Abstract
An electrically re-programmable fuse (eFUSE) device for use in integrated circuit devices includes an elongated heater element, an electrically insulating liner surrounding an outer surface of the elongated heater element, corresponding to a longitudinal axis thereof, leaving opposing ends of the elongated heater element in electrical contact with first and second heater electrodes. A phase change material (PCM) surrounds a portion of an outer surface of the electrically insulating liner, a thermally and electrically insulating layer surrounds an outer surface of the PCM, with first and second fuse electrodes in electrical contact with opposing ends of the PCM. The PCM is encapsulated within the electrically insulating liner, the thermally and electrically insulating layer, and the first and second fuse electrodes.
