Abstract
A metal oxide semiconductor device is featured by the provision of at least two field plate elements interposed by an insulating layer. The field plate elements are connected from a drain electrode and a source electrode. Otherwise, they are isolated from the respective drain electrode, source electrode, and gate electrode. Each of the field plate elements consists of Al, polycrystalline silicon, or the like. An extensive conductive layer is provided which overlaps vertically each of the field plate elements.
