  • Method and apparatus for the localized reduction of the lifetime of charge carriers, particularly in integrated electronic devices
    Patent number: 6168981
    Abstract: A method and apparatus for the localized reduction of the lifetime of charge carriers in integrated electronic devices. The method comprises the step of implanting ions, at a high dosage and at a high energy level, of a noble gas, preferably helium, in the active regions of the integrated device so that the ions form bubbles in the active regions. A further thermal treatment is performed after the formation of bubbles of the noble gas in order to improve the structure of the bubbles and to make the noble gas evaporate, leaving cavities in the active regions.
    Type: Grant
    Filed: January 6, 1999
    Date of Patent: January 2, 2001
    Assignee: Consorzio per la Ricerca sulla Microelettronica nel Mezzogiorno
    Inventors: Anna Battaglia, Piergiorgio Fallica, Cesare Ronsisvalle, Salvatore Coffa, Vito Raineri
