The image of the device enlarged by the microscope, is input to a TV camera via a photomultiplier , and then displayed on a display. A controller controls these units and stores this image from the TV camera in its internal memory. Next, with shielding the semiconductor device from light, a voltage of a predetermined level is applied to the device from a power source . Weak luminescence emitted from the semiconductor device is magnified through the microscope , and is then input to the photomultiplier . The intensity of the luminescence is multiplied to a visible level so that the luminescence image is picked up by the camera to be displayed on the display , while the amount or intensity of the luminescence is accumulated as the form of the number of photons and stored in the internal memory of the controller for a predetermined period of time. By superimposing the image obtained as a result of accumulating the luminescence over the previously stored image of the device in the controller , it is possible to detect and measure the positions and distribution of the luminescence. Then, it is evaluated that a device with a greater amount of luminescence has a greater number of hot carriers generated, and therefore has a shorter lifetime because the device characteristics are degraded by hot carriers.
