Abstract
According to one embodiment, a semiconductor device includes a semiconductor substrate, a semiconductor region, a first and second electrodes. The semiconductor region is provided on the semiconductor substrate via an insulating film. The semiconductor region includes a protection diode. An overvoltage causes breakdown of the protection diode. A PN junction of the protection diode is exposed at an end face of the semiconductor region. A first and second electrodes are provided distally to the exposed end face of the PN junction. The first and second electrodes are connected to the semiconductor region to provide a current to the protection diode.
