  • Publication number: 20070132064
    Abstract: An electrical resistor structure overlies a substrate and comprises a composite resistor having a first resistor of relatively low resistance and a second resistor of relatively high resistance overlying the first resistor. First and second electrodes make contact with the composite resistor at spaced locations, and a bond pad overlies the second resistor at a position between the electrodes. A metallized fiber is soldered a to a metal bond pad by providing a stacked resistor structure beneath the bond pad, disposing a solder preform over the bond pad, disposing the metallized fiber over the bond pad, and flowing a current through the stacked resistor structure. The stacked resistor structure, when subjected to a current flowing generally along a first axis, is characterized by a temperature profile that has first and second peaks on either side of the bond pad.
