  • Patent number: 6989315
    Abstract: An ion implantation system for producing silicon wafers having relatively low defect densities, e.g., below about 1×106/cm2, includes a fluid port in the ion implantation chamber for introducing a background gas into the chamber during the ion implantation process. The introduced gas, such as water vapor, reduces the defect density of the top silicon layer that is separated from the buried silicon dioxide layer.
    Type: Grant
    Filed: June 19, 2001
    Date of Patent: January 24, 2006
    Assignee: Ibis Technology, Inc.
    Inventors: Robert Dolan, Bernhard Cordts, Marvin Farley, Geoffrey Ryding
