  • Monolithic integrated circuit die heater and methods for using same
    Patent number: 6046433
    Abstract: The invention provides an integrated circuit die containing a metal heater resistor. In an embodiment of the invention, the metal heater resistor is disposed around the periphery of the die, with one end of the metal heater resistor connected to a first bond pad, and the other end of the heater resistor connected to a second bond pad. In alternative embodiments, metal-to-substrate contacts disposed along the heater resistor between the first and second ends provide improved thermal contact between the heater resistor and the die substrate. In other alternative embodiments, the metal heater resistor is disposed around the periphery of a circuit whose temperature coefficient is to be measured, such as a voltage reference circuit that is included as part of a larger integrated circuit containing other circuitry.
