Doped electrical current-carrying conductive material
Abstract
Abstract THIS INVENTION PROVIDES A MEANS OF INCREASING THE TIMETO-FAILURE OF DOPED CONDUCTIVE STRIPES BY DEPOSITING REGIONS OF DOPANT REJUVENANT UPON REGIONS IN THE STRIPE WHEREIN DOPANT DEPLETION IS MOST APT TO OCCUR UNDER CURRENT STRESS. THIS INVENTION ALSO PROVIDES A MEANS OF REJUVENATING REGIONS WHEREIN DOPANT DEPLETION HAS OCCURRED BY PERIODICALLY APPLYING HEAT TO A MICROELECTONIC CONFIGURATION CONTAINING DOPED CONDUCTIVE THIN FILMS FOR INTERCONNECTION PURPOSES, SAID THIN FILMS CONTAINING LOCAL, DISCONTINUOUS DEPOSITS OF DOPANT REJUVENANT OVER REGIONS WITHIN THE FILM WHEREIN TEMPERATURE GRADIENTS OR DIFFUSION BARRIERS ARISE UNDER CURRENT STRESS RESULTING IN MASS FLUX DIVERGENCES IN SAID REGIONS, I.E., A RESULTANT EFFLUX OF DOPANT FROM SAID REGION. APPLICATION OF HEAT IN THIS MANNER PERMITS DIFFUSION OF DOPANT REJUVENANT FROM THE LOCALIZED DOPANT REJUVENANT SOURCE INTO THE REGION FROM WHICH DOPANT HAS MIGRATED DURING SERVICE, THEREBY REJUVENATING THE MICROELECTRONIC CONFIGURATION AND ENABLING ITS CONTINUED USE.
