Abstract
A semiconductor device that includes a through hole forming region, an insulating wall, a semiconductor substrate, a side wall insulating film, and an electric conductor. The insulating wall has an inner peripheral surface surrounding the through hole forming region. The semiconductor substrate has the insulating wall buried in one of surfaces thereof. The semiconductor substrate has a through hole whose side wall is provided outwardly from the inner peripheral surface of the insulating wall. The side wall insulating film covers the side wall of the through hole and the inner peripheral surface of the insulating wall. The electric conductor is provided in the through hole of the semiconductor substrate via the side wall insulating film.
