In the present paper, a chip with a Pt-based RTD that functions as a heater and sensor is tested under serial power loads, and infrared (IR) thermal imaging system is adopted to obtain the thermal measurement. Comparisons of the hotspot temperatures of the chip obtained by RTD and IR methods have been made, where different surfaces of the chip were observed by the IR camera. Combing with the heat conduction law, the IR results of the test chip with surface preparation showed quite a good agreement with the RTD data, verifying the validation of the IR analysis method.
