation chamber that is located upstream of and adjacent the nozzle. The stagnation chamber has an inlet, and the nozzle is configured to direct a single gas cluster beam toward the substrate. An ionizer is positioned downstream of the outlet and is configured to ionize the gas cluster beam to form the GCIB. The system also includes a gas supply that is in fluid communication with the inlet of the stagnation chamber, and which includes a gas source and a valve located between the gas source and the nozzle for controlling flow of a gas between the gas source and the nozzle.
    Type: Grant

  • Patent number: 7173260
    Abstract: An ion implanter having a source, a workpiece support and a transport system for delivering ions from the source to an ion implantation chamber that contains the workpiece support. The implanter includes one or more removable inserts mounted to an interior of either the transport system or the ion implantation chamber for collecting material entering either the transport system or the ion implantation chamber due to collisions between ions and the workpiece within the ion implantation chamber during ion processing of the workpiece. A temperature control coupled to the one or more removable inserts for maintaining the temperature of the insert at a controlled temperature to promote formation of a film on said insert during ion treatment due to collisions between ions and said workpiece.
