Abstract
A semiconductor device which comprises an SOI substrate having an insulating layer between a semiconductor substrate layer and a semiconductor layer in a surface of which a semiconductor element is formed, and at least one external terminal provided, via an insulating film, on a surface of the semiconductor substrate layer and electrically connected to the semiconductor element. The semiconductor device further comprises a contact portion constituted by a conductive film reaching through the insulating film to electrically connect to the semiconductor substrate layer; and a potential fixing electrode provided, via the insulating film, on the surface of the semiconductor substrate layer and connected to the contact portion.
