    Abstract: The service lifetime of an ion source is enhanced or prolonged by the source having provisions for in-situ etch cleaning of the ion source and of an extraction electrode, using reactive halogen gases, and by having features that extend the service duration between cleanings. The latter include accurate vapor flow control, accurate focusing of the ion beam optics, and thermal control of the extraction electrode that prevents formation of deposits or prevents electrode destruction. An apparatus comprised of an ion source for generating dopant ions for semiconductor wafer processing is coupled to a remote plasma source which delivers F or Cl ions to the first ion source for the purpose of cleaning deposits in the first ion source and the extraction electrode. These methods and apparatus enable long equipment uptime when running condensable feed gases such as sublimated vapor sources, and are particularly applicable for use with so-called cold ion sources. Methods and apparatus are described which enable long equipment uptime when decaborane and octadecaborane are used as feed materials, as well as when vaporized elemental arsenic and phosphorus are used, and which serve to enhance beam stability during ion implantation.

    Abstract: Thermal control is provided for an extraction electrode of an ion-beam producing system that prevents formation of deposits and unstable operation and enables use with ions produced from condensable vapors and with ion sources capable of cold and hot operation. Electrical heating of the extraction electrode is employed for extracting decaborane or octadecaborane ions. Active cooling during use with a hot ion source prevents electrode destruction, permitting the extraction electrode to be of heat-conductive and fluorine-resistant aluminum composition. The service lifetime of the system is enhanced by provisions for in-situ etch cleaning of the ion source and extraction electrode, using reactive halogen gases, and by having features that extend the service duration between cleanings, including accurate vapor flow control and accurate focusing of the ion beam optics. A remote plasma source delivers F or Cl ions to the de-energized ion source for the purpose of cleaning deposits in the ion source and the extraction electrode. These techniques enable long equipment uptime when running condensable feed gases such as sublimated vapors, and are particularly applicable for use with so-called cold ion sources and universal ion sources. Methods and apparatus are described which enable long equipment uptime when decaborane and octadecaborane are used as feed materials, as well as when vaporized elemental arsenic and phosphorus are used, and which serve to enhance beam stability during ion implantation.
