1. A heat-trimmable resistor comprising:

  • a thin-film resistive element configured as a resistor that is connected to or connectable to a circuit;

    a thin-film heating region proximal at least a portion of the thin-film resistive element; and

    an electrically-conductive material in electrical contact with the thin-film heating region and having lower sheet resistance than the thin-film heating region that connects the thin-film heating region to a conductive interconnect.
