    • 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.

    • Provided is a small ion implanting apparatus for manufacturing single crystalline films, with stable parallelism of ion beams and high controllability of density distribution. The ion implanting apparatus extracts hydrogen ions or rare gas ions from an ion source (12), desired ions (B) are selected from a first fan-shaped electromagnet (14), the ions (B) are scanned by a scanner (16), the ions (B) are parallelized by a second fan-shaped electromagnet (18) and implanted into a substrate (20), and a single crystalline film is manufactured. The ion source (12) is arranged in the vicinity of an inlet side focal point (F1) of the first fan-shaped electromagnet (14). When the opening of the extracting section of the ion source (12) is made circular and that a deflection plane in the first fan-shaped electromagnet (14) matches with the inlet side focal point on a plane vertical to the deflection plane, the spot shape of the ion beam (B) after passing through the first fan-shaped electromagnet (14) becomes circular and completely parallel on the two planes.
