  • Method for thermal impedance evaluation of packaged semiconductor components
    Patent number: 5927853
    Abstract: A method for evaluating the thermal impedance of packaged semiconductor chips. A measuring apparatus includes a thermostatic bath filled with a dielectric liquid and a temperature sensor for measuring the temperature of the bath. The semiconductor chip is subjected to a calibration step followed by a thermal response measurement step. Increasing the power pulse length allows measurement of the steady-state junction-to-case thermal resistance. The measuring apparatus and method is further used for tracing in-situ degradation of packaged semiconductor chips due to power cycling.
    Type: Grant
