Abstract
The electrostatic protective device includes an insulator and a semiconductor layer. The semiconductor layer includes a device forming region and a device separating region. The device forming region includes a primary first conductive impurity diffused layer, a body region, a secondary first conductive impurity diffused layer, and a second conductive region that are arranged in order. The second conductive region includes a second conductive impurity diffused layer separated electrically from the body region. The device separating region includes a device separating layer that surrounds the device forming region. A gate electrode is further provided on the body region in the semiconductor layer with an insulating film interposed in between.
