ABSTRACT:
An infrared sensor is provided in a burn-in chamber. The surface temperatures of two or more semiconductor devices are measured by the sensor. A control unit calculates the internal temperatures of the semiconductor devices based on the thermal resistance values of the semiconductor device packages and controls the temperature inside the burn-in chamber so that the average of the internal temperatures is brought to a desired temperature by using a temperature controller. Further, an acceleration coefficient is obtained based on the internal temperatures, a burn-in time is determined based on the acceleration coefficient and a preliminarily given accelerated period, and a burn-in acceleration test is conducted. Moreover, when a defective semiconductor is found, the defective portion of the defective semiconductor device is specified based on the surface temperature distribution of the semiconductor device measured by the infrared sensor.
