    Abstract: A plasma chamber for a UV light source includes a plasma generation region that defines a plasma confinement region. A port is positioned adjacent to a side of the plasma generation region that allows generated light to pass out of the chamber. A high voltage region is coupled to the plasma generation region. A grounded region is coupled to the high voltage region that defines an outer surface configured to be coupled to the ground and is dimensioned for receiving a surrounding inductive core. A width of the high voltage region is greater than the width of the grounded region.

  • Patent number: 8143790
    Abstract: A method for producing light includes introducing an ionizable medium for generating a plasma into a chamber. The method also includes applying at least one pulse of energy to a magnetic core that surrounds a portion of a plasma discharge region within the chamber such that the magnetic core delivers power to the plasma which forms a secondary of a transformer according to Faraday's law of induction. The plasma has a localized high intensity zone.

  • Patent number: 7238266
    Abstract: The invention relates to apparatus and methods for generating and recycling fluorine. The applicants recognized that a fluorine separator, used either alone or in combination with a plasma generator can produce sufficient quantities of fluorine at its point of use for thin film processing. The fluorine separator can take the form of a condenser, a membrane separation device, a fluorine ion conductor comprising a solid electrolyte, or a combination of the foregoing. In some embodiments, reaction products comprising fluorine are passed to the fluorine separator. In other embodiments, separated fluorine is passed, either alone or in conjunction with additional feed stock comprising fluorine, to a plasma generator. The fluorine separator allows fluorine to be recycled and waste products to be eliminated from the system.

    Abstract: An ion storage system is described that includes an ion trap that defines a volume for storing a plurality of ions. A radio frequency (RF) generator is electromagnetically coupled to the volume defined by the ion trap. The RF generator generates an RF electrical field that stores the plurality of ions in the ion trap. A switching device terminates the RF electrical field, which ejects the plurality of ions from the ion trap. An ion detector detects at least a portion of the plurality of ions that are ejected from the ion trap.
