Abstract:
In some embodiments, the present disclosure relates to an integrated circuit (IC) having parallel conductive paths between a BEOL interconnect layer and a middle-end-of-the-line (MEOL) structure, which are configured to reduce a parasitic resistance and/or capacitance of the IC. The IC comprises source/drain regions arranged within a substrate and separated by a channel region. A gate structure is arranged over the channel region and a MEOL structure is arranged over one of the source/drain regions. A conductive structure is arranged over and in electrical contact with the MEOL structure. A first conductive contact is arranged between the MEOL structure and an overlying BEOL interconnect wire (e.g., a power rail). A second conductive contact is configured to electrically couple the BEOL interconnect wire and the MEOL structure along a conductive path extending through the conductive structure, thereby forming parallel conductive paths between the BEOL interconnect layer and the MEOL structure.
