Abstract
In a semiconductor device comprising a semiconductor chip on which semiconductor elements are formed, the semiconductor device further comprises a thermal resistance detector for detecting an increase of thermal resistance of a heat radiating path which is provided to radiate the heat generated in the semiconductor device during operation, and a thermal resistance detection result output circuit for outputting a result of a detection by the thermal resistance detector to an output of the semiconductor device. The semiconductor device can detect at the early stage the increase of the thermal resistance of the heat radiating path, and the deterioration of the semiconductor device due to the crack in the solder layer bonding the chip mounting insulation substrate and heat sink during the operation of the device.
